Is this the watch to rule them all? Sort of like Frodo Baggins ring, but in GPS watch format. Well, it could be for some, because since Garmin introduced the first Fenix in mid-2012, the range has undergone a huge transformation. It is no longer "just" a watch for the more adventurous public. The Fenix 2 is a watch that serves for more than just going out on the mountain. It serves for more than just going out for a run. It serves for more than just helping you train.multi

I recommend that you don't miss a single line of what you can find below. Make yourself comfortable, grab a beer and in about 10 or 15 minutes you'll know if this GPS watch is right for you.

I hope that this test will be very useful and help you with the purchase of your new training equipment. It is clear that you will live with it for many hours, and for many years, so you will want to be totally sure of your purchase. Remember that if you find it useful and you are going to buy it, you can do it through the Amazon links you'll find at the end of the analysis. That way you'll help me run more tests like this in the future.


The Garmin Fenix 2 is presented in an elongated box, quite different from what we have typically seen in Garmin presentations (it was usual to see boxes with a blue colour and a more square format, to my taste quite ugly). Now it looks like a box from a bottle of wine. But a good wine. In this case, this Fenix 2 comes in a kit together with the HRM-Run pulse sensor, quite more advanced than the classic pulse sensor I will talk about later. And in my opinion, this sensor is essential with the Fenix 2.

Garmin Fenix 2

To access the watch, we have to do it from the bottom. And that's when you realize that the box looks like a Matroska doll, since everything comes quite compartmentalized.

The box, once opened, is dismantled into two pieces

All you see in the picture is what's in the box. Once deployed, it's impressive. In addition to the watch, you'll find the Garmin Premium Soft Strap, a fabric strap much longer than the plastic one, a mains charger, a sync and charging cable, tools to replace the strap and, of course, the HRM-Run sensor.

It's a good thing that Garmin included the fabric strap with the Fenix 2, as it allows you to wear the watch on top of heavier jackets, such as ski or mountain jackets.

Garmin Fenix 2

But let's go to the watch, which is the most important thing. It is quite big and military looking. The case is not made of metal, but of polymer. This obviously helps with the weight of the set, because despite being visually large (well, and really), it is something that is not reflected in the total weight of the set, which goes to 85 grams. The glass is mineral, which without being sapphire as in some Suunto models, is above other solutions made of plastic much less resistant.

The screen has a resolution of 70×70 pixels, inverted, that is, the background is black and the text is white, depending on which people this may be a problem, since it is not modifiable.

Garmin Fenix 2

But if you prefer a traditional screen, Garmin has thought of you too. You have the Garmin Fenix 2 Special Edition where the display is normal (black text on a white background) and the watch strap is red.

The diameter of the box is 49mm and the thickness is 17mm. Clearly it is not designed for narrow wrists, although for those of us with large wrists there is no problem, some even consider it to "fit".

Garmin Fenix 2

The watch has a socket where the connector for charging and synchronization fits. This makes it very easy to connect the watch and does not stop charging in a hurry. It also allows you to charge it while you are using it, for example in the mountains, as long as you have a charging battery (the ones used for mobile phones, for example).

On the back you can find the data and charge connections. In spite of having the connections "in the air", the watch is water resistant, up to a maximum of 50 meters. That is, it is designed for open water swimming and light diving, but don't go to the abyss to look for monsters. Or, at least, leave the Fenix 2 on the coast and then you can go wherever you want.

Garmin Fenix 2

Here's the clip itself. There's not much mystery about it, a clip that fits the shape of the watch. By the way, when the Fenix 2 is created via USB, you can extract all the data manually without the need for management software. And you can also update the Fenix 2 to the latest version without needing the software installed.

Garmin Fenix 2

And finally, here's a little wonder: Garmin's sensor with the Premium Soft Strap. Same old thing, right? No, because now they've painted it a white muppet. What for? Well, to differentiate the normal sensor from the new HRM-Run, which is compatible with the new high-end Garmin watches (besides the Fenix 2, right now other watches that can benefit from its advanced options are the Forerunner 620 and 920xt).

As always in Garmin is an ANT+ sensor, so it is still compatible with other devices that have this standard of connectivity. For example, you can use it without problems with a Garmin 220. But what makes it special is that through a second channel transmits information needed to compose the race dynamics (Running Dynamics) that shows us the clock both at the end and synchronize the activity, and directly on the screen if we have so configured. Then I will talk about this more extensively.

Garmin Fenix 2


I usually start the tests by analyzing how the watches behave while running, and in case I include some navigation mode I will detail it below. This time I will do it the other way around, precisely because the Garmin Fenix 2 is "upside down". Before being a sport GPS watch, it is a mountain tool. Therefore it is when it comes to mountain adventures where the Garmin Fenix 2 takes more prominence.

The Fenix 2 has been built on the foundations laid by the original Garmin Fenix, but has been given all the functionality of the Forerunner range. We might even see it as a triathlon watch, but first let's see how it performs when it's time to take us from one place to another when we're in the bush, and then we'll look at other uses.

