Garmin Forerunner 245 | In-depth review and opinion


Esta página está disponible en español

Si te gusta correr (lo que hoy en día viene a llamarse «runner») tienes muchos motivos por los que estar interesado en el nuevo Garmin Forerunner 245The FR245 is right at the top of the range: it's not as expensive as the top-of-the-range models, but it has almost the same features as them.

I have been using the new Garmin Forerunner 245 Music for over a month. It is not a loaner unit but I bought it so that I could play it for as long as I needed, and of course also so that I could keep it close by and answer any questions that come up that are not covered in this (difficult) test.

If you like this analysis and find it useful to decide the purchase of your next GPS watch, please use the links you will find on this page (well, you can buy that GPS watch you want or anything else). You will not pay more than it is worth, but the seller will pay me a small percentage which is what helps to cover the costs of hosting the site, buying watches and, obviously, my work.

Once I've explained everything and after more than a month of getting to know each other, I'm ready to tell you all the good and bad things about Garmin's new model. Are you ready? Here we go.

The Garmin FR245 Music is a great choice if you're looking for a reliable, all-round watch to go with you on your workouts. It's taken almost all of Forerunner 645's features and put them into a more affordable option. And it's even got more range and a more up-to-date pulse sensor. For this price, no other model offers a longer specification list than the Garmin Forerunner 245.

User Rating: Be the first one !

The good

  • It has almost all the functions of its higher-ranking siblings
  • Optical pulse sensor is slightly better than the previous version
  • Career dynamics, training status, training effect...
  • It has a lot of features that have never been seen before in a Garmin of this price

The bad

  • Without Garmin Pay
  • No magnetic compass
  • Not that I would expect this, but for some people the absence of a barometric altimeter can be a problem, especially since it does not track ascended floors or does not allow you to be compatible with the Connect IQ Garmin Running Power
  • Garmin still has work to do on the new satellite chipset

Garmin Forerunner 245, at a glance

The Garmin Forerunner 245 doesn't have any new features we've ever seen, but it does have many features that we used to were only present in higher-end devices.


If we compare it to the Garmin Forerunner 235 (which is the model Forerunner 245 is coming to replace) you'll find many options that weren't available before. They're not just related to software features, there are also hardware changes in the new model.

  • New Garmin Elevate 3 optical sensor with Pulse Ox (pulse oximetry estimation)
  • New chipset Sony GPS for greater autonomy, compatible not only with GPS but also GLONASS and Galileo
  • Adds music playback (Forerunner 245 Music only) and support for streaming platforms such as Spotify or Deezer
  • Performance MetricsThe same as the ones we can find in the high range from Garmin Fenix 5 This includes Training Status, Recovery Status, Training Load, etc.
  • Career Dynamics MetricsAgain, this is the first time we have seen it in the 2xx range. However, you will need an HRM-Run or HRM-Tri pulse sensor, or the Running Dynamics Pod in order to obtain data on stride length, ground contact time or vertical oscillation ratio among others
  • Navigation complete route planner (without maps), with digital compass
  • New security and tracking features with incident detectionYou can send an alert to the chosen contacts in case you detect a sudden deceleration or any other situation that could lead to a fall. You can also send a help message simply by pressing a button
  • Profiles of swimming pool and gym with repeatability
  • Allows to pair sensors ANT+ and, besides, BluetoothThis is the same as the other current models, but the 235 did not offer it. However, it is not compatible with cycling potentiometers
  • Connection WiFi for workout, activity and music synchronization (Garmin FR245 Music only)
  • Compatible with training plans of Garmin Coach or with advanced trainings created directly on the platform
  • 42.3mm sphere diameter and only 38.5 grams in weight
  • Lens with protection Gorilla Glass 3
  • Autonomy of up to 24 hours with use of GPS, or up to 6 hours if we are playing music
  • Add Virtual Partner and Virtual Racer
  • New widgets with Body Battery and stress monitoring

If you thought Forerunner 245 was simply an FR235 with the added ability to play music, you were very much mistaken. In many ways the FR245 is identical to the top model, the Forerunner 645 that was introduced last year.

What do you mean, you want to know how the two models compare? Well, ask and you shall receive!

Garmin Forerunner 245 vs Garmin Forerunner 645

If you take a look at the list of features on the Garmin Forerunner 245 and Garmin Forerunner 645, you'll see that they're both pretty much the same. So it's only natural that you'll start thinking about why there's a theoretical price difference between the two, if they both offer the same...

There are a few differences you should be aware of, but here are the features that Forerunner 245 doesn't have:

  • The Garmin Forerunner 245 does not support Garmin PayPerhaps this is what has caught my attention the most, as Garmin is trying to incorporate wireless payment on all of its devices, as it is an additional source of income for Garmin
  • There is no barometric altimeter Therefore the height measurement will be done exclusively through GPS (which is not exactly the most reliable thing in the world) It's enough to run on asphalt but if you intend to tackle slopes you might miss it
  • Due to the absence of a barometric altimeter, in the FR245 there is no monitoring of ascended floors
  • And for the same reason it is also not compatible with Garmin Running Power
  • It has no Strava function. I mean, there's no Live Strava segments nor Strava Beacon
  • While the FR245 is made entirely of plastic, the 645 has a stainless steel bezel
  • There are no profiles of skiing, snowboard or rowing sportsThey are present in 645

You must not forget that since it is a model that has just arrived on the market it also has some of the new features present in the whole range and which are not in the 645.

Thanks to Sony's new GNSS chipset the autonomía of the FR245 is far superior, especially if we talk about its operation with GPS only use, with 10 hours more battery life in favor of the 245. Pulse Ox.

Garmin Forerunner 245 - Optical Pulse Sensor

Thanks to the new wrist heart rate monitor there are two new things that FR245 will track: Body Battery and SpO2.

Garmin Forerunner 245 - Widget Body Battery

So if you have doubts between the two models you'll have to think about which options you prefer. But let's get to the point and see how it works.

Use and enjoy training

There aren't many changes in this new Garmin Forerunner 245 but, at the same time, many things are new or different. The user interface has changed, adding icons next to the different menu options. Thanks to the new processor it's now a little faster. But the important thing is that if you come from any other Garmin model you'll still feel at home.

With each new model, Garmin adds a unique face to the model, this time showing the total distance you've run in the current week. It only shows kilometers recorded in the running profile, if you've cycled 300km or walked 95km it won't appear on that screen.

Garmin Forerunner 245

Don't worry, you can select any of the classic options directly from the clock menu or you can download any other from the new Garmin Connect IQ App Store. Or use the Face It option to customise your own face with the photo of your choice.

Garmin Face It

Widgets have also seen improvements. When you use it, you'll see changes in the effect when you slide screens, but I'm talking about new information.

To give you an example, we now have the new Pulse Ox widget that shows you the last oxygen saturation reading (taken at night, if you have the option enabled), or that you can take at that very moment.

Garmin Forerunner 245 - sp02 measurement

As I was saying, this is not the only new widget that Garmin has included in FR245. We also have the History and Last Activity widgets.

Garmin Forerunner 245 - History

Garmin Forerunner 245 - Last activity

The notifications and the calendar also show a different image. And speaking of notifications, it now shows the colored emoticons. But we still can't answer messages from the clock (it only allows to send some previously established texts, and only in Android phones), it doesn't show the photos that are sent to us, and when it comes to see the messages, it only shows the first lines. So you can forget about reading those 500-word work emails directly on the clock.

Forerunner 245 is fully compatible with the advanced workouts you can design in Garmin Connect, both in the application and on the website.

Garmin Forerunner 245 - Advanced Training

Speaking of training, another novelty is the Garmin Coach adaptive training plansIt's a free training platform that allows you to choose a target distance, to be performed in a given time. Once you select your target, Garmin Coach will ask you which days you want to train and you can even choose one to be the day of the long roll.

Once the workout is created, it's not a fixed thing that you have to stick to, Garmin Coach will modify the workout plan to suit you. If one day you haven't trained as you should, it will be taken into account in the following days' workouts, adapting them to those changes. 

I leave you this gallery so that you can see for yourself what it offers and what you can select.

You know the best part? IT'S TOTALLY FREE!

I haven't tried them personally because my main sport is triathlon and my training is guided by my coach, so I can't tell you more about how it works. Anyway, I guess you understand the concept of how it works.

Let's talk about sensorsThe Garmin FR245 is compatible with both ANT+ like BluetoothSo if you come from a different brand (mainly Polar, Suunto or TomTom) and already have a pulse sensor, you can be pretty sure you'll be able to use it with your new watch.

I'm not forgetting that FR245 has an optical pulse sensor, but as you'll see later on there are occasions when you'll prefer to keep using the classic chest sensor.

Heart rate sensors aren't the only ones you can pair with the watch, it supports all of these:

  • Heart rate (ANT+/Bluetooth)
  • Footpods (ANT+/Bluetooth)
  • Speed and/or cadence for bike (ANT+/Bluetooth)
  • Smart lights (ANT+)
  • Garmin Running Dynamics Pod
  • Garmin Varia Radar
  • Garmin Varia Vision
  • Garmin VIRB cameras
  • Garmin Tempe Temperature Sensor

But speaking of heart rates, the Garmin Forerunner 245 includes the latest revision of the Garmin wrist heart rate monitor that includes the Pulse Ox feature, which we first saw on the very expensive Garmin Fenix 5X Plus. The new sensor is called the Garmin Elevate 3.

In addition to the pulse oximetry estimation there are also small changes in the pulse measurement (I will expand on this later). But before we go any further... What is pulse oximetry and what can you do with the data it provides?

Pulse Ox takes an estimated reading of your blood oxygen saturation. It does this at night, provided you have the function enabled, so you can get advanced sleep metrics.

Garmin Forerunner 245 - Advanced Sleep Metrics

Although in principle on FR245 Pulse Ox only works at night, you can take a SpO2 reading at any time of the day through the Pulse Ox widget.

Garmin Forerunner 245 - Measuring Pulse Oximetry

What it lacks is the ability to monitor it throughout the day, something that is present in the top-of-the-range models.

But in those the approach to this metric is different, being oriented to climbing and hiking in high mountains. Anyway, if you don't usually go around high peaks or move in altitude, you don't lose much.

Press Ox is that red light that lights up from time to time on the back of the clock (not to be confused with Amsterdam's red light district).Garmin Forerunner 245 - Measuring sp02

Returning to the sport part, Forerunner 245 has more features than the model it replaces, but not as many as we can find in Forerunner 645.

Garmin orients the FR245 (and therefore the entire FR2xx range) as a watch exclusively for runners, so it does not have as many functions as the FR645, but we do have more possibilities than before.

We have sports profiles of career (outside, inside track and belt), cycling (exterior and interior as well) and also andar, swimming pool and other indoor sports such as elliptical or weight training.

So... what do we lose with respect to 645? Well, other sports like rowing or skiing. And obviously we don't have the multi-sport profiles we can find on FR945 either.

Each sport I mentioned above allows individual configuration; almost all options are customizable; from data pages to alerts, automatic lapping, GPS configuration and so on.

What it means is that you can have a running profile not only with the data pages you need specifically for this sport (pace, etc.), but also other settings such as alerts or automatic laps for sports like cycling, where you will also prefer to see speed instead of pace.

Besides the data pages, this is all you can set up:

  • Alerts (heart rate, run/walk, pace, time, distance, cadence, calories)
  • Metronome
  • Automatic return, also allowing you to select what data you want to see when it is displayed 
  • Automatic Pause
  • Automatic Scroll
  • GPS Modes (GPS, GPS+GLONASS, GPS+Galileo, Ultratrac)

To define your data pages you can select from one to four data pages per screen, as well as add some of the default pages; such as the activity map, music control and race dynamics. And by the way, the font that Garmin uses now is different, a little more rounded than the previous one.

Garmin Forerunner 245 - New Font Type

I have talked about running dynamics, yes, because this is another option inherited from the superior models and now found in the FR245. You must remember that in order to display these metrics you will need an external accessory: Garmin HRM-Run, HRM-Tri or the Running Dynamics pod.

Garmin - career dynamics

When you're done training, you can sync your activity with the Garmin Connect online platform, using Bluetooth if you're in close proximity to your phone, or WiFi if you've set it up on your Garmin Forerunner 245 Music (regular Forerunner 245 doesn't have WiFi). If neither option is viable, you can always use the USB data cable.

