The new Garmin Forerunner 25 comes to replace the Forerunner 15, which replaced the Forerunner 10. We've seen small improvements in each of the models, but the most important change comes with this new version, as in addition to providing a major jump in screen quality, it adds Bluetooth connectivity, which will allow you to synchronise activities as well as receive notifications from your mobile phone.

I always like to clarify where the devices being tested come from on this page. There are two options, either you buy them directly from the store so that you can offer the analysis as soon as possible, or the brand provides a test unit. In this case it has been Garmin that has kindly provided a unit, and once it is completed you will go back to where you came from; that is, Garmin does not give anything away in exchange for a positive or "not negative" opinion of any of its products. The tests are carried out completely independently, without any pressure from the manufacturer.

Remember that if you want to show your gratitude for the tests I perform and want to help support the site, you can buy the watch through the links I provideThat way I get a small commission for each watch, which is what allows this website to continue and covers some of the work I do.

Now that that's all clear, let's get on with the test. The good, the less good and the bad of the Garmin Forerunner 25.

Unpacking

The Forerunner 25 box is the classic Garmin box, made of cardboard with a plastic window through which we can see the watch. On the front icons you can confirm if the version you received is the one with only the watch or, as in the case of the test model, if it is the pack version with a pulse sensor

garmin-fr25-1

In this case, and since it's the pack version, the sensor is included, which I'll tell you about later. You'll also find the watch and the sync and charging cable, which will be relegated to a charging cable. Normally, you'll pair it directly with your phone via Bluetooth. Oh, there's also an instruction manual included that's so short, you can save on taking it out of its plastic bag. The best thing is to read this test, so you'll know how to use Forerunner 25.

garmin-fr25-2

This new Forerunner 25 is a major change from the model it replaces, Forerunner 15. And the first thing we can notice is the improvement in the quality of the screen, which has gone from a poor resolution of 55×32 pixels in the FR15 to a more than decent one of 128×128. It's a major change, not only on an aesthetic level (the truth is that the previous Forerunner 15 had a "shabby", even gloomy air), but also in terms of readability. In addition, the screen has gained in contrast, having a magnificent clarity in full daylight.

garmin-fr25-5

There are four buttons to control the whole device, being the main ones the ones on the right side. The red button (in this case, in other colors it will be the one that matches the model's color) is the one we will use to start and stop activities, as well as to confirm menu actions, while the lower one is the scrolling one. There is only one of them, so the scrolling will always be downwards, so if you miss the option you wanted to select you will have to go back to the beginning of the list and make sure you don't miss it in the second pass. When you are training that same button will allow you to pass between the different data screens.

garmin-fr25-3

On the other side of the clock we have the power button, which will also serve to illuminate the clock screen. Below this you will find the back button (to exit the menus) which will serve to manually mark laps as well as to show the different fields of the activity monitor.

garmin-fr25-4

The synchronization and charging pins are not protected against corrosion and are not necessary, as they do not wear out. The only thing you should bear in mind is that you should wash your watch after every use, as you do not want to let your sweat stay in that area.

Don't worry about getting your watch wet, as it's waterproof up to 50 metres, which will even allow you to swim with it (although it doesn't have a swimming profile so it doesn't offer specific metrics).

garmin-fr25-6

The design of the charging cable is changing. No longer is a hard-to-adjust clip used, now it's a base that attaches to both sides of the watch "hugging" it perfectly, allowing you to leave it safely charging in any position, even hanging from a plug.

garmin-fr25-7

The pulse sensor included in this model is the basic version, made of quite hard rubber. The truth is that it is not the most comfortable sensor available, and as I indicated in the test of the Edge 25should disappear to leave only the premium tape pulse sensor. Hopefully the arrival of the new sensors HRM-Tri make the premium model downgrade its category and be included in all models from the lower ranges, with the HRM-Tri being reserved for the top-of-the-range versions.

garmin-fr25-8

And once we've reviewed what's included in Forerunner 25, I should tell you a few things about the colours and sizes in which Forerunner 25 is available.

Colours and sizes

Unlike other watches, the Forerunner 25 is offered in two different sizes, giving a more compact option to ladies, who are usually forced to wear fairly masculine watches. Not only will they differ in the size of the watch, but also in the colors in which it is offered. These are the colors that are offered.

  • Size smallPink/white and purple/black
  • Large size: Red/black and black/blue

Garmin Forerunner 25 - Colors and Sizes

Therefore, the dimensions and weights vary depending on the model in question. While the largest model has a 40x40mm case, the female model is reduced to 36x36mm, much more suitable for a narrower wrist. In both cases the depth is the same, 13.9mm. This reduction in size implies a narrower strap in the model for them, and with the reduction of material used also comes a lighter weight, from 39 grams to only 31. Garmin Vivoactive like the lightest GPS watch.

The toll that has to be passed through the smaller size is to have a slightly smaller screen, going from 23x23mm to 18.5×18.5mm. However, the resolution remains identical at 128×128 pixels. This is a frankly remarkable step from the Forerunner 15 that it replaces, as it now offers a screen with very good contrast and resolution.