When it is time to start sailing, the clock will present us with several modes to choose from, as we can do it in several different ways



A waypoint is a point that you can manually save, either from the clock while you are making a route (by pressing the DOWN button), or from any of the applications, and then synchronize it with the clock. This allows you to navigate without a predefined route, for example, or to return to a point that you have left marked.

To give you an example, imagine you are on a wide plain with no vegetation. There would be no point in navigating from a route here, as there is no marked path for you to follow. You simply select the location you want to go to, and go looking for it.


The route is created as a succession of waypoints. You follow each location, one by one, until you reach your final destination. It's like following a path of breadcrumbs. You can create these routes from Connect or from BaseCamp and then synchronize them with the clock.


A track is the recording you have made of a route, or one that you have been able to download from the Internet (for example, from Wikilocs). The difference with a route is that they are files that have more information at each point and, generally, many more waypoints, since if, for example, you have the GPS configured to record data every second, with each data saved it would create a waypoint and therefore a new point within the track.


You can enter the coordinate data directly into the Fenix 2.

Sight n' Go

You would point your watch to your final destination, and it would be saved so that you could go to it. Imagine that you crown a mountain and on your way you see a small lake inside a forest, but you can only see it from the crest of the mountain. You can mark that direction so that once you are inside the forest, you can guide yourself until you find it.


Trackback Fenix 2

At any time you can use the TracBack option, to return to the starting point. This will be active whenever you have developed an activity with the GPS connected. It allows you to return to the starting point of the route and will show you the way to follow.

Navigating. Maps and zoom.


When navigating, we can add a screen to display the map of the route. By default, the Garmin Fenix 2 does not include a map to display the information. This is how we can see our complete route.

Zoom plane 3km

Of course, it is possible to get closer to see the map and to better understand when we should take a detour, or see if we are on the route.

Zoom plane 120m

Whenever we are sailing we can add one more screen to the clock where we can receive information about the distance we have left, the time it will take to cover it taking into account the current pace and what is the approximate time of arrival.


In addition to showing us the navigation only through the route, we can add some basic maps on which we can move to help us in the orientation (although sometimes it can cause more confusion than anything else). These maps are thanks to the communityas it is not an officially supported feature of Garmin, and not even announced.

Plan in Fenix 2

Personally, with the size of the screen and its low resolution, I don't see much interest in adding these maps. When navigating through the mountains on a route, it's more than enough to see the track that the clock itself prepares, because seeing the way the road moves allows you to clearly identify where you should go. Not having a color screen that allows you to differentiate which is your path and which of the lines shown is the one you should follow doesn't help at all.

Creating Routes

There are several options for creating a route to navigate with the Fenix 2. Garmin ConnectYou don't have to install any program on your computer and you can sync the route from any device. There are other options, such as BaseCamp, but you have to download the program, install maps and it's a bit more complicated to use.

Once you enter Connect, simply open the menu on the left to select "Paths" (the last menu option)

Connect Journeys

The great advantage of doing this through Connect is that we can do it with Google maps, both "map" and "satellite" maps, which are much more familiar to the vast majority.

Plan 1

Creating a route is very simple, you just have to create waypoints and they will be automatically linked. In the menu on the right we have access to all the data, the most important one being "stay on roads". With that option selected we just have to put a waypoint in each of the road junctions you find. But if you want to make a route on a road that is not marked as a road, like a path that is seen in the satellite image, you just deselect that option and put the next waypoint.

By playing with these options, you will create your route. As you put in points, you will have information about the distance of the route, as well as the height of the route with its profile. By entering an average pace, you will also know how long it will take you to do it.

Montemayor Castle

In this route I have used a little bit all the options. I have started following the path of a river, so I have had to deactivate the option to stay on roads and I have created more waypoints. Once you arrive to a road, you select again the option and with only 5 or 6 waypoints you create a quite long route, until you arrive to a new point where you deviate from the road and you would have to make a climb by a small path, then you create again multiple points.

Once back in the village, just select "Loop with start" and it automatically finishes the route where you started it, creating a circular route and through the shortest path. Preparing this route has taken no more than two minutes, it is a very easy way to set up your trail breaks.

Once you have finished you can save the route and then click on send to device, selecting your Fenix 2.

Send to Fenix 2

So as soon as you sync your watch, you have your route available for navigation. You don't have to do this via Garmin Express, from your own phone you can also sync your route

Data Synchronization


If the Fenix range has advanced at all (both the Fenix 2 that this test is about and the original Fenix that has been updated and improved) it's in its running GPS watch facet. Originally the Fenix development team (which is different from the Forerunner range) was totally focused on the navigation and GPS tool side. But this has totally changed with the Fenix 2, which has added many of the options that we can find in its branded "cousins", such as the Forerunner 620. In the Fenix 2 we'll find things like Running Dynamics, interval training, VO2max and race time prediction, and many other things. Options that we're used to seeing in running watches and that many will be happy to see incorporated into the Garmin Fenix 2.