After syncing, you can review your workout on the Garmin platform, both in your phone application and on the website. And as a bonus, Garmin Connect also includes the list of songs you've been listening to while you've been running. It's completely private and only you will see it, even if you share your workout with a friend.

Garmin Forerunner 245 - Synchronized Training

Route navigation

Route navigation is another feature that was not present in the mid-range in the past, but has made an appearance in the Garmin Forerunner 245.

It's exactly the same as the one we have in the FR645, so it's a slightly cut-down navigation compared to what you can have in a Fenix series watch. And I'm not talking (exclusively) about the maps in the Fenix 5 Plus, but about another set of slightly more advanced navigation features.

Make no mistake, this is not a criticism. It's simply that the navigation we have in Forerunner 245 is slightly simpler than the other models. Is that bad? Not necessarily. It's perfect for the occasional route use you may need, but it doesn't have the feature level of the more advanced models.

On the Garmin Forerunner 245 we have three specific functions for route navigation:

  • TravelsTo follow predefined routes that you have created from the app, from the web or imported from external services
  • ActivitiesThe following is a list of activities that you have completed in the past
  • Saved LocationsNavigate to a saved location, which you have marked from the clock (only directly, not with a guided path)

Garmin Forerunner 245 - Navigation menu

La realidad es que la función que vas a usar es la de «Trayectos». Con esta función puedes crear una ruta fácilmente en Garmin Connect.

Garmin Forerunner 245 - Creating Routes

You can create it manually or import an external file, whichever you like, but if you want to create a route, it's much more convenient to do it from your computer. The Garmin Connect application also allows you to create routes, but it's a pain.

Garmin Forerunner 245 - Creating Routes from the Connect App

It allows you to set your starting point and then you can keep putting more points on the map, but it's anything but intuitive. You can design the route... but it's going to take you a while to get there.

Pero por otro lado tienes la opción de crear una ruta con la opción «Automática», tal y como ves en la captura superior. Es bastante más interesante porque simplemente seleccionas un punto de inicio, la distancia aproximada que quieres recorrer y en qué dirección quieres dirigirte. A partir de ahí la app te calculará una opción de forma automática.

Garmin Forerunner 245 - Creating Routes from the Connect App

This is the perfect option for those of you who travel and don't want to rack your brains trying to figure out which routes to take when you get to your destination. You'll get a navigation route that's based on Garmin's popular route feature, called Trendline. With data from thousands of activities uploaded to its servers, Garmin knows which routes and trails are used by other users in that same area.

After creating your route (from the web, application, imported or whatever) you can synchronize it directly to your clock and, when you are about to start your adventure you can enter the options to load the route you have synchronized.

From then on, the clock display will show a route like the one below.

Garmin Forerunner 245 - Navigation

If you enter the navigation options you will also be able to zoom or scroll the map to see different details

Garmin Forerunner 245 - Zoom map

So what are the functions you're missing from the Fenix range or Forerunner 945? Obviously in the case of Forerunner 245 there are no maps, but it also doesn't have functions like points of interest, Sight 'n Go and the like. But perhaps most importantly, in FR245 we don't have a magnetic compass.

This means that the clock will know where you are looking only if you are moving, but if you stop at a fork to try to decide which way to go, the map will not move with your movements.

That's the main drawback we found in FR245's navigation, apart from this detail it's something totally functional for your escapades in the forest.

Training and Performance Metrics

One of the most interesting aspects of the new Garmin FR245 is the advanced performance metrics. This was the main feature shown on the Garmin Fenix 5 and Garmin FR935, and now they have finally reached the mid-range.

This is a collection of algorithms that, far from being developed by Garmin, is the work of the Finnish company Firstbeat. With many years studying and developing heart rate functions, they are the ones behind most of Garmin's features. Just take a look at your website to see the number of proprietary algorithms available in Forerunner 245.

Garmin Forerunner 245 - Firstbeat Features

All this data is available on the clock through a widget. Let's say it's the cover for all the performance metrics that Garmin (and Firstbeat) call Training Status.

The data shown on the display will change each time you complete a workout, updated with the latest activity and putting it in context with what you have been doing up to that point. It will also change if you don't train, reflecting for example that you are recovering.

This information is extracted from the VO2max estimation, something that was already present in previous models.

Garmin Forerunner 245 - VO2Max

This estimate will be reliable after several weeks of data recording, so before you have consistent information you should have done some workouts with different intensities. It is a metric that needs to be adapted to you and how you train, you should wait at least that long for weeks of varied and serious workouts before you begin to see meaningful data. 

Within that same widget we also have access to the recovery status, including the remaining hours until you are fully recovered.

The main news is that now, in that sum of hours, you will see the recommendation you should take into account about your next training, if you can train normally or it is better to take it easy.

Garmin Forerunner 245 - Recovery status

Below is the training load screen, where you will find the indication of COPD accumulated in the last 7 days.

>> What is COPD? Excess oxygen consumption after exercise (Excess Post Exercise Oxygen Consumption).

Training Load is just a concept, a figure that represents the physiological demands you've been experiencing with your training, taking into account that each of us has a different level of endurance.

That means that this number is entirely personal, and will also vary with the time of the season you are in. A training load of 600 may be optimal for me, but it is surely a week's rest for a professional.

And in the same way that training load can be very high when I'm out of season, or relatively low if I'm training for a specific competition.

This metric uses historical data to determine if your training load is correct or if you are increasing your load too quickly.

Garmin Forerunner 245 - Training load

As I said at the beginning, all this data is summarized in the initial screen of the widget. 

Garmin Forerunner 245 - Training Status

It is divided into two values: exercise and load. The arrows indicate how the training is affecting you. Here what we especially do not want to see is that our fitness (exercise) decreases while we increase the load. That means that we are working too hard but without much benefit, so you should increase the intensity of the training. 

The news doesn't end here. After completing a training session we have a new screen, called Training EffectHere he separates aerobic and anaerobic work.

Garmin Forerunner 245 - Training Effect

These two metrics indicate how the workout you have just completed will affect your fitness. Being separate, it allows you to better categorize the aerobic and anaerobic impact of your workout, since depending on what you are training for, you will prefer to improve one or the other aspect. Because the physical changes you are looking for by training for a 5km run are completely different to those you are looking for in a marathon.

Garmin Forerunner 245 - Training Effect

This data is not only displayed on the clock or when you enter history, it is also available in data synchronized to Garmin Connect.

Garmin Forerunner 245 - Training Effect

Are the values shown valid? I think in general they are quite real. The workout shown was mainly a steady pace start, but including three or four short intervals. This has resulted in an aerobic effect of 3.5; considering that it was not an excessively long workout I think this is correct.

I also got an anaerobic effect of 1.3, thanks to the short intervals I did. It wasn't a training series as such, just a few changes of pace and not too difficult, so I wouldn't expect a higher number.

Now, how about a near-threshold pace roll? I started out easy, increasing the pace slightly in the last few minutes of the workout, but with the sole intention of increasing the mileage. No intervals or a pace that would be too much for me.

Garmin Training FR245

Presumably for this workout we should find good aerobic value, without affecting anaerobic capacity too much, right? At least that's what I intended with this workout (because I'm going through a solo injury). So what does the Garmin Forerunner 245 say about it?

Garmin Forerunner 245 - Training Effect

Yes, it seems that we are in tune. You can see that it was not a recovery training as the heart rate was over 160, but as I did not make any change of pace I entered Z5, there is no anaerobic improvement.

In this sense, the information provided is good because it is perceptible and the average user can use and understand it. The key is to know how to mix your workouts so you don't get stuck doing the same thing all the time.

The first version of Training Effect was a simple value that gave a qualification to our training, but without differentiating in any way. We could get the same value for a long run of 3 hours as for 30 minutes of intervals. And, obviously, they are two exercises that produce very different effects on our body.

Music playback

When you buy the Garmin FR245 you have two options: With or without musicIf it's the non-music version that interests you, then you can move on to the next section. Are you a music lover? Then don't go anywhere, stay here with me.

Well, I lied to you anyway. Music isn't the only thing that's different, the selection of colors available also varies between the Garmin Forerunner 245 and Forerunner 245 Music. It's not just the color of the strap, but also certain accents on the watch. 

In the case of choosing the version without music, you can opt for grey or maroon. Which as I say is not only the strap, also the accents are different. There is a ring on the main button and a small line next to it.

You don't like those colors? Then you can choose from three other colors, but only available in the 245 Music version: black with red details, white (with black bezel) and light blue.

Garmin Forerunner 245 - Specific accents

But hey, enough talk about colors, we're here to talk about music. Only the Garmin Forerunner 245 Music has the hardware to make it all work, including memory to store files and the ability to use Bluetooth to stream music (to a headset, speakers, your car, or whatever you want), as well as WiFi, which allows you to sync music wirelessly - and your workouts and other data as well.

Garmin Forerunner 245 - WiFi

In terms of available memory, the watch has a total of 4GBWe have a total of 3.6GB of available space that is shared among all of the stored files, with the rest reserved for use by the system. This includes not only music, but also the rest of the training files, applications, etc. But all of this takes up very little space, leaving almost all of the space available for music. According to Garmin's calculations, about 500 songs in total.

From here we have several options on how to transfer music. The classic option, in which we simply transfer files manually to the clock; or do it 2019 style, synchronizing the music from our favorite music streaming platform. I'll start with the manual method.

Manual music sync to the Garmin Forerunner 245

We can do this through the Garmin Express application or, if you use Windows, by dragging files directly into memory. By connecting the clock to the computer and activating the computer's MTP mode, we have access to the two available memories.

(I will use the examples of 645, but in 245 it is all exactly the same).

Garmin Forerunner 645 Music - Internal Memory

On a Mac, you only have access to main memory, not media memory. But there's a catch, if you install the Android file transfer application (Android File Transfer) you will be able to see that memory and operate normally with it.

Android File Transfer and FR645

However, it is more advisable to do so through the Garmin application, since the corresponding playlists will be created for each album you synchronize, and you can later access the music through the names of artists, albums, songs, etc.

Simply select what you want to sync and send it to your device.

Garmin FR645M - Music Transfer

Synchronization with music platforms

Manual music synchronization is fine, but I bet 5 real fleece that many of you don't save any music file on your computer anymore and depend totally on streaming platforms. You don't have to worry, because FR245 also allows you to synchronize your playlists to the clock.

Right now Garmin has applications for Deezer, iHeartRadio and yes, Spotify too!

Garmin Forerunner 245 - Spotify

How does it work? First, you need to install from Connect IQ the application of the music provider of your choice -Spotify, Deezer or iHeartRadio-Once downloaded, you can find the app among the music provider options on the clock.

All the information I will show will be in reference to SpotifyAnd based on the number of downloads from the different platforms, it's the one most of you choose.

Adding music and podcasts

I'm going to assume that since you're a regular Spotify user, so you already have different playlists created on the platform, this works for both lists created by you and lists created by others (whether other users or Spotify), as well as dynamic or latest playlists. And you'll also be able to sync podcasts that you've subscribed to.

You only have to mark what you want to listen to and, once done, it will use the WiFi connection to download the files, which you must have configured in advance. You can do it from the clock, but I recommend that you do it from the application on your computer or phone as it is much easier to write the password there than to do it on the clock.

However, it has to be a private network with a password, it is not possible to do this in open networks such as hotels, airports or similar access points.

I found the download to be reasonably fast. Not as fast as if you were downloading from your computer, but it's not an eternal process. I downloaded a playlist of 200 songs in about 15-20 minutes. But the best part is that it doesn't require the user's attention at all.

Remember that this is the first download, so if you want to update the list tomorrow because you've added 10 new songs, you'll only have to download those 10 songs, not the whole list again. And unlike other platforms like Deezer, it seems that in Spotify the limit is set by the amount of free space in the clock memory (Deezer limits to 500 songs stored in memory).

Playing Music on the Garmin Forerunner 245 Music

Once we have everything synchronized to the clock it's time for the party. You can play music while you're training, but also at any other time. Simply access the music option through the widget or by pressing and holding the lower left button on the clock.

You'll be asked what you want to play. You can add headphones in the same way you add any other sensor, and you can have more than one audio output source paired (but you can only play music to one device at a time).