Running with FR25

The Garmin Forerunner 25 was created with one main purpose, to run, and all the options it offers are based on that purpose. However, you should be aware that it is a simple clock, both in terms of the features offered (more than enough for the type of user it is focused on) and when it comes to configuration. This means that there are no long menus to activate or deactivate options, nor complex functions that you won't understand if you are not a very advanced user.

When it comes to displaying data on screen, it is possible to set up two different screens, and you can select two different data on each screen. They look quite generous in size, so a quick glance at your wrist will allow you to see the most important information.

Garmin Forerunner 25 - Data Screens

These are the different variables you can select:

Weather

Distance

Rhythm

Calories

Return time

Return distance

Rhythm of return

Average pace

In addition to these variables you add on the data screen, when you connect a heart rate sensor a third screen is added showing the current heart rate and the zone you are working in.

Garmin Forerunner 25 - FC Zone

And there's a fourth screen available, where you can see the time and the remaining battery level.

Other options you can configure are the way to mark laps and the autopause. The first one will allow you to activate or deactivate the automatic lap marking function, as well as the distance it will mark (default 1 kilometer). You can also activate or deactivate the lap button. In case you activate it, when you press the back button (the lower left one) you will create a lap, regardless of the distance.

Garmin Forerunner 25 - Turn Options

You can define settings up to two to three bikes in your training computer.

Garmin Forerunner 25 - Marked laps

As for the automatic pause function, you can activate it so that the recording stops automatically when you stop (when you are at a traffic light, when you talk to your neighbour, etc.).

Finally, the clock allows you to choose various running modes. You access this menu from the start screen. If you scroll down before pressing the start button, you will find the following:

Garmin Forerunner 25 - Career Options

The basic mode is the mode you will normally use. The other modes allow you to select different targets, and each one will add a screen with data of what you have set as a goal. The available modes are as follows:

  • Basic
  • Career/walking
  • Virtual Pacer
  • Weather
  • Distance
  • Calories

In running/walking mode you can set a time for walking and a time for running. This is especially useful for those of you who are just starting out and cannot yet keep up with running for a long time.

Virtual Pacer allows you to enter a target pace and see on screen whether you are ahead or behind your virtual opponent. The time, distance and calorie modes do not need much explanation. You select the final goal and FR25 will discount as you complete your workout.

The last option you can edit is to set a heart rate alarm. Forerunner 25 allows you to select between zone 1 and zone 5 (which is automatically set in Garmin Connect or which you can edit with your choice of keystrokes).

Garmin Forerunner 25 - Zone Alarm Selection

Or you can set the heart rate zone manually, either from the top or the bottom. When you do so, the watch will beep whether you go over the marked range or are too relaxed. Both are independent, so you can set only the top range, the bottom range or both.

Garmin Forerunner 25 - Zone Alarm Selection

Starting to run is as simple as pressing the activity button and waiting for the watch to receive a satellite signal and, if you have the sensor, to connect to it. The display will indicate that you should wait while it searches for satellites. It is on this screen that you can access the race option settings.

Garmin Forerunner 25 - Satellite Search

Once you have completed the search bar, you will quickly move to this other screen, where you can start the activity.

Garmin Forerunner 25 - Ready to go

Forerunner 25 supports satellite caching, which speeds up the initial reception time. This cache is downloaded with every sync you make with the watch (via cable or Bluetooth), so if you have the watch paired with your phone it will always be up to date. And since the best way to know how long it takes to receive a satellite signal is to see it for yourself, here's this video to check it out. The search is done 50 kilometres from the point where I finished the last activity, which was two days earlier. So the satellite location was not memorised.

The instantaneous beat is displayed in multiples of 0:05, as is now the custom with all Garmin watches. This means that, by displaying instantaneous beat, you will go from 4:40 to 4:45. However, if the metric you have selected is the average beat or lap beat, that will go to the second.

The rhythm shown is very stable, firstly because the data recording is not done every second as in the higher range clocks, and secondly because the rhythm is filtered, so that it is not exposed to the classic ups and downs produced by the existing error when receiving the correct positioning (the typical error, with full signal, is 1-3 meters). So that you can see the difference, this graph will show it clearly.

Garmin Forerunner 25 - Speed Comparison

The purple line is the rhythm measured by the Garmin Fenix 3The blue line is the file obtained with the Forerunner 25. Both final average pace and distance have been the same in both cases.

Garmin FR25 - Activity comparison

So where's the difference? Well, the way the instantaneous pace is displayed on screen. Forerunner 25 is much more stable, and if you're working out at 4:45min/km continuously, that's what you'll see on screen for the whole workout (if you keep up the pace). Why does the Fenix 3 vary so much on the graph? Well, because the pace is not filtered and it's much more responsive to changes in speed, so when you're doing a workout with changes in pace (such as sets), the Fenix 3 updates the pace on screen before the FR25.