But let's start at the beginning. As with any watch created for running, GPS is very important, not only during the activity but at the beginning of it, in the time it needs to get a satellite signal. In the case of the Fenix 2, Garmin has a built-in GPS cache function. Every time you synchronise your watch, either with your phone via Bluetooth or via USB with your computer, Garmin Express (or Connect if it's on your phone) will download satellite positioning data, which will help the watch in the initial search and reduce the triangulation time.

This happens when we start the activity, so after pressing the Start button and selecting Run (or whatever you have called it if you have changed the name) the clock will go to search for sensors. First it will search for the pulse sensor, and then it starts with the satellite search. As always, I leave you a video of a search so you can check how long it takes to find them

And once we get a satellite signal, the Fenix 2 is ready to go.

Shortly after starting to run the Fenix 2 will show you an alert. It usually warns me shortly after I have passed the first kilometer, although I suppose it is a coincidence along with my pace

Level of recovery

The Fenix 2 calculates how you have recovered from your previous workout based on your heart rate variance (HRV). The watch processes the data from your previous workout, analyzes the heart rate variance in the current workout and determines the value so you know how you can exercise in this session.

Is there science behind this? I guess, because this data analysis is not a Garmin thing, but it's licensed through the company FirstBeat, specialist in pulse analysis and calorie calculations. So they know something about it. FirstBeat is also behind other functions of the Garmin Fenix 2, like the V02Max, the race forecast, recovery advisor and the training effects (I'll leave it for later).

As always, when training it is important that the clock is able to register changes in rhythm quickly, because if you are doing intervals you want the clock to show you real information at all times. Instead of saying that it is getting better or worse, I find it more appropriate to show you a video where you can see for yourself what that variation is like. I start walking, to move to a moderate pace and then walk again. Again I start running, accelerating little by little until I reach a slightly faster pace, at which point I stop in the dry.

Once we are in the race, in the Fenix 2 we have access to a lot of data, which we must previously configure from the activity configuration menu (which can be reached by pressing the menu, configuration and activity button). Here we find a series of activities that are pre-configured in the factory, such as cross-country skiing, climbing, open water swimming, swimming pool, etc. We can also configure three more profiles, which you can call in any way you like.

The purpose of all these profiles is that you can configure the data screens separately for each of them, because obviously you don't need the same data on screen when you swim or ride a bike.

Page Setup

There are different ways of displaying the data on screen, with a maximum of data per screen. Additionally, there are special screens with graphics, such as the height screen, or pre-configured pages like the one in Running Dynamics.

This is a page with four pieces of information

4 dataWith three

3 dataWith two

2 dataAnd with only one

1 fact

And the data pages that are special, like heart rate

Heart rate display



Or altitude, among others


You can configure the screens that you want and in the order that you want, and remember that they are independent for each sport. So for example for racing you can make a page with only two details such as pace and pulse, in large to make it easier to see, and then another screen with more values that you will access less often.

There are other settings for each activity, and remember, we can configure the alerts in each of the profiles.


Garmin Fenix 2 Alerts

  • Heart rate: with minimum and maximum, or directly one zone. It will alert you if you go outside the marked range.
  • Running / Walking: you select time to run and time to walk, and it lets you know when that time has passed.
  • Rhythm: warning to be in a rhythm range.
  • Time: Marks an alert that you set from a certain time.
  • Distance: this is divided into interval, final distance and trip deviation.
  • Cadence: minimum and maximum cadence, if you go out of range you are warned.
  • Calories: warning when a certain calorie consumption is reached.
  • Proximity: you can program a warning when you are within the distance you determine from the point you previously recorded.
  • Altitude: we have four variables: minimum, maximum, ascent and descent.
  • Nav. to goal: safety alert - You will be warned when you reach intermediate or final points on a route, so you don't get lost and know when you have reached your destination.
  • Speed: you select a minimum and a maximum, and you will receive a warning if you go outside that range.
  • Battery: The Fenix 2 will alert you if you have less than, say, a 20% battery. The percentage is configurable.
  • Ignition: don't be fooled, it's a mistranslation. It refers to power, for cycling profiles.

All of them are alerts that you can activate or deactivate at any time and for any sport profile, and the moment something happens to alert you, it will show you the notification and it will do it the way you want (vibration, tone, both or only on screen).

Notification of fins

Here for example I have programmed an alert to warn me if I go slower than 6:30 min/km.

Lower Rate Alert

It is not a training program like the ones you can program, but it can help you develop another type of training or career.

I'll give you an example. You want to complete a half-marathon at a maximum pace of 5:00 min/km, but you don't want to get burned out either and you want to know when you can start squeezing, in case you even want to improve your target pace. So, to start with, you program a Virtual Partner with your pace (and add the screen to your running profile), you activate a pulse alert so that it warns you if you exceed, what do I know, 165 ppm. That way you can be sure not to get burned out too early. And finally you program an alert for proximity to 3km from the finish line (in a straight line) and you can know that from that point on you could give it your all.