The playback screen has direct access to three functions through the buttons: pause, next song and play menu. The outer circle indicates how much of the song has been played and how much is left over.

Garmin Forerunner 245 - Playback screen

From the menu you can access the rest of the options, such as modify the volume, change the song, activate the shuffle mode or return to the music library.

You may wonder what the sound quality is like. It's not bad, but it doesn't offer any advanced codecs like apt-X or AAC. Data transmission is up to 328kbps, which is pretty decent but not perfect.

Remember that data transmission is digital, so the headphones must have a good DAC (digital audio converter) to enjoy good audio quality.

But considering that you will use this option mainly while training with a headset and that you will be more focused on keeping the rhythm in the intervals... it is perfectly valid.

The only problem you might have would be the signal cuts. But that depends on many things, and the watch wouldn't be the only one to blame. If you have cuts it could be perfectly well the watch; but also the headphones, the distance between the two, other things you have on you that are causing interference, or simply where you're wearing the watch.

I haven't had any disconnection problems with the different types of headphones I've tried, from Jaybird to AirPod copies. Maybe I can remember some cut-off occasion if I was walking with my hands behind my back, but not while running at any pace.

Garmin FR245 Wrist Heart Rate Monitor

Garmin Forerunner 245 - Optical Heart Rate Monitor

As I said earlier, the Garmin Forerunner 245 comes with the latest Garmin Elevate optical heart rate sensor. This is version 3, in theory the latest and most advanced Garmin.

The main difference from previous units is the Pulse Ox sensor and the red LED required for this particular function, but it also has some improvements that should make it better than version 2.

Based on this my expectation was to find something with a slightly higher registration than previous versions, but I also didn't expect to find an abysmal change. The optical sensors have been around for quite some time, if they had a wide margin of improvement it would have been done already, but it is possible to improve them by 1-2%, which is what I expected to find.

I'll make a little spoiler before I go into all the comparisons: Don't keep your chest sensor in the drawer yet, you're going to keep using it.

And as a reminder, keep in mind that an optical pulse meter will not work the same for everyone. Tattoos, body hair, skin tone... all of these can make a big difference between people.

These tests are conducted with a wide spectrum of users: one, which is me. What works for me may not work for someone else in the same way, or may work better for them.

But the most important thing is that you have to wear the sensor correctly, tight (but not as if you were making a tourniquet on your wrist) and leaving a separation of approximately one finger in relation to the wrist bone. If you make sure to follow these details you can be sure that you will get the best possible results for your skin color conditions, etc.

I'll start the comparison with an easy-paced workout. It couldn't be simpler.

For this training I was carrying an FR245 with me, both using the wrist heart rate monitor (both use the same sensor). The Polar H10 sensor was carried to validate data, and was paired with the Polar Vantage M.

Garmin Forerunner 245 - Optical Heart Rate Comparison

What can we see in this graph? All three are practically the same. There is only a small difference in the FR245's, around the 26 minute mark, which I am sure occurred when I adjusted the watch strap. It is at this same point that I slightly change the intensity of the workout, when I reach a steep climb.

Let me zoom in on that area. Leaving the point error aside, I want to focus on the ups and downs of the graph. We can see that even though the optical pulsometer reaches the correct pulse values, there is a slight delay compared to the chest sensor.

Garmin Forerunner 245 - Optical Heart Rate Comparison

It's something that happens exactly the same when I start to increase the intensity as when I'm recovering.

I start with a smooth and easy pace and finish with three different intervals, similar to a fartlek. This time I compare Forerunner 245's optical sensor with that of the Polar Vantage M. And with those two, I'm wearing a Garmin FR935 with the Garmin HRM-Tri sensor to try and figure out which one of them gives the best result.

At the beginning of the training you can see three perfectly aligned lines, but there is also some hesitation at the end with the intervals.

Garmin Forerunner 245 - Optical Heart Rate Comparison

As there is not much to assess in the first part, I will focus on that end of the training with the changes of intensity.

Garmin Forerunner 245 - Optical Heart Rate Comparison

As you can see, the same situation is repeated as before. There is a slight delay in the time of the climb and descent, but in this case the FR245 is somewhat faster than the Vantage M. Both Garmin and Polar offer the same heart rate data, but the Polar needs three or four more seconds to reach it.

There is also a peak around the 33-minute mark, both on the FR245 and the Vantage M graphs. Why is this? I had to cross a street, and it seems that neither of them were happy about the sudden stop. We must not forget that all this is based on an algorithm, so if there are dramatic changes it will be reflected in how it displays the information.

The plan was to do 6×400 with a 30-second break between sets, but clearly I can't even count, and in the end there were 5... well, it's the thought that counts.

They are not as intense as I would like, but being in full recovery is what I dare to do at the moment.

This time I change things a bit again. Obviously I still use the optical pulse sensor of the FR245, but I add the new Suunto 5 to the comparison, and the Garmin FR945 is paired with the Polar H10.

Garmin Forerunner 245 - Optical Heart Rate Comparison

At first glance we can see that already during the warm up there is some problem with the FR245. Maybe I didn't wear it tight enough, because I remember to adjust the strap but already quite late in the training.

So that's no excuse, because even if you lose the first interval, from the second one you already recover. It's rare because usually in easy conditions like this heating the optical sensors usually make it almost perfect, in this case it's clear that it took some work to start recording correctly.

I will now expand the interval section.

Garmin Forerunner 245 - Optical Heart Rate Comparison

Clearly, the first one is bad. Suunto 5 does it much better, although in recovery it also gets lost.

The second and third are not bad at all. The third has a somewhat strange peak, but within the usual range of optical sensors, but after making the recovery correctly in the fourth interval it makes a frankly bad start again.

This time it was the Suunto 5 that performed best, although when the Garmin Forerunner 245 had a good interval the truth is that the graph is quite positive.

Time to change gears, let's pedal. I know I said this is a running clock, but who doesn't like to take their bike out for a spin once in a while? 

In the case of cycling the optical sensor logging data has always been typically bad, so I didn't expect the FR245 to improve it too much. But I ended up a little surprised.

I'm not saying he's as good as running, but he's improved quite a bit. It won't make you forget about the sensor in your chest, but an improvement is an improvement and I have to stress that.

This is a simple cycling workout, just starting with the warm up (well, more than warm up is going to the zone I use to do my intervals), so the first few minutes are spent between traffic lights and roundabouts. Remember what I just told you about the algorithms? Well, you don't like this too much either.

For this test I used the HRM-Tri sensor paired with a Garmin Edge 1030, comparing it to the optical sensors in Forerunner 245 and Forerunner 945. The light blue line corresponds to Forerunner 245, while the red line is that of the HRM-Tri sensor.

As I said, there are three different parts to training: travel, intervals and cool down.

Garmin Forerunner 245 - Optical Heart Rate Comparison

The scrolling part is pretty bad, so I'll just focus on the part of the intervals that is really interesting, because that's the focus of the exercise. It was just 10×70″ with a rest period of 50″. It's this part that I extend.

Garmin Forerunner 245 - Optical Heart Rate Comparison

Déjame decirte que me sorprendió cómo el pequeño FR245 registró los intervalos. Los dos primeros muestran bastante más lag del habitual, pero el resto son prácticamente perfectos. Mucho mejor que en el caso del Forerunner 945 que hace un trabajo bastante pésimo, considerando que es un reloj multideporte y que lo normal es que vea bastante más bici que ese reloj «exclusivo para correr».

Not that I'm saying it's enough to use on the bike, it's not. But it's good to see things are getting better.

As for the cooling down period, it is simply easy to pedal, and we have the same problems as at the beginning of the training.

In general I see an improvement compared to previous models. Maybe it's the hardware or just the usual software adjustments that occur every time a new model comes on the market, but the improvement is there.

It's not enough to make you forget about the chest sensor, you still have to use it for cycling and interval training; but I can tell you that I trust the optical sensor perfectly for easy training and even races where the pace will be constant. The truth is that it works well as long as there are no excessive changes in intensity.

Garmin Forerunner 245 GPS Reception

Just like the optical sensor tests you saw earlier, the GPS comparisons are done in the same way: with the watches accompanying me in my usual training. I wear both the FR245 and other models, and check where the problems appear. I don't have any defined route where I set a score for the simple reason that there are other external factors that we should never forget.

Things like clouds, leaves on trees or simply the satellite position can alter the GPS results from one day to the next, which is why I prefer to do this type of comparison instead of having a predefined path and assess it from there.

In any case, With the new Forerunner 245, GPS comparisons are importantGarmin has changed the GNSS chip to the new one from Sony, which is the one adopted by almost all manufacturers (whether Polar, Suunto...). On the one hand, it allows to significantly improve the clock's autonomy, but the associated problem is that the tracks they have been showing have been worse than those of older chips.

En primer lugar empezaré con este entrenamiento en Sevilla con dos «rivales» interesantes: Por un lado el Forerunner 935 con un rendimiento francamente bueno después de todas las actualizaciones que ha ido recibiendo. Y en segundo lugar el Polar Vantage M, que equipa el mismo chipset de satélite que el nuevo Forerunner 245.

Both Forerunner 935 and Forerunner 245 are configured to log GPS data every second and with the option of GPS + Galileo. Meanwhile the Polar Vantage M does not allow configuration, but natively supports GPS+GLONASS (by October it will also support Galileo).

This is the chosen route: mixed, with a start that should be very easy because it has no sign problems (parallel to the Guadalquivir River), but on the way back very complicated areas through very narrow streets of Seville.

In this second part of the route I don't expect a good record of the track because given the characteristics it's impossible, with very narrow streets of even a little more than 1 meter with hardly any visibility of the sky, but I'm interested to see how it recovers the signal when I get to a more open area.

Garmin Forerunner 245 Music - GPS

This is the first part of the training, going down the park next to the monument of Christopher Columbus in search of the river.

Garmin Forerunner 245 Music - GPS

It is an easy area because of its wide parks and avenues, if any of them is lost here it would be a bad sign. However, the three clocks are almost always on the route, the same is true for the section parallel to the Guadalquivir.

Continuing along the riverbank the result is identical, as well as making the turn and returning along the same route. So far the two Garmin and the Polar coincide fully, so there are not many obstacles to be overcome (at the moment). It is also worth noting that the bridge where the Hotel Ribera de Triana is located is crossed underneath, so the signal is lost momentarily. None of them has presented any problem either on the way there or on the way back.

Garmin Forerunner 245 Music - GPS

Obviously when you enter from the centre things change completely, the coverage is very bad because the streets are extremely narrow. No clock is going to give a good signal in those circumstances, but it is interesting to see how you recover when things go wrong.

In this first section of the entrance on Reyes Católicos street, the three make the right turn, with FR245 being the one that best maintains its composure in the face of difficulties. FR935 loses quite a few metres and wanders over the buildings.

Garmin Forerunner 245 Music - GPS

The Forerunner 245 behaves reasonably well, very similar to the Polar Vantage V. However, the entrance looking for the Sierpes street is bad for the three of them, as they already arrive at that point with many difficulties, being the Rioja street extremely narrow. In fact, given the conditions it doesn't even seem that bad to me.

Garmin Forerunner 245 : First Impressions 1

The descent along Sierpes Street towards the Town Hall is very similar. Slightly wider but also presents the same problems. In this part of the route what I want to analyze is the arrival at San Francisco Square where the clocks can get signal again.

FR245 and FR935 soon join up and plot the same route, while the Polar Vantage M, as seen in its test, is consistent in its mistakes and maintains the original course.

Garmin Forerunner 245 Music - GPS

However, when the Forerunner 245 arrives at the cathedral it makes two strange and too abrupt turns, denoting that it has lost the signal and is simply joining those two points with a straight line.

We are going to change completely and I show you now a training much easier to handle. It is practically a straight line, in one direction and with perfect visibility of the sky. With these conditions I hope that the tracks are simply perfect.

En esta ocasión llevo configurado el FR245 con GPS+GLONASS, y he «actualizado» del FR935 al FR945, utilizando éste la configuración GPS+Galileo. El Polar Vantage M permanece invariable.

Garmin Forerunner 245 - GPS Comparison

By expanding and checking different areas I see some problems, but all related to the Vantage M and FR945, not to the Forerunner 245. For example, this is a problem I usually see in the testing of Polar Vantage. The track is separated about 8-10 meters from the original route, and it shows consistent with that error.