Normally I always criticize Garmin for continuing to use intelligent data recording, but in this case and with this model, I must agree with them. Their target audience probably does not perform series training and rhythm changes several times a week, so a more stable rhythm will generate much less doubt about the operation of the watch. Garmin's intention is to have a model that is simple and clear to use, and this is the best way to achieve this.

However, at no time is the pace shown wrong. In fact, in a training session conducted in conjunction with the Suunto Ambit3For some strange reason, the Ambit3 was determined to set a faster pace than the real one, even though the lap time was automatically set to the same kilometer.

And again, this way of taking data doesn't mean that the distances don't match reality. In fact, in all the training I've done combining it with other devices, the resulting distance has always been very similar.

On the street, Forerunner 25 won't be the only place you'll be able to run. You can also use it indoors, running on a treadmill. Thanks to its internal accelerometer, you'll have distance and pace data, not as accurate as when you're running with GPS enabled, but pretty accurate. This measurement is done thanks to the clock's internal accelerometer, which is the same one used to get the data used by the activity monitor; and also for outdoor running cadence measurement, something the Garmin Forerunner 25 is also capable of recording.

You cannot select this cadence data for your data screens, but it will be recorded in the FIT file of the activity and you will be able to consult it in Connect after synchronizing the clock with your phone or computer.

Using Forerunner 25 in other activities

Even though the Garmin Forerunner 25 is a watch designed for runners, it doesn't mean you can't use it for any other activity that involves physical movement (even your nights out). But you should keep in mind that after synchronizing your activity, you'll have to change the sport you're doing to keep track of your overall workout.

You can also use it while riding, since in the options you can choose between showing the pace (min/km or min/mile) or changing it to speed (km/h or mi/h).

Garmin Forerunner 25 - Pace or speed selection

After completing the activity, you must remember to enter the history section and delete the new records, as you will most likely have broken all your race records. Later, in its specific section, I will talk more about them.

It is also possible to use the watch for any other activity, both with GPS on and off, such as weight training sessions at the gym or spinning classes. You will not have extensive data on the activity, but if you do it with the pulse sensor you can have data on calories consumed, as well as the corresponding pulse graph. For example, this running technique session

Garmin Forerunner 25 - Race Technology

Activity monitor

The activity monitor reached the lower end of the Garmin range with Forerunner 15. As you might expect, it's also found in Forerunner 25.

So with the FR25 you can not only record all your workouts, but also track your daily activity and your night's rest. During the day it will estimate the steps taken (remember, this is not a real measurement, but a mere approximation), which will translate into distance travelled and calories consumed. And in case you sleep with the watch on your wrist, you will also have the analysis of your rest the next morning.

You can find the basic data of the activity monitor in the main screen of the clock. By default the date will be shown below the time, but we can change this value by pressing the back button.

When some time passes and you haven't moved, an inactivity warning bar will appear below the Activity Monitor settings, receiving a warning once it is complete to notify you that you have not moved for a long time, and recommend that you activate. To remove this warning you will have to walk for a while, about 100 meters.

Garmin Forerunner 25 - Inactivity

Normally, instead of the notification bar, you'll see a rectangle that will be filled in as the day goes by, if you walk. Your goal is to fill the bar completely, in which case you'll be notified. So what's the goal? Well, by default it's set to a dynamic goal, so it will adjust to your activity every day, so it's realistic and achievable. But you can also set a goal manually through Garmin Connect.

The daily activity data can be consulted directly on the clock screen, accessing the history menu.

Garmin Forerunner 25 - History Menu

Where you can choose a day and see the steps taken and their comparison with the objective set, as well as the estimate of distance and calories consumed.

Garmin FR25 - One-day activity

Although the most convenient way to check the data is on the web or in the mobile application, after the corresponding data synchronization, if your phone is paired with your clock, this synchronization will be done automatically throughout the day.

As this activity data is uploaded, you will be able to access the Garmin Connect website to view activity not only from past days, but also from the current day. You also have the ability to synchronize your Garmin Connect and MyFitnessPal accounts, sending activity data from Connect to MyFitnessPal, and receiving calorie data from MyFitnessPal.

Garmin Forerunner 25 - Steps of the Day

Within these steps are also those that you go through during your training, because they also add up to reach your goal.

Garmin Forerunner 25 - Activity on a Training Day

In Garmin Connect, you can access comprehensive activity reports to see what your daily, weekly, or monthly trend is. These graphs show the targets you have achieved and the months in which the target has not been met (in my case, June).

Garmin Forerunner 25 - Monthly Target

The Activity Monitor not only records your daytime activity, but also your nighttime activity by monitoring the quality of your sleep and identifying the phases of your sleep. There are three different phases: deep, light and awake sleep. Each phase is determined by the movements you make during the night. Garmin has been recording this data automatically for some time now and there is no need to activate any specific mode before going to sleep, as the identification will be done at the server level, after synchronising the data.

As with activity data, sleep data will be synchronized with Garmin Connect and you can review it later on the web and in the mobile application.