Well, like this example, as many as you want and as far as your imagination will take you.



If you want the Fenix 2 to create an autolap, you can configure it from here. By default it is set to 1 km, but you can change it to any value you want, from 9,999 kilometers to 0.01 kilometer.


Perfect for running in the city where you're going to meet traffic lights, or on trail where you might stop more often to take off or put on your jacket, or riding your bike for when you get a flat tire and have to stop to change it. Simply stop the recording of the activity if you stop.

3D speed

Correct your speed with respect to elevation, i.e. if you are running or cycling on steep slopes, the Fenix 2 will correct for the value. Imagine that you are cycling up a slope of 60° (yes, that's a lot to imagine). If your speed is based only on latitude and longitude values, i.e. in 2 dimensions, it will give you a lower speed because it is not doing the calculation correctly by not taking the slope into account. Then when applying the 3D correction the clock will do the correct calculation.

3D distance

Same example as above but with the distance. You walk 2 km on the flat and then 2 km with a 45º slope, if you don't apply the 3D correction the clock will register less distance travelled, because in LAT/LONG points the space travelled is less. In short, everything is based on the Pythagorean theorem and the length of the hypotenuse (which would be the two km uphill).

Data Recording

You have two options to configure, smart mode or every second. For the runners, you will be interested in the per second mode since you will have the values at the moment. For activities such as walks in the field the smart mode is the most indicated, since the clock will be the one that chooses the moment to make the data recording.

GPS mode

The Fenix 2 allows you to choose between normal mode or UltraTrac mode, which I will discuss at length in the section on range.

Virtual Partner

Virtual Partner Garmin Fenix 2

You can set your target pace or speed and compete against that "virtual colleague". In addition to activating the sport profile function, you must also add the screen among those selected for the profile to show it to you when you perform the activity.

Automatic scrolling

Switching between screens automatically

Finally, you can find another option to show or not show this profile you are editing in the sports selection menu, that is, at the moment you press Start to start an activity. Therefore, if you do not climb or ski, you do not have to see it in the menu every time you start an activity. You can leave it hidden and leave visible only the sports you are going to practice.

Running Dynamics

The race dynamics works thanks to the HRM-Run pulse sensor. It gives you information about how your race is, starting from 3 values:

  • Speed: Steps per minute, depending on the running technique values, the ideal figure would be 180 steps per minute.
  • Vertical displacement: The distance you move up and down when you run. That is, your bounce on the ground. The greater that distance, the worse your running performance,
  • Ground contact time: The time the foot is in contact with the ground. The shorter the time, the faster we go

To understand these values, there is nothing better than an image, and I have a good example of a workout where there are values of all kinds, because I start well but soon I slow down, and I even have to stop running and walk through a digestive cut.

Running Dynamics

The picture has everything, and it speaks clearly of how the race went. The heart rate graph helps to understand every change.

You can see that I start at a good pace, with a high cadence and a short contact time with the ground, but as soon as I start to slow down to about 150 beats, the cadence drops and the contact time increases (obviously, the pace is lower). As soon as it is time to stop and walk, the beats drop, the cadence drops and the contact time increases, but consequently the vertical oscillation is in the protruding area, as there is hardly any bounce when walking.

As you can see a lot of data can be extracted from here. We can also look at it together with other graphs (height, pace and temperature), so you can perfectly analyze why your pace has changed and it will help you to better understand your running performance.

You can also add a screen to your running profile, so you can polish your technique while running.

Running Dynamics

Once you have the screen selected you can change the main value (the one shown above) by pressing the menu button for one second.

Change Running Dynamics

We select another value and that will be the one that appears as the main value

Running Dynamics

In addition, the external part of the screen will be transformed into a "rev counter", as if it were a needle, and will show you graphically where you are.

Running Dynamics Garmin Fenix 2

The question is... are these data useful for anything? To a certain extent, I think so, but some more than others. I don't know to what extent we can take the values as absolute, because I think they will depend on each runner, not only on their athletic level but also on their height. I think that a cadence of 180 ppm is not the same for a 1.60m runner as it is for a 1.97m runner like me. The same goes for vertical displacement.

Buscador de chollos

What is not very well founded is the time of contact with the ground, because it is pure logic. If you go fast, you spend less time touching the ground than if you go slowly.

So, as you can see, as soon as I tell you one thing (which is useful data to understand your performance) as the opposite (which is not all that nice anyway, because in the end it depends on other factors as well), I think that at popular levels it can be more valid for analysis as a curiosity than as a real utility, although at professional levels it can mean an important change. That is, if, over time and if you are in the process of changing your career mechanics, this data can be very useful since you will be able to compare results between different trainings.

All this doesn't change the fact that you have to train your cadence (something I have pending) and, so that you can see its true incidence, I would like to tell you that an elite marathon runner has a cadence of about 200 ppm, so you can get perspective...