Instead of swerving briefly and returning to the right place, it stays in the fault. It is also a straight line so there is no impact on the instantaneous pace or total distance, but the track usually appears wrong.

I've marked the areas in yellow.

Garmin Forerunner 245 - GPS Comparison

In the meantime, both Garmins behave correctly. Not perfect, because sometimes they deviate 30-50cm from the right place, but quite precise at all times.

A little further down the line it's the Forerunner 945 that makes very strange movements, probably due to its GPS+Galileo configuration. A few days ago Garmin released a beta version to try to improve operation in that configuration mode.

Garmin Forerunner 245 - GPS Comparison

The rest of the route was quite normal and I could not find any flagrant error on the part of FR245.

It's the general trend I've seen in my training with Forerunner 245. Not perfect, because no watch is perfect, but very good for most of the course. Here's another example of a circular training.

Garmin Forerunner 245 - GPS Comparison

In this case, instead of the Vantage M, we have the Suunto 5, configured with GPS+Galileo, and as you can see with the naked eye, the result is virtually perfect on all three watches. 

I always like to take a look at the sharp turns, trying to pinch the algorithms that use the marks, but even if I make two 90º turns in a row it doesn't seem to upset any of them.

Garmin Forerunner 245 - GPS Comparison

There is a slight separation at the end of that image by FR245, but we are talking about centimeters.

The same goes for this other turn, where both the FR945 and FR245 do better than the Suunto 5 which seems to be a bit surprised, but after the last turn Forerunner 245 deviates slightly from the trajectory, maintaining the error, but soon gets back on track.

Garmin Forerunner 245 - GPS Comparison

As I say it is a punctual moment, but it is not the usual one. Here you have another area with numerous turns in which the three clocks mark almost exactly the same track.

Garmin Forerunner 245 - GPS Comparison

So, final opinion? Despite being in its preliminary firmware versions, the Garmin Forerunner 245 has shown a quite solid behavior, and sometimes better than other models using the same Sony GNSS chipset (Polar and Suunto).

But the results are not perfect. Proof of this is that Garmin is working on the GPS firmware and has recently released an update to try and solve some of the first problems I noticed when we selected the Galileo option.

Opinion Garmin Forerunner 245

Garmin has tried to make the best running watch for the mid-range. Has it succeeded? I honestly think so.

The Garmin Forerunner 245 meets all the requirements to become the best-selling Garmin model, simply because it incorporates many of the features previously reserved for the high-end at a cheaper price.

Garmin's upgrade for its best-selling model was successful, both in terms of design (it's reasonably small, but with a very acceptable screen size) and in terms of everything it includes in its software: route navigation, more sport profiles, performance metrics, etc.

It is true that none of them are new, but we must not forget that most of them are functions that a little more than a year ago were in watches such as the Garmin FR935, whose price is practically double.

Not everything is perfect. Garmin still has to work on the firmware of the new Sony chipset, but so do the rest of the competitors. In this sense, all of them have suffered a greater or lesser impact in pursuit of a greater autonomy, at least in the combination of GPS+Galileo. In its GPS+GLONASS configuration I have not had excessive problems.

And as I said at the beginning, there are a couple of things I miss: wireless payments via NFC and barometric altimeter, both of which are available on the Garmin Vivoactive 3, a cheaper and simpler watch than the Forerunner 245.

Leaving aside the slightly improved appearance of the GPS and the absence of these two functions, the FR245 Music is a very serious watch that I have been able to train with perfectly. All these improvements that Garmin has added to the FR235 are the icing on the cake, making it without a doubt the best model in the mid-range of running.

  1. I don't understand how being Garmin the strongest company in the world they don't consider very interesting to add the eSIM option to their watches, I don't understand it, it's ok that it consumes battery, but you can always deactivate it when you don't need it, but if you want to do sport without the mobile I think it's an essential option, to be able to call in case of emergency, or to be able to send your location in a message. What do you think?
    Thank you very much for your work.

    1. They already have a clock with eSIM, the Vivoactive 3 LTEBasically they have launched it to do a study of the real interest, and from there I suppose they will make decisions... but of course they have more than thought about it.

  2. Garmin is going to drive us crazy (I'm kidding): this 245, the 645, the F5 (not Plus) and Instinct can be found in the vicinity (and for not much more sometimes) of the 300
    Now seriously, something that comes to mind: Are performance metrics (training status, recovery, load, etc...) really necessary for trail? I know that, well, if I want everything, at Fenix but still...
    Let's see how the analysis goes!

    1. These are useful metrics if you train daily and do variety in your workouts (intensity, tempo, etc). If it is more for sporadic use and less structured it will be just another piece of information that may not be useful to you.

  3. I bought the 735XT a long time ago, I always thought it was a great model, but I don't know why it has never been talked about much... Right now you can find it for less than 280 Euros and I think it has almost everything this new Garmin model offers (the model without music).

  4. Hi, Eduardo.
    I have the Phoenix 3 and I only run on roads and mountains in 1 hour runs.
    How do you see it for unpretentious trail running?
    can link to Wikiloc paths?
    thanks and congratulations on the job.

    1. If you don't mind running out of the barometric altimeter you'll have no problem. The navigation is the same as on the Fenix 3, and you can pass routes without any problems.

  5. Well, with this model I can see in situ the unevenness that I have made? or I have to wait to lower the training to the app?

    1. No, Forerunner 245 does not have a data field with an accumulated slope, mainly because it lacks a barometric altimeter and the data shown here would not be useful.

  6. Actualmente tengo el Garmin 630 (que al poco se dejo de hablar de él cuando salío el 645 rápidamente) va como un tiro, pero por capricho me gustaría cambiar de pulsometro, pero veo que el mío era de «gama alta o medio alta» ¿me recomendarías el 245? o coger el 935…

    1. The 245 has many more features than the 630 so there's nothing to lose. With respect to the 935 I say the same thing; unless you do triathlon or need an altimeter, in the 245 you will find almost the same and at a lower price.

  7. I understand, maybe I'd get the Phoenix 5 S plus I guess? I'm in a sea of doubt.
    I wouldn't worry too much about the altimeter either.

    1. You have a lot more options obviously, but you already have to value if you are going to use them (mountain, maps, Garmin Pay) because of course, you are going to pay for them.

  8. Good Eduardo, first of all I would like to thank you for your reviews, they are very helpful. On the other hand, I would like to ask you about the instantaneous rhythm in this 245 model. If there is something about garmin that I don't like precisely is the instantaneous rhythm from the fenix 3, which is not reliable in any of the current models (except in the vivoactive 3).
    It's something I use every day along with the backbeat, and I need it to be as reliable as it is in Suunto.

    1. Personally, I don't use instantaneous rhythm (I prefer rhythm in turns), but it follows the same tone as the rest of Garmin's models, always showing it in multiples of 5 seconds.

  9. Good afternoon, Eduardo, I wanted to ask you, between the forerunner 245 and 935, which one would you stay with, I am interested in the optical pulse, and advanced metrics, like the calculation of the lactate threshold, thank you very much, and very good analysis.

  10. I have the 235, and my wife wants to take it over. She wants something better than her old Garmin. Seeing as I'm going to have to renovate it, make some asphalt and want to go back to making ultra trail, this 245 is good or almost good. Look at the 935. It'll be cheaper now.

    1. If the target is the trailer then I would value the 935 better, the barometric altimeter is a very important detail

    2. Well, unless you're serious about the ultratrail and you're going to be spending a lot of hours in the mountains and on slopes, I'd really prefer the Forerunner 245.

  11. Eduardo, thanks for the article, very well written.
    What are the available languages? Can it be changed to English or Portuguese?
    Is there an option to record an unknown route for me and what do I do for the first time following a friend and then repeat this route by following the instructions on the screen?
    Thank you.

    1. Yes, there are many languages available, Portuguese among them.

      As for navigation, it is indeed possible to re-navigate a previous activity directly from the clock menu.

  12. Good afternoon.
    The fact that it does not have a barometer, when you pass the information to Strava, for example, will not give you the profile of the route taken or indicate the accumulated difference in level?

    Thank you!

  13. Don't you think it's too small? In my case, when I try it on, it looks like a watch for a woman's wrist

  14. Hello:
    Right now the Phoenix 5, the 245 and the 265 are all around the same price.
    Which one would you advise me to buy?
    Soil running 70% asphaltv and 30% mountain

    1. It all depends on whether you value having reliable altimeter data while you're training. If the mountain trips are sporadic I guess not too much, and in that case I'd prefer the 245 with its extended range.

  15. Good morning.
    Unlike my previous partner, I'm between the Garmin 245 and the 645
    Asphalt 20% and mountain 80%
    Or do you advise another kind of Garmin?
    Thank you!

    1. In your case it's the opposite, since almost everything you do is mountain, so barometric altimeter yes or yes. The FR645 is a very good option, being another possibility the Fenix 5S. But the 5S has the disadvantage that the screen is of lower quality because it has less resolution. It would be to go to the 5S Plus that has the screen of the rest of the range, but the price shoots up ...

      If the route tracking you do is basic and what the 645 covers works for you, then I would choose that option (which is also now on sale).

      1. Good afternoon.
        I'm analyzing FR645 and the Fenix 5S.
        I like them both but I don't know which one to choose.
        Which one would you advise?
        645 I see that you have more sports profile (as far as Gym is concerned) and have more resolution. Is Garmin Pay reliable to use?
        But the Fenix 5S has more memory, has the Ultra Track function and when it comes to outdoor functions, I think it's better.

        I'm a mess because I like them both so much... ????

        1. Garmin Pay, if your bank is compatible, there's no problem.

          The main difference in favour of the Fenix 5S is the more complete navigation and that it allows multisport modes such as triathlon. If these two details are not important I prefer the 645 because of the quality of the screen and the lower weight.

  16. Hi Eduardo. Thanks for your analysis. I'm hesitant to buy vivoactive 3 or fr 245. Right now my physical activity is low, but I hope to return to it soon. What do you recommend? Do you think the pulse sensor is much more accurate and worthwhile to monitor daily/sleep activity?
    Thank you for your time.

    1. If your use is sporadic, it is better to opt for the Vivoactive 3. It is worth almost half and you will not notice any difference. The FR245 is a watch focused on running and constant training.

    1. No, it's not available at the moment. I don't know if it's some kind of exclusive with vendors like Wiggle, or that Garmin doesn't allow Amazon to sell it at the moment.

      But right now Wiggle is one of the few places where you can buy it (and it's just as safe as Amazon).

  17. Thanks for your reviews Eduardo, it's hard to be more complete. I read the reviews for the Vivoactive3, FR 645M and FR 245M. I only miss one part that I'm not very clear about. In the review of the VR3 you referred to the lack of information about the target in interval training (the clock does not warn if the pulses are too much for the stretch, or to consult the distance remaining to complete the interval). In the review I see that in the 245M you can set alerts, but I do not know if they are by interval or for the entire race.
    My profile is of a person who runs 10K and I'm starting to do trail runs. I came from an activity bracelet and I wanted something with more autonomy and precision. I had almost decided to buy the VR3 but now I'm opting for the 245M, to make me something expensive the 645M so I'm going to win (GPS barometer).
    Thank you

    1. Yes, in the Vivoactive 3 I specify it because it has that limitation. The Forerunners don't have it and in the FR245 you can program the trainings selecting the objective of it without any problem.

  18. The optical sensor is a piece of junk, same faults as my garmin 735xt, much worse than my polar m430.
    He's a whole minute late to catch any change of pace.

  19. I have never used Garmin and I am considering buying this watch. I would like to know if it gives running cadence data without using pod Running dynamics, either in the watch itself, in the summary or in the training data that comes in Garmin connect.

    1. Thank you, Javier.

      Yes, the clock records the cadence data without the need for an external accessory. It can be set as one of the on-screen data and data and graphs will also appear in the clock summary and in the Garmin Connect analysis.

  20. I've been a user of the M400 polar fleece since it came out almost 5 years ago, I've done some road racing and some cycling.
    I am evaluating the Polar vantage M and the garmin 245.
    When polar meets the upgrade roadmap what important differences will there be between them?