Garmin Forerunner 25 - Sleep Analysis

If you see that there may be some miscalculated data, you can always modify the schedules manually. Usually the detection is accurate, but sometimes it can happen that if you are reading in bed and you move little, identify that you have already gone to sleep, when you still had enough to do (the end of that novel, which became interesting ...).

As for the step calculation itself, you must keep in mind that it is an estimate, and as such it does not have to be exact. It is not, but it is quite close to reality. In fact, using several activity monitors simultaneously, the steps recorded are very similar.

Garmin Forerunner 25 - Step Measurement

garmin-fr25-step-2

Garmin Forerunner 25 - Step Measurement

There are days when the calculation performed by both devices are closer than others, but they are always in the same range of steps and distances.

Notifications and connectivity

One aspect that the new Forerunner 25 has seen improved is that of mobile notifications. New to the range (FR15 did not have them), it comes much better than its cousin the Edge 25If only call and SMS notifications are accessible on the cycling unit, Forerunner 25's notifications are complete. What's more, when you turn on Bluetooth, a new menu option appears, allowing you to access all the notifications on your phone.

Garmin Forerunner 25 - Notifications

Not only will you receive the notifications on screen when you arrive at your phone, where they will be displayed briefly, but you will also be able to access them at any time from the comfort of your wrist, since within that option you will have them all.

Garmin Forerunner 25 - notification

These notifications are received because it is the Garmin Connect application that acts as a bridge between the clock and your phone's notification system (for iOS and Android). By default there are a series of notifications enabled for the most common applications (classic mail, WhatsApp, etc), but from the application you can add others that you have installed, such as Inbox or any other application that sends you notifications of any kind (sports scores, messaging, etc).

Garmin Connect - Notification Selection

Within the clock menu you can access the notifications menu, where you will find all the notifications that you have not yet read or discarded.

Garmin Forerunner 25 - Notification List

If you want to read any of them, simply select it and press the main button to access it.

Garmin Forerunner 25 - Notification deployed

In addition to notifications, the Bluetooth connection will also be used for automatic synchronization of activities, either because you have your phone with you while you train or because it connects to your phone as soon as you return to where you left off. This makes synchronizing activities a real piece of cake, since it doesn't involve any effort on your part. No searching for the sync cable, turning on the computer or pressing any buttons on the watch or phone. It simply connects and synchronizes whatever is pending. Magic!

Finally, Forerunner 25 also offers LiveTrack functionality. Operation is similar to the rest of the Garmin range (both watches and cycling units), where the phone sends GPS data as ANT+ sensors from the watch to the Garmin website, so the phone's battery is barely affected (since it's not with the GPS connected) and simply sends data regularly to the cloud platform.

Anyone you provide the tracking link to will be able to see your activity, check how your career or training is going and see that you are indeed still alive.

Final Livetrack

Pairing is done through the Garmin Connect application (not through the phone's Bluetooth options) and needs the application installed to work. But once you've made the first pairing you can forget about it altogether - pairing is constant and automatic (also for activity data).

Clock and lighting

As a clock it is a very simple device. It shows the time of day (which can be set to 12 or 24 hours) and the date. What it does allow us is to set the time automatically at each GPS connection.

Garmin Forerunner 25 - Watch

The only additional option offered in this mode is to be able to set an alarm, which will be simple and without any kind of repetition (i.e. you cannot create an alarm to wake you up every day at 7:00).

Garmin Forerunner 25 - Alarm

Other Garmin models offer various options, not only for automatic or manual illumination, but also for specifying how long the display remains on.

Garmin Forerunner 25 - Illuminated display

It does not allow you to leave the light on indefinitely, something of great importance for those of us who train at night, forcing you to press the light button every time we want to see some data from our training.

Battery life

I was quite surprised by the battery test (pleasantly). Garmin announces an active battery life of up to 10 hours using the GPS (up to 10 weeks in clock mode).

To check this, there's nothing easier than doing an activity of at least that length. So with the watch fully charged, I started an activity, leaving it on the roof, waiting for the battery to run out. Then I went to sleep. One of the most stressful tests I put watches through...

In the morning, when I had to leave, it had been active for over 9 hours and was already giving low battery warnings. Instead of leaving it in the same place, I chose to take it with me, and put it in the car.

After arriving at the destination, I was still recording the activity, so I had to leave it there too. And I was already spending the 10 hours of activity extensively. The final result is what you see in the image, almost 12 hours recording activity continuously.

Garmin Forerunner 25 - Standalone

Given the size and weight of the watch, which is quite small, it has a fantastic performance, more than enough to finish any event, even a marathon, regardless of your level.

Personal records

Forerunner 25 also features the personal records feature we've seen on other models. The watch will keep the best records you get from your races or workouts, but they're the ones you get with the watch, because by default it doesn't synchronise the records you've previously stored in Garmin Connect. To do that, you'd have to log in to Connect and send the records data to the device. Otherwise, you'll improve the records bit by bit.