VO2Max and career forecast


The Fenix 2 calculates your VO2MaxOf course, if you want to know exactly what your VO2Max is (i.e. your aerobic capacity) you should do a full stress test. But as an approach it is well done.

This value depends on each individual athlete, and it is not common to see it vary frequently, especially if you have been training for years. If you have been a pro on the couch and are starting now, then you will see your improvement, but once you have reached your aerobic level you will usually not see much variation unless you vary your workout quite a bit.

Thanks to the VO2Max calculation, the Fenix 2 will also offer you a race prognosis, a table that, taking into account your aerobic capacity, age and sex, will indicate your target times in different events, or at least the times that other athletes with similar figures can achieve.

Race Predictor

It doesn't mean that if you don't get those times you're doing wrong, because it doesn't take into account the training you've been doing or what test you're preparing. Take it as a future goal, something you could reach if you keep training and your body is capable of achieving.

The Fenix 2 will also inform you of your recovery time after a workout, or by entering your own section from the menu. The watch gives you an estimate of the time you should wait before planning your next high-level workout, with the idea of not overtraining.

Recovery advisor

It doesn't mean that you can't do any sport in the time period marked by the clock, especially considering that this value will only be affected by the runs you do, since we won't be able to find it in any other sport profile. Everything you do in swimming or cycling won't change the recovery time (like the rest of the ratings such as VO2Max or race prediction).

Post-training information

At the end of our training we will have access to all the data of it (and at any time through the menu of History). Among the data that we can find we will have duration, distance, average pace, etc. In addition we have access to data for each of the laps that have been marked manually or automatically.

Summary of activity

It also shows "Training Effect" information, which measures the impact of the activity we have performed on our aerobic condition.

Training Effect

This value depends on your personal profile, the exercise performed and the heart rate during the exercise. Again, it requires some learning time to understand you better as an athlete and to be able to give you more appropriate values. Garmin provides a table so that you can compare the result obtained and know how you have trained.

Values of Training Effect

Training sessions

In the Fenix 2 you have several options when it comes to training and setting your goals. We are talking about interval training with automatic alerts, because obviously you can always do a manual workout where you set your lap times manually and look for the goal as you wish.

Firstly, you can create a session directly from the clock by pressing the start button and scrolling to training sessions.

Training sessions in Fenix 2

Here you will have the previously synchronized sessions, the training according to calendar that you can create or an interval session that you can modify directly from the clock

My sessions

This last option is not intended for you to create a series of workouts and save them. It's more like a quick menu where you can configure an activity, so when you enter the menu you'll be editing the last workout you created from here.

From this menu the creation is very simple. First you enter the work interval, then the rest time and the number of times you are going to punish yourself with these intervals (the number of repetitions). These values can be in distance, time or "open", where you will mark the laps freely, normally at the moment just before putting the liver in your mouth. Finally you can establish some warm-up and cool-down times.

Editing trainings in Fenix 2

As an option to create a quick workout it is very valid, and it is a good option if you have not planned anything in advance and want to do something fast. In this case we cannot select the target of the intervals (to stay in a range of pace or heart rate). To do it that way, we have to create it from the computer through Garmin Connect. These workouts will be stored in the memory and will be accessible from the clock any day you want to repeat them.

As with manually created training, you will set up warm-up, cool-down, how you want intervals and recovery intervals, which you will then repeat or not.

You can do a basic training without any objective where you will mark the rhythms you want

Or seek to achieve and maintain certain rhythms.

Garmin Connect Pace Training

Once you have created and saved the training sessions, you can send the training session and you will find them in the training sessions menu. It is therefore important to give a name to each session so that you can identify them quickly.

Synchronized session

Once you are training, the watch will mark the steps as you progress in your workout, indicating what period you are in (warm up, recovery or interval, in which case it shows you the target), and the duration or distance to be covered. In this case, it asks me to run for 1 km at a pace between 5:15 and 5:25.

Fenix2 showing interval

But don't worry, you don't have to keep an eye on the clock screen. If you get too excited and run more than you're supposed to for that stretch, the Fenix 2 lets you know

Higher rate Fenix2

Just like if you go too slow looking at store windows, it will also warn you that you are going below what you had planned.

Fenix2 lower rhythm

As you can see, the training development is very complete, but I recommend that you know beforehand what you have to do in each interval, because with the screen resolution of the Fenix 2 it's quite difficult to see what the target time is while you're running. I, at least, have a hard time with it.

Running indoors with the Garmin Fenix 2

With the Garmin Fenix 2 you can run not only on the street, but also indoors (on a treadmill or in an indoor track). And you can get the rhythm and distance data in two different ways. On the one hand, the way we are used to, by connecting a foot pod through ANT+ and placing it in one of our shoes. From the sensor configuration menu you can add it very easily.

Foot Pod

But in the Fenix 2 you have the possibility to run only with the watch on your wrist, and you will have the calculation of rhythm and distance thanks to the internal accelerometer of the watch. To do this, the watch has a learning function that will take data as we run outside with the GPS activated. When you buy it you have to know each other. You have to know how to use it, and the Garmin Fenix 2 will have to know how you run. That way you will be a perfect couple.