    1. If you're on the Polar platform I think the Vantage M wins big (because you're already used to the ecosystem and that's where you have your current workouts). More than important differences are differences in concept and how the information is displayed on the platform. Both are very similar in performance, perhaps most significantly the route navigation of the Garmin, or that the Polar allows multisport and open water swimming profiles.

  21. Another excellent analysis. Congratulations.
    Due to several fasciitis I am a sporadic runner (1-2 sessions per week of 10K, zero mountain). Since about a year ago, I have changed it for a lot of cross training work in the gym (4-5 sessions per week), which I also like to record.
    I know that all sports watches have their forte in outdoor activities, but in these conditions, what would you recommend, between the 245M, 645M, and Vivoactive 3 Music? The last one is a little bit backwards that has very few Firstbeat algorithms to which I'm already used to.
    By the way, my intention in the medium term is to reduce the load of cross-training and get back to running. Thank you!

    1. If your goal in a while is to spend more time and training in running then I think it is better to go directly to FR245. Today the Vivoactive 3 is going to be perfectly valid for what you are doing right now, but with that goal in mind FR245 will be a better option in the future.

  22. Gracias Eduardo. Al final creo que subiré un peldaño más y me lanzaré a por el 645M. La razón no es otra que el diseño, acabo de ver los tres en un corte inglés y el 645, con su bisel de acero, tiene mucha mejor presencia que el 245. Al final son relojes que acabas llevando todos los días y qué menos que te guste verlo! Y de paso podré trackear mis jornadas de esquí el próximo invierno 😉

  23. How about Eduardo.

    Joppa, my boy, thank you for these thorough studies.

    You've done 2 huge rvw's on the Vantage M and this Garmin 245. I have a Vivoactive 3 and I'd like to take a jump. I'm cycling and I'm starting to run, I think that's why I'm encouraging myself to take this jump to a watch that offers me more metrics. All this stuff about recovery, load level, etc., catches my attention and I like it.

    I bought the other day the Vantage M, but after reading this article I'm hesitating to change it. I haven't even opened the box yet :).

    Do you recommend I do it, or will I like the Vantage? I don't rule out pulling a little higher if you think it's worth it, type FR645.

    As a tip, I don't think I'll ever do triathlon or even compete in popular races (I'm not into that).

    I leave you open to recommend any brand, I propose these 2 because I have the feeling that they are the ones who are really distributing the toast.

    Thank you very much in advance and give hard to this that I see a quality distance from the rest very big and you will go of fable.

    1. Thank you Jose Luis.

      As for your doubt, I would recommend Garmin, because you are already on the platform and that's where you have your training, what you already know, etc. The change will be less traumatic.

      Of course, where Polar is working very well is in the training control and rest analysis updates that will come at the end of the year. These are very good things, but if you only do sport for fun you won't get much out of it.

  24. Hi, Eduardo.

    I'm hesitant to change the Vantage M to garmin 245.
    My intention is also to get a stryd.
    Do you think that the combination Vantage M + stryd is enough for our amateur training? Do you think that the 245 or 645 + stryd would bring me more than the Vantage M?
    I usually do rhythm change workouts, shootings and pool sessions.

    Thank you!

    1. If the main use is Stryd I think the Polar is a better choice. The Vantage M has direct support for running power, with specific data fields and in the future with possibilities like zone blocking or, hopefully, for use in training as another available zone to use. All that is not present in Garmin, depending exclusively on the Connect IQ applications. That is something to keep in mind.

      If Stryd is going to be used as an additional metric but without basing the training purely on it, then what Garmin has to offer is sufficient. As far as input is concerned, especially route navigation or the possibility of music, but it should also not be forgotten that today the GPS of the FR245 is giving better results.

      And in favour of the Polar you should not forget that there is TrainingLoad Pro, along with the sleep and rest analysis metrics that are about to be released on the Ignite.

      In short, with either you have the basics covered, but you must decide which of the extra possibilities you are more inclined to.

  25. IMPRESSIVE ANALYSIS,... I want to ask you a question as an expert,... I have the 735xt with which although I am happy (it has less resolution) and it seems more old-fashioned,... although I wear it all day, sportively it is only for running.
    Do you think it's worth changing for this 245?
    many thanks

    1. Thank you, Paul.
      Tendrás las métricas de entrenamiento, que es algo que no está presente en el 735XT. Además del nuevo hardware (chipset GNSS y sensor de pulso óptico) y evidentemente todo en un reloj con más «empaque» ya que en eso mejora bastante a la generación anterior. Quizás es donde más puedes ganar, en la imagen del reloj en el día a día.

  26. Is there a specific heart rate monitor or at least with applications for canoeing?

  27. Good morning, Eduardo,

    For swimming the device is compatible with HRM swim? In the product specifications of your website it is not indicated.

    Greetings and thank you.

  28. Hi, Eduardo.
    I usually practice mountain biking, hiking, weights and a bit of running. What watch would you recommend? 245 would be too much for me?
    Greetings and thanks for your page

  29. Muy buenos y detallados análisis de relojes deportivos gps he estado leyendo en tu blog, al que he llegado ante la necesidad de comprar uno. Vengo del Polar M400 (4 años y medio me ha durado dado que no lo uso mucho y el fallo al final no ha sido de batería sino del minipuerto usb con el que se recarga, el cual me dio problemas desde el primer día; le daban una vida de batería de unos 3 años / 300 recargas y creo que al mío le quedaba, según mi uso (carga +- 1 vez/semana, para año-año y medio): la verdad es que no me gustó nunca su medición en comparación a otros runners con Garmin y eso que en su época, al comprarlo, era («decían») de lo mejorcito.
    Pues bien, ahora salvo arreglo, ha pasado a mejor vida y siendo el uso que le voy a dar el de «runner», mi opción durante este tiempo siempre fue el Garmin 235… pero ante la salida de nuevos modelos, dudé si tal modelo de 2015 o el Vivoactive 3, unos 26 años más «joven» al ofrecer prácticamente lo mismo y nuevas funcionalidades (aunque sean de smartwatch, que no es el uso que le daré) por unos 20 euros más. Ahora que está el 245, evidentemente me decantaría por él pero es algo caro para mi presupuesto. Ante la salida del «Stratos» 3 y ve el feedback del mismo (si es tan decente como lo pintan el medidor de pulsera y otras funciones) te querría preguntar cual me recomiendas para el uso que le daré, y ante la balanza de precio del Stratos 3 por unos 140 euros frente a los 220 euros del 245 (precio estipulados para el BlackFriday que es cuando compraré el reloj ya que no es bien de primera necesidad y este tiempo puedo valerme de un reloj digital convencional). En cualquier caso sé que la mejoría respecto a mi modelo anterior (y dado que no sigo exhaustivamente las funcionalidades y posibilidades del mismo) será considerable (tengo banda pectoral para medición de pulso que apenas he usado debido a los roces que me producía, pero cualquiera de los 2 modelos (Garmin 235 o Xiaomi Sports Watch (conocido como Stratos 3) pienso que me valdría vía Bluetooth, ¿cierto?)

    1. Between the 245 and the Stratos 3, for running, the Garmin is clearly a better choice. I have to try the new one, but I don't think the changes are important with respect to the Stratos.

      In a few days it will also be the presentation of the Vivoactive 4

  30. Thank you, Eduardo.
    Excellent article.
    I've already ordered the Garmin Forerunner 245. I mainly decided on it because of the improved wrist sensor. I bought the vivoactive 3 and returned it precisely because the measurements were very inaccurate. I have the Garmin Forerunner 225 and as hard to believe as it seems it has always given me quite accurate pulse measurements, both at rest and during training. I rarely use the chest strap. Less than that I'm not going to order. I hope we got it right this time.

  31. Hello, Eduardo, greetings from Mexico.
    I live in a wooded and mountainous area, I have just started to run, I practiced road cycling for a long time but time is not enough for me anymore. I am very interested in the functionality of being guided in my training as well as knowing if I need to rest or train harder, I am a little worried about the GPS coverage in this kind of area where I live. I have the possibility to acquire the 245 Music and the 645 Music, both for the same price. Which one do you advise me to acquire, I am very hesitant, help!

    1. Si lo que te preocupa es la recepción de satélite, en ambos casos lo veo similar. Ninguno de los dos es superior al otro. El chipset de Sony lo ha tenido complicado desde el principio, pero no parece que a Garmin le haya costado mucho trabajo «domarlo». En configuración GPS+GLONASS lo he visto perfecto en el 245. No es algo que me preocupe.

      In your case I think the decisive factor to consider is the barometric altimeter. You live in a mountain area and I guess you will end up doing a lot of slopes. If you want to know data on altitude ascended DURING TRAINING, only FR645 will give you that information. If you don't worry about it during training and you will only consult it in the application after synchronizing, then it is not something you should take into account.

    1. No, 245 doesn't have the lactate threshold calculation. These are the ones that support it:

      Fenix 3 / Fenix 5 / Fenix 5 Plus / Fenix 6
      Forerunner 645 / 735XT / 935 / 945

  32. Hi, Eduardo.
    After reading all your (magnificent) analyses, I have the same kind of doubts as the others. I am already one age (52) and after several knee and neck injuries, I have had to give up mountain biking and have found in sport walking my sport. As there is no impact, the knees do not suffer. I do about 35 km a week, including series, and a couple of days of gym, including swimming pool (breaststroke). I also like to go out in the mountains for simple routes.
    Obviously I love the Fenix, but I'm out of price, and I was going to buy a FR235, but it has coincided with the release of the new range and I do not know what to do. Right now the option that throws me more is a FR 735 that I find the same price as the Vivoactive 3, and that is more complete and compatible with the app of Wikiloc. The FR 245 and the Vivoactive4 have sown the doubt, but worth 100 euros more, which is no small thing, and if I'm going to get into that, for a little more is the Fenix5. A without living.
    Is it advisable to take advantage of the prices of the previous range and get a 735? Does it fit my profile?
    If not, what do you recommend?

    1. With the 735XT you have the problem of the lack of altimeter. If you are going to do mountain you will be grateful to have complete data of altitude. With the FR245 you are in the same situation. The Vivoactive 3 would be a good option, but what it lacks is the navigation of routes... So if you want something that fits you with the use that you are going to give it... the Phoenix 5 or the FR935.

  33. Eduardo, excellent analysis, very useful. And now the question: has come out the Vivoactive 4 that surely soon will analyze. My doubt is that being even a little cheaper than 245, has the same or even better chances than this. To start with aesthetically has better packaging, more wearable, and then has almost everything of 245, including music, and NFC (which I do not really care because I will not use).
    For someone who runs mostly on the flat, who doesn't do triathlon or practically bike, what would you say is the best option? Thank you.

    1. Overall, both are very, very similar. You have to go into detail to see which one you're looking for. For example, the VA4 doesn't have the training load metrics or navigation that the 245 does. But it does have an altimeter and guided training.

      In short, simply by comparing the Firstbeat functions of the two models you will quickly see the differences:

      Forerunner 245:
      Vivoactive 4:

      I don't know how wrong Garmin is in launching products, because as you've already noticed, it's not easy to choose the one you need.

      As for the test, I'm up against the Fenix 6 and then the VA4 and Venu will come.

  34. Thank you very much Eduardo for your magnificent analysis and congratulations on your work.
    Regularly popular runner of half and marathons.
    I train four days a week.
    Currently Polar V800 (I do not practice triathlon) and I want to change.
    I hesitate between the Polar Vantage M, the Garmin FR 245 and Garmin FR 645.
    Priorities: heart rate, programming of series and interval training, GPS.
    What would be your choice?
    Thank you again.

    1. Being used to Polar (and having all your workouts on the platform), that makes you more inclined towards the Polar. You know the series training schedule and you know what it is. However, the Polar GPS still needs a little work, it's a little worse than the Garmin. And as for the optical sensor, lately I'm seeing the best results with the new Garmin sensors.

  35. Hi, Eduardo. Excellent analysis. I'd like to ask you a question, see if you can help me because I'm a bit hesitant and you have a wider knowledge of the range.

    Soy deportista multideporte aunque estoy bastante enfocado al cardio. Suelo hacer deporte sobre todo en INTERIORES (un gimnasio). Hago carrera en cinta (aunque quiero salir por la calle), spinning, remo, natación y pesas. Estas 5 cosas son las que más o menos conforman mi rutina. Entreno 5-6 días a la semana a un nivel medio. No me planteo maratones ni triatlones por el momento, ya que estoy haciendo «rodaje» por mi cuenta y cogiendo fondo.