So in the first few races you'll be getting data far away from your real marks, like in my case with the first training with the Forerunner 25. I'm slow, but I'm capable of going down from 5:20 in a kilometre. If I try hard, I'm sure I'll be able to get it down to 5:19.

Garmin Forerunner 25 - Records

The records stored are for the following times and distances:

  • Best time for 1 km
  • Best time for 1 mile
  • Best time for 5 km
  • Best time for 10 km
  • Best time for half marathon
  • Best time for marathon
  • Longer distance traveled

Remember that the watch only has a running profile, so if you do a cycling activity, for example, you should be careful with the records you store, but you can always delete the record or tell the watch that you want to keep the previous record.

Garmin Forerunner 25 - Break Record

It's the only way not to break world records on every bike ride.

Garmin Connect on the web

Garmin Connect is the website where you will find all the information you synchronize from your watch, both training and your day-to-day (and night-to-night) activity. There are also a number of other features, such as activity reports, the mileage log in your shoes, etc. All these functions are free and included with the purchase of the device.

This is the main page you can find when you log in to Connect. You can organize it as you like, adding or removing windows as you wish. At the top right you can find a "+" button, which will allow you to create more desks, for example one for your workouts and another for your daily activity.

Garmin Connect

The section that you will consult most will be that of your activities. Here you will find absolutely all the information about your race. At the top you will find a map with the route taken along with the basic details of the workout, such as distance, time, average pace or calories.

Below you have the graphs of the different variables. You can enlarge each of them to see it bigger, as well as compare several values with each other.

At the bottom you can see the extended details of the workout, with more specific data than you find at the top.

Garmin ConnectIf you click on the interval tab, you can find the partial detail of each lap. If you mark the laps automatically it will be for each kilometer covered (or the distance you have selected), although you can also deactivate the automatic laps and mark them manually; perfect if you have structured workouts such as 7km smooth, 4km at running pace and 5km smooth. That way you can see the specific data of each section of that workout.

Garmin Connect

And if you're still short of information, it's also possible to automatically synchronize your Connect account with other platforms, such as Strava or Endomondo, so you have plenty of options to choose from.

Garmin Connect on your mobile

In the Connect mobile application, available for Android and iOS devices, you will find the same information as on the website, organized in a different way but essentially the same. And that information will be both from the training carried out and specific data on activity, sleep, use of equipment, etc.

In addition, this application has seen an important update, renewing all its aesthetics last week. I leave you a gallery of images so you can see what kind of information you will find and how it is represented in this new application.

Installing this application on your phone is also essential, since in addition to serving to synchronize your phone automatically with Garmin Connect, it is also the mandatory gateway for notifications from the phone to reach your watch. It is the common link between the two, and it is also here that you can specify which notifications you want to receive and from which applications, adding any applications that are not listed by default or removing any of those included immediately after installation.

My opinion

I'll be honest with you, I love to try this kind of device from time to time. Simple, easy to use, and they do everything you ask of them - and not a thing more. Forerunner 25's ease of use is commendable. There are no complicated menus, no options buried within other options, and you don't need to wander through undescriptive menus until you find the option you're looking for.

Simplicity is precisely one of the selling points of this model. It is aimed at those who do not want to complicate their lives with 10 pages of data, data and more data. And although the potential customer it is aimed at is the casual or beginner runner, it is not exclusively limited to them. In fact, during my training sessions I have already seen more than one runner with an FR25 on their wrist, and they were certainly not beginners and did not have the pace to be one.

Garmin FR25

The qualitative leap from the previous model is important. Aesthetically it has improved, especially thanks to a higher quality screen. In terms of software it's quite similar, but now it allows you to select the values you want to have on each data page, instead of being restricted to what Garmin thinks is right for everyone.

The most important new feature is Bluetooth connectivity, allowing you to synchronize your watch very conveniently without having to constantly connect it each time you perform an activity, and notifications work very well.

I really can't say anything bad about the FR25, apart from not allowing the light to be left on permanently. The only thing it can pale in comparison with other competitive models that offer more features for the same price, like the Polar M400Although they are in the same price range, they are two very different products, and for someone looking for something basic and simple, the Polar can become too complicated.

In short, is the Garmin FR25 the right model for you? If you are looking for a simple watch, regardless of your level, the answer is a very big YES. If you don't need any more features, don't pay for them.

And here's the proof. Thanks for reading it! Since you've managed to read this far, continue on down a little further as you'll find two great ways to help the page.

 

Did you like the test?

  1. Hey, first of all, congratulations on the blog.
    A very quick question, you say that the heart rate band is not the most comfortable, I see on the Garmin page that the device is compatible with the premium band. Do you think it is worth buying the premium band on one side and the watch (without basic band) or is it not so bad?
    Thank you very much.

    1. It depends on the price. With the difference that there is today on Amazon, 15 Euros, I would opt for the version with a pulse sensor. It is logical.