And the more miles you run with the watch outside, the more it will know about your running and give you more reliable data, so don't expect to take the watch out of the box and run on the treadmill.

But it's not enough that I tell you this is so, period, I test it and you make sure it works the way you want it before you buy it. For the test, I'll take a Garmin 620 with the GPS activated that will set the tone.

Running indoors with Fenix 2

I did a short race starting at a steady pace and then trotting to gradually increase the pace, and thanks to the Garmin Connect graphics, we can analyse the result.

To begin with, let's look at the distance measured in each case. I remember that the Garmin Fenix 2 has its GPS turned off.

Garmin 620 Comparison

Garmin Fenix 2 comparison

The Fenix 2 has calculated 1.67km while the 620 has marked 1.81km. 140 meters between both means less than a 10% difference that I consider a quite positive result, since it is making the calculations exclusively through the movement of my arm.

Now we are going to compare the rhythm graph, in blue the 620 and in red the Fenix 2. There is a strange jump at the beginning of activity in the 620, but from that moment on the graphs are very similar. Even in the case of the 620 the graph appears slightly corrected, with less abrupt changes, while the Fenix 2 picks up the change of rhythm before the 620.

Garmin, Fenix 2 vs 620 comparison


So the Fenix 2 makes a fairly accurate approach to running indoors, and you can keep track of your indoor training with this Garmin utility.


Going by bike

In the Garmin Fenix 2 you will find a specific cycling profile, which means that you can set up the screens for the sport profile completely independently from the other activities (for example, setting the speed information to km/h instead of min/km).

So far, more or less what many other watches can do, but where we find the real differences between what the mid-range models offer or what we can find in high-end watches, as is the case of the Fenix 2, is in the external sensor support.

Speed sensor

The Fenix 2 allows us to pair up the watch with a multitude of ANT+ sensors. From speed or cadence (or speed/cadence) sensors, to single crank or left/right power sensors. In addition, when you connect a speed sensor you can tell the Fenix 2 when to take information from the sensor, whether only indoors or at all times. Therefore, we can find an indoor cycling option, to train on a roller and disable the use of GPS automatically.

On screen we can select, as in the rest of sports, all the data we consider appropriate and with a maximum of 4 data per page. You can place the watch on the handlebar with a suitable support, or wear it on your wrist as you usually do. In this case I would recommend not putting too many fields on each page, if you want to have a quick readability of the data (no more than 3).

As you may be used to see, in the clock we can get the instantaneous speed directly through GPS data. In the case of the Fenix 2 I found it a bit slow when updating the speed, so if you are going to use it frequently to ride a bike I would recommend you to get a speed and cadence sensor, that way you will get the speed directly from the sensor, being totally real at all times (as long as you set the wheel measurement correctly).

I leave a video for you to judge for yourselves whether or not you need an external sensor for your use.


The Garmin Fenix 2 will give us two options when it comes to getting in the water, swimming in open water or in a pool. This has been an important addition to the Fenix 2, something that the original Fenix does not enjoy. However, we still do not have the possibility of obtaining pulse information, something that Suunto and Polar have already been able to solve in different ways but that Garmin still does not contemplate in their watches.

Open water

Fenix 2 in open water

By open water, the Fenix 2 refers to any water activity that does not take place inside a pool. That is, if you swim in a river, lake, sea or watering hole, you should use this mode. Anything that is not inside a pool with a certain size and that is in the open air.

Due to the time of year we are in and the lack of a wetsuit (I remember that I am mainly a runner and I don't have more typical triathlete material) I haven't been able to test exactly the benefits of the Fenix 2 in the sea.

In this case, the Fenix 2 will use the GPS data, but before continuing I would like to remind you how the satellite signal works. Every time the watch enters the water (that is, with every stroke) it will lose the GPS signal. This is a complicated way to implement for all manufacturers, because as they do not have a continuous signal, the watches must apply a correction algorithm to determine which is the route that you have followed at each moment, because if you do not do it, the activity plan will jump continuously.

In addition to the GPS, the watch will also take data from the internal accelerometer to record other information, such as strokes per minute.

Of course, the data pages can be configured with values specific to swimming, with specific information on distances and strokes. All data is treated in a way that is specific to the sport in question.

In the case of swimming in open water, we must give greater margin of error to the distances offered, since by losing and recovering satellite signal continuously, the data provided will be more of an approximation, so you should not take the distances covered to the letter.

Swimming pool

Fenix 2 in pool

In the swimming pool mode the GPS will be completely disabled (even if you are swimming in an outdoor pool) and all the information will be provided by the internal sensors of the watch. Information such as distance and number of strokes

You will get the distance because before we start swimming we must enter the data of the size of the pool. Then the Fenix 2 will be able to identify when we are doing a stroke and when we have reached the end of the pool. At that time it will know that we have completed a stroke and we are starting a new one.