    I had thought about this model, I don't know how you will see it for what I want. I had also thought about the Polar Ignite and the Vivoactive 4 but the touch screen thing makes me go back. I prefer buttons. What sport profiles does this watch have? Can you add more with in Polar?

    Thank you very much for your help!

    1. The Vivoactive 4 is the one that will best suit your use, especially if you row frequently (because it has a specific sports profile).

      The 245 for gym has strength, cardio, elliptical, stairs and yoga.

      As for the Vivoactive 4 I am about to publish the full analysis, it will probably be available tomorrow.

      1. Muchas gracias por la respuesta. Lo que pasa es que suelo hacerlo todo en interiores, por lo que el remo, seguramente no haya especificado bien, también lo hago indoor, en las máquinas estas típicas de gimnasio, y suele ser de calentamiento, entre 10 y 30 minutos. ¿El perfil genérico de «cardio» valdría para abarcar el remo (o cualquier otro que no tenga su propio perfil (step, body pump, spinning…)? Atendiendo a la fiabilidad tiempo/pulsaciones/calorías. Es lo que más me interesa, ya que las métricas avanzadas (en general) no me interesan mucho. Valoro más que sea fiable en el pulsómetro y en las calorías quemadas.

        Does the heart rate monitor work in swimming on this 245? I have seen that on the Vivoactive 4, EL 945 and the Ignite Polar it does work.

        Thanks for your help!

        1. Yeah, in cardio you could get it all in without a problem.

          For that kind of use you are going to do with the Vivoactive 4 you are going to be more satisfied, because you also have the barometric altimeter and Garmin Pay, and if you are not going to use the racing or navigation metrics...

          The heart rate monitor is the same. And yes, in 245 it can be activated in swimming.

  36. Hi, I don't know if it happens to anyone else, but the photos don't load on my iPad with any browser

    1. Rare Alberto... I've tried several devices, several browsers and I've had no problem. Are you still having problems with images? Maybe it's detecting you as a desktop and trying to show you webp files...

  37. Hello
    How can I fix it?
    I tried to show it as a mobile site and it doesn't work and in several iPad browsers, on a laptop it looks good
    Thank you

    1. It's very rare because in all the devices I've tried (iPad included) I haven't had any problem. Try opening the page in incognito mode and loading from there, in case you have problems with cached files.

  38. Hi, Eduardo.
    As I see that you are kind enough to answer your readers' questions, I dare to go this way with mine, after having studied your website well.
    Busco un reloj multideporte, básicamente para correr (1-2 veces por semana 5-10Km), nadar y entrenamiento funcional en casa o similar (básicamente ejercicios de repeticiones con el propio cuerpo y no con pesas, yoga o crossfit). No necesito funciones de Smartwatch o música y tampoco mil datos para correr, pero sí que tenga todas las funciones de Fitness Tracker y que tenga perfiles decentes para natación y entrenamiento funcional o como se llame en cada reloj. También me interesaría controlar el pulso en piscina (sin cinta para el pecho), ya que me parece que la cosa a veces se acelera mucho, aunque leo que los sensores ópticos no van tan bien en el agua, así que según que me digas quizás tendría que renunciar e eso. Con el criterio del pulso en piscina e ignorando las gamas más altas veo que la elección se reduce a Polar Vantage M, Forerunner 245 o el Vivoactive 4. Correcto? Se me ha pasado algún modelo que podría tener también en cuenta? Lo de «pisos subidos» sólo lo tiene el Vivoactive 4, pero tampoco es un must. Cual de ellos tendría los perfiles deportivos más adecuados para mí? Si renuncio a la función de pulso en piscina, qué modelo me recomendarías que respetara los otros criterios? Quizás Vivoactive 3 ahora que está bien de precio?
    Thank you very much for your ideas and congratulations on the website.

    1. Yeah, you've basically narrowed it down pretty well.

      The pulse in the pool doesn't obsess you much either because it's not that precise. It's fine for an approximation of how intense you've been swimming, but not for more thorough analysis.

      I think the Vivoactive is the one you'll be most comfortable with. Both the FR245 and the Vantage M have options that I don't think you're going to get.

      1. Thanks for the quick answer, Eduardo.
        I see I've done my homework well and I understand everything you explain in your analysis.
        I was finally able to test the models in the shop and I have discarded the Vantage M because of its size, it is a bit of a humbug. Something more comfortable is needed if you want to wear it 24 hours a day and use the functions of fitness tracker, sleep monitor, etc. In that sense I think the FR245 is not only the prettiest but also the most suitable size. I would have options that perhaps I do not need, right, but the same goes for the Vivoactive, whose smartwatch or music functions I would not use. You always end up paying for functions that you do not need. However, I have not discarded the Vivoactive. They are also nice and the 4S can be more comfortable, although I doubt a little also because of the touch screen. It will depend on the price. We will see...

  39. Hi Edu, congratulations for the piece of analysis you've done. One question, with FR245 MUSIC, if I don't use music, can I use the 4GB to store the workouts, watchfaces, etc.? Thanks.

    1. Yes, perfectly. But come on, that's like having a 10,000 sq. m. shed to store your silverware and dishes...

      If you only want to save workouts, applications and so on, with the normal FR245 memory you have more than enough.

  40. Hello, good evening.
    The first thing is to thank you for all the comments.
    I'm hesitating between the M430 fleece, Garmin Vivoactive 3 or Garmin Forerunner 235, which would you advise?
    I go out for a run 3 days a week for about 1 hour a day.

    Greetings and thanks in advance

    1. If you simply run without competitive goals or need interval training, the Vivoactive 3 is the one you will like best.

  41. Good one.

    First of all, thanks for the piece of analysis.

    And the second thing is perhaps a bit silly: To use Spotify in the watch I need to carry my mobile with me, or do I need to have the Spoti premium? I've never had a watch like this and I don't know how it works.

    Finally, I'd use it for police mileage training. You see this as a good option for that, or would you recommend another one?

    Thank you and a greeting!

    1. Thank you, Javier.

      With 245 Music you don't need to have your phone with you as the music is on the clock, but you do need a premium Spotify account (or from Amazon).

      You have the possibility to schedule advanced trainings, so to prepare the kilometer test you go perfect.

  42. I'm thinking about buying one of them, taking advantage of the discount it has now in RunnerInn (280 euros for the music version), but I have a doubt:

    - Although there are different sport profiles, I understand that it is a watch more focused on running. What I do most currently is swimming (about 8-10 hours per week) and maybe I get 1 or 2 hours of dry exercise (which can be cycling, weights or some treadmill or walking, where I would use music). Is it an appropriate model for swimming considering this, that the 80-90% of my activity is in water?

    - I have seen that they have released the Garmin Swim 2 but I see that, for practical purposes, it is worth almost the same as this 245 with music (if you take the model without music it is even cheaper) because the Swim 2 hasn't received any important discount yet. Looking at the specifications I see that it is more complete in the swimming metrics (that I don't need something very advanced either), but it loses the music option and the multisport profiles like weights or indoor running and cycling. It doesn't seem like a good option right now unless you tell me otherwise.

    - I think 280 euros is a good price in RunnerIn but of course, we are in the dates that we are. Do you think it will go down even more in Black Friday?

    Thank you very much for your help.

    1. Yes, you can use it for swimming just like the Garmin Swim 2. There are only two main differences: there is no support for swimming in open water and it is not compatible with the HRM-Swim pulse sensor (but you can use the optical pulse sensor).

      I think that the Swim 2 has, at the moment, a rather high price, especially considering that part of the FR45 is a more economical model. Garmin needs to lower the price if they want to make it an interesting model.

      I have no confidence that the Forerunner 245 will be part of this year's Black Friday sales. It's a new model this year and it's selling very well, so there's not much point in lowering it. I may be wrong... but if I had to bet, my money would be on no sales for that model.

  43. Hi! I'm looking at a watch that can be used for running on asphalt and sometimes in the mountains. I would also do some mountain route hiking mode. Therefore, in addition to the GPS functions, rhythm, keystrokes, etc. etc, I would like you to be able to use it to follow a route well (so far, either I know the way or when I go hiking I have to go with my mobile phone in hand and Wikiloc to look). Do you think this watch can be used for that? If so, buy it safely, because in running functions it convinces me a lot. Thank you very much for the work!!!

    1. Yes, with the FR245 you will have no problem. The only thing you have to evaluate is if you do a lot of mountain, choose a model that has a barometric altimeter, if you are interested in having the data of ascent and descent in real time.

  44. Good night!
    I would like to know what watch pod would advise me. After years of stopping I have returned to half marathons and my Polar M400 is obviously obsolete. I am looking for a watch only for running (except for some hiking route)
    I started out looking at the Garmin 235 but paying about 170/190 euros for a watch that's several years old I don't know...
    Then I focused on the Garmin 735 but I see that it is mostly for triathletes.
    And finally I have seen the Garmin 245 for a price that ranges between 230/250 ,maybe this week with the black friday I will find some more bargains. In most of the sites it is in 299
    What would you recommend? Any other models I haven't mentioned?
    I want it almost exclusively for running, that it has a good GPS, that it measures you acceptably the FC, that it plans trainings I imagine that it would also come well...
    Thank you and a greeting

  45. Thanks Eduardo! From what I see the prices are similar. Between the two, which one would you choose? Which one do you think is more complete? I do half marathons and the training is also on asphalt
    Thank you for everything.

    1. It is a very personal decision because both have very similar performances. The FR245 stands out in having better finish and navigation, while the Polar does it in platform and in all the performances it has received after its last update.

      But in your case I think the fact that I'm already at Polar makes me more inclined towards the Vantage.

  46. I'm hesitating between the 735 and 245 or the vivoactive4. I just need it for running, with training series, rhythms,... and I usually do races and training by mountain. Can you help me in the main differences? Thank you very much for all the analysis, in what I can I will help you so you can continue.

    1. Of those three, rule out the 735... it has nothing to do with any of the other two.

      In the Garmin Vivoactive 4 test opinion section hablo específicamente de las diferencias entre ambos. El 245 está más orientado a corredores, mientras que el Vivoactive 4 es un reloj más «lifestyle» (lo cual no quiere decir que no sirva perfectamente para correr).

      But I understand that if you do a lot of varied training and train by mountain, you're going to make use of training metrics and navigation, so I think it's the right choice for you.

  47. Good morning
    Great review
    Since I'm making progress on this running thing, I've decided to change the stratos to a garmin.
    The use I'm going to make of it is mainly for running, basically on asphalt, and some day for mountain and hiking, even swimming in a pool. I basically do one or two days of gymnastics (bodypump or functional training), and three or four days of running.

    I'm looking at the 645, the vivoactive and this 245 and the truth is that, in the end, such comprehensive reviews end up making you more indecisive.

    I value the music. I don't make it the main theme because in the end I've gotten used to going out with another device, but I find it interesting.
    I'm interested in metrics, but I don't know how much use I can make of them. I'm a pretty normal runner, so I don't know how much use I can make of them either. I'm hooked and I want to improve, that's clear.

    I've seen an offer of the 645 without music at a good price, even a little cheaper than the 245 WITH music.

    Which one do you recommend?

    1. Thank you, Jon.

      If you don't do a lot of mountain and it's just something sporadic, I don't consider the altimeter to be a decisive factor, which is the main difference between 245 and 645. But if you value having music, I would look for a watch that includes it.

      Maybe the decision would be between 245 and the Vivoactive 4. I don't know if you've seen the analysis of the Vivoactive 4, but in the opinion section I'm pretty clear on how you can approach the choice.

      1. The band is recommended for interval and series training, and is essential for cycling. It depends a lot on what your goal is in the series, if it is rhythm or heart rate. If it is rhythm or time with the optical sensor is sufficient; if the goal is a range of pulses then sensor in the chest.

        And like I said, if you're planning on cycling, it's mandatory.

  48. Hey, thanks for the article.

    You don't say anything about how long it takes to get the gps signal. I come from Forerunner 410, and this is usually a pretty common problem.
    On the other hand, I have the HRM band, but I want to buy something for the race metrics. Is it worth renewing it for the HRM-Run (which is almost sold out in all stores), or buying a Garmin Pod?