      It also depends on the person, their constitution and the use they are going to make of it. For sessions of 1 hour or less you are not going to have problems, but it would not be the sensor I would use for long 3 hour shoots. And of course, it is compatible with any ANT+ sensor (not only Garmin's), both chest and tissue tape as well as optical wrist sensor.

  2. Hi Eduardo, congratulations on the blog and thanks for this fantastic review, you have my vote.
    One question: I'm a beginner runner and I want to buy my first watch. Without going into prices, is this Garmin or the Tom Tom Runner 2 Cardio better for someone in my profile?
    Thank you very much and greetings,
    Carlos

    1. Hi Carlos

      Thank you for your good words and your vote!

      Without having tested the new Runner 2 (I'm still after TomTom to get a unit) I can't recommend it or rule it out, especially because although in terms of software it's very similar to the TomTom Runner, the reliability of the pulse sensor is very important, and I haven't had the chance to analyze it yet.

      What I can confirm is that, as a beginner's watch, this Garmin is a perfect fit for you. Check out the Forerunner 220 too, as the price of the 230 has dropped (although you lose the activity monitor and mobile notifications).

      1. Thanks a lot for your answer. I'll keep thinking about it until I do the King's letter, but so far everything points to this Garmin Forerunner 25.
        Greetings,
        Carlos

  3. Very good review.
    I only miss some sections about connectivity (Bluetooth Smart vs ANT+)
    For example: there are already ANT+ mobile phones out there and beginners are wondering if Bluetooth connectivity in the garmin is really useful if you already have ANT+ connectivity in the mobile to receive the signal directly from the chest band.
    Greetings

    1. Jose, you're confusing the terms. Bluetooth is used ONLY for data transmission (synchronization and notifications), while ANT+ is for connecting to the sensor. They're two different things.

  4. Hello,
    Between the forerunner 25 and the polar m400, which one would you take?
    I practice paddle surfing, swimming and sporadically I ride a bike or go for a run.

    Greetings and congratulations on your website.

    1. In your case I recommend the Vivoactive. At present no watch supports paddle surfing as a sport, although the Fenix 3 just received it in beta version. It is possible that the Vivoactive could also receive it, as it would be much more logical.

      It has support for swimming metrics, and you can use it for cycling and running. You can see the proof here: https://www.correrunamaraton.com/garmin-vivoactive/Plus it's now on sale.

  5. Very good analysis. This christmas I'm thinking about buying a GPS watch and I'm between this Garmin Forerunner 25 or the Polar M400. I train 4 days a week in almost every area of the countryside and now I'm hooked on the trail. Which one would you recommend? I'm also considering the Garmin FR 220 but I'd like your opinion. Best regards and thanks for these articles

    1. It depends on the degree of configuration you need. If you prefer a simple to use watch the 25 is the option. If you prefer more configuration and customization then the 220.

  6. Hello!
    Congratulations for this blog, I think you are doing a great job. I just bought this Garmin model and it has served me much more this post than the manual itself, thanks a lot!
    I have a question about whether you can help me, I can't use it as a normal clock, the display is continuously off, I have to press one of the buttons to turn it on and the display flashes and then it goes off. I thought it was some sort of battery saving option but I don't see that setting anywhere
    And from the Garmin connect app I can't configure which notifications arrive at my watch and which ones don't so they all arrive by default...
    Thank you very much for everything, I share in my networks!

    1. There is no setting for the screen illumination, you cannot select the time it should stay on.

      As for the application, you can choose the applications that will send notifications in settings - smart notifications. From there you can add or remove the ones you want.

    2. Hi! The other day I bought this watch and I had the same problem as you (screen off, display blinking, etc...) I took it to the store and they told me that that was not normal, since the screen should always be on as if it was a normal watch. They asked me for another one to change it.
      Rutilita, what happened to yours in the end? Did you solve the problem?
      Eduardo, in all the time you've used it, have you ever lost it?
      Thank you!

      1. Hi! what I did was update the software via GarminExpress and so far it has worked perfectly. also I had heard that the app for iphone was not linked since the last update and I link to the first one and so far everything works perfectly. I am delighted with this watch!

  7. Hola, lo primero felicitarte por este magnifico blog y el excelente trabajo que aportas para facilitarnos a todos la decisión de compra de estos juguetes!!!. Mi pregunta como principiante para volver a comenzar a correr después de una larga, largisima temporada parado y actualizar mi ya antiguo Polar…. es si ¿puedo utilizar este forerunner 25 sin tener que llevar la banda de pecho y prescindir de ese dato?, siendo de momento suficiente e importante para mí, el tiempo y la distancia.

    1. Thank you, Pedro.

      Of course, if you don't need to have heart rate data you don't have to use the pulse sensor. All other functions are exactly the same.

  8. Thank you very much Eduardo for the clarity in the explanation of the product.
    Although I have a doubt: if I run on a treadmill it also calculates the training distance and other data ... Because if it is equipped with an accelerometer ...
    Thank you.