The size of the pool can be selected directly (e.g. 25m or 50m) or the distance can be entered manually.

In short, all the information that the clock records is based on the movement, both strokes and the time to end a length and start a new one. So the recommendation that Garmin gives us is that the movements are energetic, so that the clock is able to record all the events in a satisfactory way. That is, at the end of the length it turns around decisively. And if you meet a friend from the institute three streets away and want to say hello to him, put the clock on pause or you will "dizzy" all the records that you are making.

The watch will also give SWOLF data, which is the sum of time in making a long stroke plus the strokes needed to do so. The acronym comes from swimming and golf, and as in the latter sport, the lower the number of strokes, the better the level of your game.

Within the activity's own configuration we can also set alerts, based on distance or time, and at the end of the activity we can always return to the clock to check how the session went.

Swimming 1

And you will be able to analyse, just like in a race, all the exercise data: time, distance, calories, average pace, total strokes, average length and finally the average SWOLF of the swimming training session you have just done.

Swimming 2


And remember, when you synchronise your watch, you'll have all the details of your workout in Garmin Connect - data such as distance, pace and SWOLF.

Fenix 2 pool times

You will have access to the splits or laps, which will also reflect the breaks, if you do so (in this case I didn't do any). You will also be told the number of strokes and the swimming style.

Garmin Fenix 2 Swimming Splits


And since man does not live by numbers alone, you can also expand the data graphs, which of course you can compare between them.

Fenix 2 Comparative Swimming Chart

Multi-sport mode

Dear triathletes, this is the point that many of you wanted to reach. Yes, the Fenix 2 has a mode called multisport, which is commonly known as Triathlon. But duathletes, do not feel discriminated against, because at Garmin they have also thought of you and you can also use the Fenix 2 in your competitions.

The way to work with this mode is really simple. Once you enter the multisport menu you will be able to select which activities you are going to do, and therefore leave prepared which pattern you will follow. The most typical will be the swimming - cycling - running

Triathlon in Fenix 2

But as I say, it doesn't mean you can't think about signing up for other disciplines, like cross-country skiing, and then jumping in the water to swim. Very refreshing.


When it comes to displaying sports, it will display them individually, both on the screens shown on the watch and when synchronising with Garmin Connect. So in swimming you'll have the screens set up for swimming and in cycling or running you'll have your own. You can also activate the one that includes the transition times from one sport to another.

Transitions in Fenix 2

Therefore, it is not a specific sport profile, but the union of two or three profiles. But using it in this way you will have the advantage that the activity time will count from the beginning of the competition and you also gain the possibility to know the transition times.

Internal sensors

Configure Sensors

In the Garmin Fenix 2 we can find a series of internal sensors, for the use and delight of the most adventurous. In the case of the Fenix 2 we are in front of a clock that is commonly known as a GPS + ABC clock, that is, with altimeter, barometer and compass. And to this we can also add an internal temperature sensor.

Barometric altimeter

Fenix 2 sensors

The first thing we want to find in an adventure watch is an altimeter. This way we will be able to know the altitude data in a more real way, because in GPS watches without this feature the altitude we get is the one given by the GPS, which is not very accurate, or at least not the one a mountaineer needs. However, if during the training you do not consult the altitude it will be worth this system, because normally after synchronizing the activity all the programs already have this value corrected, so when analyzing the data it will be more or less correct.

But if you're in the middle of a mountain, the altitude data will be relevant at the time, and depending on how your screens are configured (even if you're not recording activity you can still access this information), you'll have the current altitude data as well as a graph of the elevation you've been going through.

The altimeter can be calibrated, either automatically at the beginning of each activity, you can set it to be continuously calibrated, or you can do it manually, for example if you are at sea level or if you are at a point where you know exactly what the actual altitude is.

Let's remember that this is a barometric altimeter, so its operation is based on the relationship between pressure and altitude. As the atmospheric pressure decreases with altitude, its exact operation is conditioned by the weather changes. Not that this is bad, is that the other option is to put a radio altimeter, which comes to be a radar. And maybe it is a little excessive to carry on your wrist ...

The barometer, besides being able to calculate the altitude, is also useful in predicting the weather. In fact it is possible to set a storm alarm based on the drop in air pressure in the last three hours. It can be set to warn you if the drop is between 2mb and 6mb, in 0.5mb intervals.


That is, if you set it to 4 mb / 3 hrs, if the air pressure changes from e.g. 1010mb to 1006mb in less than 3 hours, the Fenix 2 will alert you in the way you indicate (tone, vibration or both).


The Fenix 2 has an internal temperature sensor, not that it is very practical in normal use and if this is important to you I recommend the Garmin Tempe external accessory (which I will tell you about in a moment).

The internal sensor can be useful if you want to know the approximate temperature, because when you wear it on your wrist it will be affected by body heat, although if you use the Fenix 2 with the fabric strap over a jacket you will be able to record more real temperatures, as it will not be in contact with your body.