    Thank you very much!

    1. For many years now, this has no longer been a problem: the clocks now download the satellite prediction at each synchronization and the signal is obtained in a matter of seconds, both in the FR245 and in any other current model.

      1. Great, that's a relief.

        About the HRM-Run band, which is sold out everywhere, would you recommend it? Or better yet, the running pod?
        I have an old hrm band.


        1. On Amazon The HRM-Run is totally recommendable, in addition this year the HRM-Pro will arrive, which will be like the HRM-Tri (with race metrics and memory, but also Bluetooth like the HRM-Dual). I am more in favor of the pulse sensor because the clip is in permanent risk of going to the washing machine with the pants.

          1. hahahaha That and that I forget before leaving I had thought about it too.
            That's probably why it's sold out at the other stores. You know when the pro comes out?

            Thanks again!

  49. Hello,

    I'd like to know if anyone else has experienced the following problem at 245 music.

    I have an imitation airpod headset and the linking and playback of music is done without any problem, but at a very high volume and no matter how much I press the volume adjustment button it does not respond, which makes it impossible for me to listen to the music as it is very annoying.

    Has anyone ever had a similar problem?

    Thank you

    1. Yes, I've also had problems with Huawei Freepods headphones where they only allow playback at maximum volume.

    1. No, it's a matter of drivers and compatibility... it can only be solved by updating the headset (which won't come) or the clock firmware (which also can't test absolutely all headphones on the market)

  50. I would like to take this opportunity to ask another question, because no matter how much I look at the instruction manual, I can't find the key. Sorry if this is not the most appropriate way.

    I come from the Polar brand and with my previous heart rate monitor I had the automatic laps (1km) and then I had the possibility to do manual laps by pressing the "Back" button. Later, when I downloaded the training in the Polar application I could see the information of both the automatic 1km laps and the manual laps that I had set.
    Is this option not possible on the Garmin 245?
    Actualmente tengo configurado el autolap a 1km para que en los rodajes me de información de cada km, pero me gustaría que en determinados momentos yo pudiera marcar las vueltas de manera manual y ver luego esa información en la aplicación Connect. Por lo que había leído pensé que con pulsar el botón «Back» cuando yo quisiera sería suficiente, pero lo probé en el entrenamiento de ayer y no lo conseguí:
    Rodé durante 25′ y pulsé el botón «Back» para comenzar a realizar cambios de ritmo de 5′. La idea era pulsar el botón «Back» cada vez que completara esos 5′ pero para sorpresa mía, al llegar a 1km la vuelta se reiniciaba y por tanto me fue imposible completar los 5′.

    1. No, the laps work differently in Garmin and Polar. To do it the way you want, you'll have to turn off the automatic laps because they're not separate.

  51. It's a shame, because the Garmin 410 had it exactly as David says. It looks like it's been ruined by the new models.

  52. I'm a newbie and I just bought a 245. I go out for a run and my GPS is not easily activated. I can't turn it green even if I stand still. Other times it activates after fifteen minutes suddenly. I would like you to tell me the steps to follow in case I'm doing something wrong

    1. You must be in an open place for the signal to be obtained correctly. The first time always needs a little more time, but usually it is a matter of seconds.

      It is important not to start running until you have set the signal, otherwise it will take much longer, like those 15 minutes you indicate.

  53. 15 min seems too long. It usually takes me 2-3 min. Sometimes 15s, sometimes 5min.
    It gets a little better if you go for a run with your cell phone connected to the clock, but it's not magic either.
    Follow the advice: open space, don't move until he locates you, let him look for the signal a few minutes before he starts running (at home, for example).
    I read that there is a system called SIRF Instant Fix that I don't know if it can be activated in the garmin. It records the satellites of your last position, so if you go out for another run from a nearby point, it locates you faster.

    But 15min still seems a lot to me...

    1. Currently all clocks do GPS location cache download with every synchronization. This is part of the reason why satellite fix time has been greatly improved.

      1. So with the new 245, with the phone linked, still, about 8m from the nearest building and in a wide street (30m), it usually takes me 2-3 min.
        Without the phone attached, it doesn't get much worse.

        Not at all for just a few seconds like you say. Does it ring a bell if it's a mistake?

  54. So with the new 245, with the phone linked, still, about 8m from the nearest building and in a wide street (30m), it usually takes me 2-3 min.
    Without the phone attached, it doesn't get much worse.

    Not at all for just a few seconds like you say. Does it ring a bell if it's a mistake?

    1. Whether the phone is connected at the time, the download occurs when there is a synchronization.

      It depends a lot on the geographical area, when the last training was done, how the buildings are (height, elements that bounce the signal, etc)... There is no absolute value.

    1. Funny... I suppose it will only affect some specific cases, because I usually go out with the 945 when I'm testing other models and I don't have any problem when receiving a signal.

  55. Hi!

    Which bike (mtb and road) and running clock: the 245 or the 735xt? Or do you recommend another model?

    Thank you!

    1. For that kind of use the FR245 is a good choice, and better than the 735XT because it is already quite old in comparison.

  56. Acabo de adquirir el FR245music. Vengo de un 735xt en el tenía muchos problemas con el sensor óptico del pulso.
    Las primeras impresiones del reloj son muy buenas. El pulsómetro óptico es mucho más fiable que el del 735xt.
    Con lo que me he llevado una decepción es con el apartado música. Por un lado, después de invertir 50€ en la versión musical, veo que si pongo la música en el reloj, no puedo controlar el volumen de los auriculares (unos Xiaomi). Por otro lado, al poner la música desde el móvil, el reloj no permite ningún tipo de control del reproductor, cosa que si que podía hacer con el 735xt.
    En fin, vender un reloj con el extra de la música y que no sea funcional a mi me parece una vergüenza.

    1. Que el control de volumen de los auriculares no funcione no es cosa de Garmin, es cosa de Xiaomi y en general de cómo se implementan los estándares no estándares de Bluetooth.

      Para controlar la música del reloj simplemente tienes que cambiar el proveedor de música en el reloj y seleccionar el teléfono.

    Me lo compré a principios del enero de 2020 y a mediados de febrero, habiéndolo puesto a prueba con cerca de 40 actividades de gran intensidad (carrera, marcha, natación y ciclismo) he podido comprobar que arroja errores en los resultados de distancia recorrida y de pulsometría que oscilan entre el 10% y el 25 %,
    Por ejemplo, aun día nadé 2.000 metros y el reloj me dijo que había nadado 2.500 metros. Por otro lado, recorriendo el mismo desde mi casa al trabajo, unas veces me dice que son 4,2 km y otras 5,3 km. En otra ocasión, lo testé con otro reloj que también me puse, y el garmin arrojaba cerca de un 10% menos de pulsaciones, es decir, que a lo mejor me use en 175 pulsaciones y el reloj me decía que estaba en 157 (y en esos umbrales esa diferencia es muy importante de cara a prevenir lesiones de corazón). Por último, a veces, a la hora de medir la saturación de oxígeno me arroja error.
    Ante este cúmulo de fallos fui al establecimiento donde lo compré y llegaron a decirme que a ellos les pasaba lo mismo (alucinante) y que si lo mandaban a fábrica, lo más seguro es que me lo devolvieran al cabo de un mes diciéndome que no le pasaba nada.
    Mi pareja se ha comprado otro garmin cuyo modelo no recuerdo ahora mismo, y me da la sensación de que tiene los mismos problemas, por lo que deduzco que el software de la marca no es bueno.
    Por favor, no hagan más caso a este bloguero, dado que sus comentarios distan mucho de la realidad.

    1. Tienes toda la razón, que nadie me haga caso (aunque aporto pruebas de todo lo que digo y comparo), pero sin embargo por supuesto que se haga caso a los mensajes que no aportan ningún motivo técnico ni nada más allá de acusar a nadie de que sus comentarios distan de la realidad.

      Me vas a perdonar, pero eres el claro ejemplo del «hablar sin tener ni idea»

  58. Hola. He visto que de todos los Garmin que analizas, le das la máxima puntuación al forerunner 245, siendo un reloj de gama media, frente a los de gama alta que valen el doble y, supuestamente, deberían funcionar mucho mejor. ¿A qué se debe esa clasificación?. Un saludo.

    1. Las valoraciones no las hago con respecto a un baremo fijo para todos los modelos, sino para cada caso específico y segmento en el que se encuentra. No es el mismo segmento el del Fenix 6 Pro que el del FR245, ni por supuesto el precio tiene nada que ver.

      El 245 tiene una muy buena nota porque es un reloj muy completo para el segmento en el que se encuentra, y además no tiene un precio demasiado elevado.

  59. Hello,

    Tengo una duda entre el 245 o 645. Soy corredor tanto de montaña como de asfalto con una media de 60-80km. carreras de asfalto media maraton y en montaña carreras de 25-30km.

    No se si hago bien descartar el vivo active o no? de todas maneras cual me recomiendas entre el 245 y 645?


        1. en tu enlace el el music el de 282€ no esta disponible esta a partir de 326.99€.

          una duda más, el 245 tiene mejor chip gps, no? y el pulsioxiometro, no? las metricas que da el 245 son mejore que las del 645?

          Los dos tienen opcion de meter un track y seguirlo?

          245 sin music 231€ y 645 sin music 259€

          Thank you for everything!

          1. El que tiene los detalles en dorado sí está disponible.

            El 245 tiene un chip GPS con menor consumo de batería. Las métricas son las mismas, y ambos tienen seguimiento de rutas. También te digo que el altímetro barométrico sólo ha de preocuparte si vas a mirar metros acumulados durante el entrenamiento. Si eso no te preocupa entonces no es un detalle importante (

  60. Hello,

    La verdad que no voy a mirar durante el entrenamiento el desnivel, con que al final pueda tener un valor próximo ya me es suficiente, es decir si una salida es 25km con 1300m D+ que al finalizar mas o menos el reloj marque algo similar no necesito una exactitud perfecta. Tema NFC ya uso el móvil.con es

    Al final salgo a correr por placer, entreno por mi cuenta y tampoco necesito una gran cantidad de datos.

    Gracias por tu tiempo!

  61. Hola, me puedes decir que autonomía tienen el forerunner 245 y el 645, conectados a una banda de pecho por bluetooth y con gps y pulsómetro funcionando. Gracias. Un saludo.

    1. La autonomía es hasta 24 horas en el 245 y hasta 14 horas en el 645. Eso es sin usar sensores de ningún tipo. Utilizando un sensor externo, calcula un 10% de reducción aproximadamente.

  62. Muy buenas en primer lugar decir que el articulo esta de 11.Emtrando ya en materia yo vengo de un polar m430 muy trayado ya de entreno , 6 dias a la semana de 1h30 de piraguismo y algo carrera. Otrosgarming como el forerunner 645 ya se me van un poco por el tema de la banda,que por cierto el 240 seria compatible con la banda de polar h7??. Y por ultimo cual seria tu recomendacion por este rango de precio. Muchas Gracias de antemano

    1. Sí, el 245 es perfectamente compatible con el sensor H7, a través de Bluetooth.

      No obstante, si vas a hacer principalmente piragüismo te recomiendo algún otro que sí tenga perfiles de remo. Aunque en el FR245 puedes instalar alguna aplicación de Connect IQ, dado que será tu uso principal iría directamente a por esa opción.

  63. Hi, Eduardo,
    Una duda más. Entre el suunto 9 (que ha bajado de precio, 280€) el Forerunner 245, con cuál te quedarías?
    Thank you very much.

    1. Depende del uso que le vayas a dar. Para montaña prefiero el Suunto por la navegación y el tamaño de la pantalla. Para asfalto el 245 es más cómodo y tiene todo lo necesario.

  64. Hi, Eduardo,

    Tengo una duda, yo tengo un Edge 520 para salir en bici y estoy pensando en comprarme un Forerunner 245 para salir a correr. Mis estadisticas de las actividades de bici con el Edge, se sumaran a las estadísticas del Forerunner aumentando, por ejemplo, el VO2 max? No sé si me explico bien. Pero quiero saber si al utilizar un dispositivo sin medicion de VO2 como es el Edge, al sincronizarlo con el Forerunner este calculara los datos como si ubiera utilizado el Forerunner.

    Thank you very much!