  9. Hi Eduardo, congratulations for the website and the reviews, I practice fitness and about 5 times a week I go out to run exchanging training days between fartleks and continuous running, I'm not a great long distance runner but on continuous running days I do about 6, 7 km. My doubt is that I'm between this or the cheaper forerunner 10, the glue that brings less functions and without a pulse meter... the 220 goes away, or another option you recommend. A greeting and congratulations!

  10. Hi, I really liked your blog, I just wanted to ask to confirm, although I thought I read that it was compatible. I had a Garmin forerunner 110 and was thinking of buying the 25th, my question was if the chest strap would work for this one, since I didn't use it much and it's in good condition.

  11. Great analysis again.
    I think it's my watch.
    I'm only assailed by one doubt with the daily activity.
    I'm a night worker and I sleep during the day.
    Do you know if it measures daytime sleepiness?
    It's important to me.
    Thank you very much.

    1. You can set your sleeping hours through Garmin Connect, so you should be able to do the detection correctly within the range you are given. Other than that I can't tell you more, as it's something I haven't been able to try in person.

  12. I already have my garmin forerumner 25 and besides running I do spinig... You could tell me how I can use it to see my performance in this acivity. And you could tell me xq I can't read my wasp when I read other notices.
    Thank you very much.

    1. For spinning, if the bike does not have sensors, you can only follow the heart rate.

      As for whatsapp, check in the phone's application that the notifications for that program are activated.

  13. Thank you as always for responding quickly.
    Yo creo que el garmin Forerunner 25 es mi reloj.
    Just a couple of questions, see if you can help me out.
    I looked up the garmin connect application and read very bad reviews about what gives a lot of problems when synchronizing
    Is this so?
    También quisiera saber si cuando activas el gps para andar o correr y tienes el reloj en modo actividad diaria lo que andes o corras te lo mete en el cómputo global tu actividad de ese día.
    I don't know if I'm making myself clear.
    Thank you very much.

    1. There is no problem with Garmin Connect synchronization. It is regular and error-free. Any activity you perform will appear in the global count.
      On the one hand, what you walk without specifying an activity as such, and on the other hand, races or walks with the use of GPS on the other.

  14. Hello!
    Finally, I decided on the GF25 in size S. I'm happy with it but it turns out that although I have it selected in miles both on the clock and on the smartphone, in the end it reads in miles. And it's really frustrating. Has this happened to anyone? Is there any way to correct it?
    Thank you.

  15. Thank you very much for the review! I think your work is spectacular.
    I have a rookie question, can the fitbit charge hr bracelet be linked to the Garmin 25 as a heart rate monitor, i.e. use the fitbit as if it were a MioLink?
    Thank you very much!

  16. Hello.

    I just read the review you wrote, and first of all, thank you.
    See if you can help me because I think this watch does what I want it to do.

    My favorite sport is walking dogs, especially, making mountain routes with them, sometimes we are 2h and sometimes we have lost a little and we have been 8h.
    My new phone, I'm having a bit of trouble recording tracks with android apps, so I want a GPS clock to keep track and save routes so I can repeat them at some point.
    If I synchronize my watch with my cell phone, can I see in real time where I am?
    And would you recommend another watch for these activities?

    Thank you very much in advance.
    Greetings

    1. Se me olvidó comentar, que uno de los motivos por el que me he fijado en este reloj es por su tamaño. Tengo la muñeca bastante pequeña y por ejemplo el Polar M400 me queda “aparatoso”. El TomTom Runner 2 un poco mejor. (Son los dos relojes a los que había echado el ojo primero)

    2. You could use the LiveTrack option for both yourself and anyone you share the link with. Tracking.

      For that simple use, you have more than enough with the FR25. And as you say, it's quite discreet in size.

        1. By opening the activity in Garmin Connect, you can select the type of file to download in the upper right.

  17. Sorry, I'm a beginner and the only sports I practice are spinning, cycling, running in the colony, football and frontenis, which would you recommend between the FR25 or the M400? what I'm looking for most is just measuring the heart rate

    1. If you want simplicity Forerunner 25 is easier, but it doesn't have another sport profile, in your case I think it's worth spending a little more time with the initial setup but have everything better configured according to the activity.

  18. The analysis is a luxury. Congratulations on the success of your website and thank you for sharing your opinion and experience with us.
    I would like to ask if it could be used as a basic computer (km travelled and speed) on bike routes. I think this FR 25 is a great product but having the m400 for 147 euros in the links of your blog I doubt it very much (although for features the polar is big).
    Thanks for all the work, Eduardo!

    1. Yes, you could do that perfectly, set speed instead of pace and after synchronizing the activity with Connect change the activity manually.

      The M400 has the advantage of being able to set up several different sport profiles, but it is true that although it is not a complicated one to use, it does move away from the simple watch profile that the FR25 has.

  19. I have it for a couple of days and everything is fine, however I detect that it takes a lot of time to get my gps. I have updated it to the latest version and it takes me minutes (if I am inside the house up to 5 minutes and sometimes it doesn't even take it), do you know why?

    When I go for a run, I have to wait a couple of minutes at least on a bench until I fuck him, and I don't understand why.

    1. To get a GPS signal you need to have good visibility to the sky, something that obviously does not happen inside a building.

  20. Excellent analysis! Thank you very much, I just bought it and I certainly found out more in your review than in the manual!

  21. Hello good afternoon, first of all CONGRATULATIONS for the way you work all this!
    Secondly, the more I read, the more I doubt (positively).
    I'm between TomTom Runner, the Garmin FR 25 and I love the Garmin FR 220 but it's a bit pricey. I'm almost more convinced by the FR25 but that's why I'm asking for your opinion.
    I don't mind wearing the chest strap, which pretty much rules out the optical sensor. Interval training and the GPS signal are important, as is a good app for viewing data and so on.
    I would ask you to please recommend one.
    Thank you very much.

    1. Both the TomTom and FR25 have good GPS performance, but if the workout review application is important then there is no doubt, the Garmin is a much better choice.

  22. Hi, a few weeks ago I bought myself at garmin 25 in new york and I came back to argentina and tried to use it and the GPS didn't detect my satellite... it's hung up loading, I don't know how I can do to restart the satellite or this is normal... thank you very much

    1. If you are outdoors and have a view of the sky, you should receive a satellite signal in no more than 5 minutes.

    1. Simplicity: Garmin Features: Polar

      It already depends on what you prefer, whether more options or quick and easy handling

        1. i'm going to start in the world of gps watches so everything that comes will be good...although i'm not starting in the world of running since i do 90 km a week more or less at 4:00, 4:30

          1. So I guess you're planning on doing some training series and stuff.
            Better the Polar that, although more basic than other more expensive watches, allows more things.

          2. Of course I want it for series, for fartlek and change of pace...
            Thank you very much for your opinion!

  23. Hello and congratulations on the blog.
    One question, how many kilometers can you measure in a single session? More than 100 km?.
    Thank you and greetings

  24. Just one question, on the same customizable screen you can see at the same time, heart rate and time.

    1. This is not possible, because the heart rate has its own specific display and cannot be selected as a data field.

  25. Hello
    acabo de recibir el reloj y me parece muy completo para lo que yo necesito. tengo una duda: si lo utilizo con el uso interior, ¿ es posible usar el pulsómetro? es decir, para actividades de cardio que realizo en el gimnasio he pensado que es es la mejor opción, la de uso en interior.

  26. Excelente análisis tengo una duda entre estos dos relojes Forerunner 25 o el vívoactive salgo a trotar y hago bici ocasionalmente en tema de precios el F-25 cuesta 105 $us. nuevo y el vivoactive está en 99 $us. (Refurbished), reacondicionado cual me recomiendas ya que el precio es bastante parecido y una duda más conviene comprar reacondicionado ambos relojes están en Amazon, y muchas gracias.

    1. I'd stick with the Vivoactive, I think it's a better watch, especially for a screen that shows more information

  27. Eduardo good morning, I consult you yesterday I buy this device so far I have tried it in basic issues. But it strikes me that I constantly get a notification "Heart Rate Too Low", being that I'm on the street walking and the pulses are between 80 and 110. I wanted to know if I will have to configure something from the web or app. I hope you can help me.

    Greetings.

  28. Hi! Thanks for the info. I'm making a query, in the step counter I just started the diab that I did 436 steps and spent 1533 lime. Something is wrong, Xq is impossible that with so few steps spend so much lime. What is wrong???? Thanks!!!!

    1. The calories it shows are the basal ones, they include the consumption of calories we need just by being alive.

  29. Very good analysis, thanks. Just a detail, I've been with it for a few days and it can be used as an alarm clock(the clock must be on). Be careful not to have the alarm off in Garmin Connect, when synchronizing it it turns off the clock.

  30. Hi, I bought a Garmin Refurbisher, I don't know if that's the reason why the backlight doesn't turn on, or if I need to do something specific to activate it?

  31. Hi, Eduardo,

    Thanks for your analysis, very complete and useful. The Forerunner is a model, as you say, for beginners and I want to add for "finishers" too. That is, those of us who, because of our age, run 2 mn/km slower than when we were good, but we were forty years old. And that we don't do series anymore, nor changes of pace, we settle for our 10-12 km, but very close to 5 mn/km. Consequently we want a simple GPS, and with big numbers to be able to see them training.

    But let's get to the point, in your analysis you don't comment on the memory of the clock, that is, how many activities it can save, before it starts deleting the last one to record a new one. It's just that I read, I don't remember where, that the memory was small, and that it didn't save more than 25 activities simultaneously.

    Do you have information about this feature of Forerunner 25?

    Greetings and thanks again for your work.

    1. The truth is that I can't tell you, because I've always had all the clocks synchronized with my phone, so as soon as I finished a session they were already synchronized. If you sync frequently, everything will be uploaded on the Garmin website and when you overwrite workouts they will be synchronized.