    1. El VO2Max de carrera y de ciclismo son distintos, uno no afecta al otro. En cuanto al VO2Max de ciclismo necesitas un potenciómetro, sin él no se calcula.

  65. Hi, Eduardo,

    Gracias por tus análisis, al día de hoy con todas la actualizaciones recibidas en el polar vantage m (es de mi interes) como le hace frente al 245? que están dentro del mismo rango. Llevo usando ya unos 2 años el m430.


    1. Thank you, Pablo.

      Si le echas un ojo a la shopping guide, verás que recomiendo cualquiera de los dos. Ambos son buenas opciones, y depende principalmente de lo que busques. En tu caso estando en la plataforma de Polar igual te sientes más cómodo con el Vantage.

      1. Hola Eduardo, he comprado el Forerunner 245 M y te quería preguntar por la app Maps r.486 ¿Cómo va? Sirve para ver los mapas en la app nativa de Garmin o hay que verla en la original. Y en la navegación se ven todos los detalles?. Gracias de antemano.

        1. No sé a qué app te refieres. He buscado por «Maps r.486» y no encuentro nada.

          En cualquier caso, las aplicaciones de Connect IQ no se muestran en los perfiles nativos del reloj, son una aplicación independiente.

  66. Hello,

    quería saber si puedo tulizar el Garmin forerunner 245 music para natacion en el mar.


  67. Que tal amigo, saludos desde michoacán México. Te comento que recien compré un 245 music, pero se me apaga el sensor cardiaco en forma intermitente como por dos a cuatro horas y después enciende sólo, sin hacerle nada… Has sabido de fallas así o será necesario llevarlo a garantía? Gracias por tu comentario…

  68. En primer lugar felicitarte por estos análisis realizados con tanta dedicación. En segundo lugar, ¿Qué reloj me recomendarías para carrera (con entrenamiento con picos de velocidad y recuperación), que en cuanto a smartwatch se maneje relativamente bien y un buen sensor de pulso que por ejemplo me mida las pulsaciones cuando juego al Padel o realizó ejercicios de fuerza y HIIT? Creo que tanto este como el vivoactive 4 me servirían, pero espero tu consejo. Gracias!

    1. Gracias Miguel Ángel.

      Viendo que estás interesado en entrenamientos de carrera y haces un buen seguimiento, es mejor que optes por el FR245 más que por los Vivoactive, pues tienes métricas específicas para carrera que vas a poder usar.

      1. Buenos días Eduardo, se acerca mi cumple y sigo dándole vueltas al reloj. Mirando en la página de Garmin y en tu análisis diría que el 245 no tiene la opción de usarlo para seguir rutas de senderismo. ¿Cual sería el reloj que por calidad/precio mirarías?

  69. Hi, Eduardo,

    Tengo un FR245 y un 520Plus para la bicicleta, he intentando añadir el FR al 520 como sensor de Frecuencia Cardíaca y no lo he conseguido. En el 245 he activado la función Emitir Frecuencia Cardíaca pero en el 520 no lo detecta.
    No es posible vincular el reloj con el 520 como sensor de Frecuencia CArdíaca?


  70. Hola Eduardo, acabo de descubrirte y quería darte la enhorabuena por tu blog.
    Llevo un tiempo buscando un reloj y ya me había decido por el FR245 (pero la versión normal) en vez del FR235 porque entre otros tenía conexión wifi. Pero comentas que esta opción solo está disponible en la versión FR245 Music. Es la primera vez que veo esta distinción y ahora mismo me quedo con la duda… En mi caso la conexión wifi es un valor añadido por comodidad pero la diferencia de precio entre una versión y otra es considerable. Sinceramente ahora mismo no sé qué hacer. ¿Se puede sincronizar el reloj directamente con el bluetooh del móvil sin necesidad de ordenador?
    Thank you very much!

    1. Gracias Noelia.

      Efectivamente, el único que tiene WiFi es el 245 (que lo necesita para la descarga de música desde plataformas como Spotify). La versión normal no tiene WiFi.

      La sincronización por Bluetooth con el teléfono está presente en todos los modelos de Garmin, así que no tienes problema. En cuanto el reloj está en rango del teléfono sincroniza todos los entrenamientos, no es necesario que lo conectes al ordenador (ni siquiera para actualizar, también lo hará por Bluetooth).

      Echa un vistazo a las mejores ofertas de Black Friday, ese post es específico del FR245.

  71. Felicitaciones por tu blog. Muy ilustrativo para quienes nos gusta el deporte y la tecnología. Sólo quería contaros que se me ha dañado el cable cargador de mi TomTom Spark 3 (4 años) y he aprovechado las ofertas para cambiarlo por el FR 245, todo pinta muy bien, pero quería anotar que en los mismos recorridos urbanos el FR 245 no pilla bien una sola calle, parece un gps borrachín. En comparación, el Spark3 marcaba las rutas con fidelidad. He probado las combinaciones de GPS y grabación pero no he logrado un track GPS decente. No se cuál será el problema.

  72. Hola lo primero gracias por tu blog, aclara mucho las características. Aún así aún dudo, tengo un amazfit stratos 2, y tengo oportunidad ahora de mejorarlo, pero no se si dar el salto hasta el 945 del cual casi no hay ofertas o con un 245 me valdría, hablo de los garmin ya que en la bici uso un edge antiguo y parece que me es más amigable las aplicaciones garmin.
    Dudo también en la navegación de ambos, no se si podría usar alguno de los dos en la bici para seguir tracks que es lo que hago con mi edge touring plus a día de hoy, de esta forma unificaria reloj para correr y bici que es lo que hago, correr mayoria asfalto pero también vamos haciendo algo se trail de ahí que me interese también poder seguir algún track.
    A salute.

    1. Thank you, Javier.

      Si le das importancia a la navegación sin duda el FR945 es mejor opción por todas las posibilidades que le dan los mapas. La navegación del 245 es básica, puedes cargar una ruta pero es simple.

      1. Hola Eduardo, gracias por la respuesta, el garmin fenix 5 plus esta de oferta, merece la pena por 419?

          1. Y por ultimo veo el 6S PRO, que por tamaño me iria bien (tengo muñeca de 16) pero se sube 100 euros mas, aparte de alguna funcion extra, ¿es mas resistente que el 945? al querer usarlo tambien en la MTB no se si habra diferencia o es solo estetica con el bisel y caja metalica.

          2. Resistencia al uso es lo mismo, simplemente los materiales son mejores en cuanto a tacto e imagen (el 945 es de plástico). Pero en un uso sin golpes, que es lo que queremos todos, la resistencia es la misma.

  73. Hola, bue día. Primero quiero decir que es un artículo excelente, muy detallado sobre las características del Garmin, ideal para realizar un correcto análisis y poderlo comparar con tus demás opciones. En segundo, ¿Qué tanto debería dudar la batería? Es que he comprado este forerunner 245 pero de uso, supuestamente se usó 2 veces, y aunque ahora que lo he recibido probablemente fueron más usos, se ve bien cuidado y no demasiados usos. Sin embargo, lo que no me deja dormir tranquilo es la batería. Te pongo en contexto: lo cargue el sábado por la noche al 100, el domingo temprano realiza una carrera de 1 hora y 5 minutos, tiene activado el seguimiento de actividad, pasos, FC y oximetría para el sueño, y hoy, martes a las 6 de la tarde tiene el 35%, ¿Es normal en este modelo por las funciones activadas? O ¿Tiene algún problema la batería? Espero me puedas contestar pronto, pues aún puedo devolverlo.

  74. Buenas, una pregunta, las indicaciones de audio (tiempo – ritmo vuelta ) se reproducen sin necesidad del móvil, ¿también las indicaciones de ruta? funcionan bien?

    Thank you

  75. Hi, Eduardo,
    Para un uso de 40% caminata y un 60% de senderismo o trail, ¿con qué modelo te quedarías? Estoy entre el Instinct (por precio), 245 o 645.
    No me gustaría pagar más por algo que no me ofrece muchas más prestaciones a cambio. Podría renunciar al altímetro barométrico. Valoro positivamente la autonomía y la obtención de métricas realistas. ¿Cuál elegirías y por qué?
    Thank you very much.

    1. Hola Miguel.
      Creo que con ese tipo de uso encajas perfectamente en el usuario tipo del Garmin Instinct. En cuanto a GPS y demás funciones es igual que el 245, lo único que no tendrás son las métricas de entrenamiento pero que con los deportes que practicas, tampoco creo que vayas a necesitar…

      1. Gracias por tu rápida respuesta.
        He leído tu análisis sobre el Instinct. A pesar de ser un reloj asombroso, me sigue quedando esa sensación de reloj «cutre» al ser en blanco y negro. Por lo demás, aúna todo lo que necesito.
        He descartado el 245 al no tener altímetro barométrico.
        La otra opción que comentaba, el 645, también me gusta mucho. Lo que menos quizás la menor autonomía y su bísel en color plata (parece un poco chinada), aunque otra opción sería comprarlo con bísel oscuro.
        ¿Crees que se me escapa algún modelo en este rango de precios que podría ser interesante para montaña? EL 735XT? O está ya muy desfasado?

          1. Hola Edu,
            Finalmente he comprado el 645 Music aprovechando el precio en Wiggle (238€ en color pizarra), espero no haberme equivocado, porque he dudado entre este y el 245 Music por ser más actual. Por cierto, he utilizado tu link para comprarlo, espero haberlo hecho bien.
            Un saludo y gracias por la ayuda que brindas.

          2. ¡Gracias Miguel por apoyar la web!

            Mientras tengas claras las diferencias entre ambos modelos y cuál es el que se ajusta mejor a tus necesidades, seguro que no te equivocas.

  76. Hola, estoy dudando entre comprar este FR245 o el Coros Pace 2. Llevo un tiempo corriendo con mi Galaxy Active (básicamente por asfalto, por lo que a la ausencia de Altímetro no le doy mucha importancia) y aunque creo que el Coros Pace 2 es mejor reloj en general (además de más barato) por lo que he leído, para mi es muy importante el tema de la música (tendría que usar si no mi actual Galaxy Active para llevar mi música) y no se si le sacaría mucho rendimiento a los extras del Coros Pace 2 como la potencia para entrenar.

    Mi principal duda es si hay alguna fecha estimada para la renovación del FR245 que ya lleva casi 2 años en el mercado, por saber si merece la pena esperar o intentar pillarlo ya (ahora mismo el precio más barato que veo es de 255€ que creo está bastante bien).

    Muchísimas gracias, la página es de 10!

    1. Thank you, Pablo.

      Si para ti el hecho de contar con reproducción de música es importante entonces no lo dudes, el FR245 mejor que el COROS (también tiene mejor plataforma). En cuanto a sustituto, de momento no hay nada previsto. Mi impresión es que la situación con la pandemia ha ralentizado todos los lanzamientos, de hecho en el tiempo que llevamos sólo se han presentado actualizaciones de productos actuales, principalmente enfocadas a la estética.

      Efectivamente, la oferta más económica ahora mismo es la de Sprinter.

  77. Buenas tardes, entre el Polar Vantage m2 y Garmin 245, ¿Con cual te quedarías?. Los dos están más o menos al mismo precio. Lo usaría para correr, entrenamiento en gimnasio, rutas de senderismo y poco más.

    Greetings and thank you.

  78. Hola Eduardo. Tengo el FR245 desde hace una semana. Hoy salí a correr y a los 5 minutos me dice modo ahorro batería y empieza cuenta atrás de 30 segundos. Yo le doy a continuar xq tenía un 30 % de batería y sol iba a estar una hora. El caso es que cada 7-8 minutos volvía a salir el mensaje y al final, cuando acabé no ha grabado nada, ni recorrido, ni frecuencia, etc. Y aún le queda un 21% de batería. No entiendo esto. Tu sabes a qué se debe?

    1. El ahorro de energía sale cuando se está en la pantalla de búsqueda de sensores y no se ha iniciado la actividad. Tienes que volver a pulsar el botón para que comience el temporizador.

  79. Hola,siirven cualquier tipo y marca de auriculares inalambricos blutooth para el garmin forerunning 245 music,o tiene que ser algun tipo o marca en especial? Gracias

    1. En principio funcionará con el 99% de auriculares, sin ningún tipo de problema. Donde te puedes encontrar problemas es a la hora de que funcionen los botones como subir-bajar volumen, etc.