The question is, does it really work well? Well, there is nothing better than putting the clock in a controlled environment where we can know exactly the real temperature, so that we can evaluate the accuracy of the sensor. Looking at the kitchen, it occurs to me that I can check it by putting the clock in the oven at 200ºC or in the fridge at 8ºC. After evaluating it carefully, I choose the second option, so I send the clock to the fridge, on top of the yoghurts (so that it is not in contact with metal parts, normally colder). And here you see that after a while locked, it marks 8ºC.

Garmin Fenix 2 in fridge

This is to check that the thermostat on my fridge is working perfectly.

Refrigeration temperature

But in addition to this internal sensor, as I mentioned Garmin sells an external accessory that connects via ANT+ and is called Garmin TempeIt is priced at £30 and in addition to sending the actual temperature to the clock (and other compatible devices) it also stores the temperature data for up to one year.

Tempe Garmin Fenix 2

It has the same format as the Foot pod, and in fact the support is the same. You can wear it on your shoe laces or put it somewhere like your backpack, so you avoid it being in direct contact with your body and confusing your reading.

Garmin Tempe

Magnetic compass

Finally there is the magnetic compass, very useful when making navigation routes. Unlike the digital compass, with the magnetic compass you do not have to be moving in one direction for the clock to know where to mark the north. You can be still and rotate, the clock will continue to mark correctly.

When navigating with the Fenix 2 the use of the compass is important and it will make your task easier. Not only will it change the way the compass is displayed by an arrow, indicating the way to go, but it also adds the two marks on the outside of the screen that you will have to align with the mark on the top of the clock (above where it says Garmin).



The Garmin Fenix 2 is more than just a GPS clock for running, it is a tool. And as a good tool, it has several tools (worth the redundancy) for all kinds of uses, from the most adventurous to the simplest. Among the most typical we can find obtaining data from satellites, mark points or see what is the current route. But there is some other tool that surprises, like these I put you below.

Sun and moon

Sun and moon

It tells you the time of sunrise and sunset, through the information downloaded from GPS. Very useful if you are in the middle of a route and want to know when to start looking for a camping area. It will also tell you what phase the moon is in.

Hunting and Fishing

Hunting and fishing in Garmin Fenix 2

Bear Grylls style. Imagine being thrown into the middle of a forest, with no food, and you have to go and get it. Well, the Garmin Fenix 2 will give you a hand. Not that it will make your food, but it will tell you the best times to "go and get it". It's based on the Solunar theoryYour attraction to the refrigerator in search of food (or beer) does not correspond with this theory, although it coincides with the times shown in the Fenix 2.

Area calculation of an area

Suppose you want to measure a certain area, but it's not a square, and you don't feel like doing complicated calculations or using topographic maps. Simply activate this tool, walk around the perimeter of the area of interest and the Fenix 2 will give you the total area. Easy, right?


Are you a skydiver too? You're a box of surprises. Well, don't worry, because at Garmin they've thought of you too. There are three modes for skydiving, HAHO (high altitude, high opening), HALO (high altitude, low opening) and Static. What's the difference between the three? If you're a skydiver, you're bound to know it. And if you're not, you'll have to find one to clear it up for you.


It's the acronym for Man Overboard, meaning man overboard. Think of going on a boat and throwing someone overboard. You can mark the position where you've thrown him, so you can come back and get him later. It's also a very useful feature if you want to run a successful drug transport business.

Battery life

Taking into account the type of user this watch is aimed at, it is clear that one of the most important things will be autonomy. And Garmin has taken this into account, providing the Fenix 2 with a fairly large lithium battery, with 500mAh capacity. And it is not only that the battery has a large capacity, it is also that you can configure different modes of use of GPS (which is what produces more consumption in the watch). We can record data every second, which is the usual. This includes data taken from GPS as well as other sensors that we may have connected to the watch, such as pulse sensor, cadence, speed or power. This would be the Normal mode that appears on the watch, and according to indications from Garmin is capable of recording up to 16 hours in a row.

But also from the activity menu (and configurable for each activity independently) we can modify the interval in which to record data in order to increase the total autonomy. According to Garmin data, with a data update every 15 seconds the clock will give us an autonomy of 20 hours, and doing it every 20 seconds would be more than 24 hours.

GPS Recording

And if in spite of all this you still run out of battery power, you can opt for a third mode which is UltraTrac. It will record GPS data every minute and will not record anything from ANT+ sensors. In this mode of operation it can reach up to 50 hours of recording in optimal conditions.

Among the battery tests I have done, I can tell you that a few weeks ago I was on a trip to Disney. To begin with, I did the complete "track" of the flight, with a duration of 2h23m. The next day I did the recording of the whole day we spent in the park, a total of 9h23m. In both cases the recording was in 1 second mode. After these two long duration tests, and with the normal use of the watch for a few hours, as well as synchronization of the airplane route via Bluetooth to the phone, the watch still had more than a quarter of the battery left. Impressive results.


In the case of the Garmin Fenix 2, the clock's illumination is red. Within the configuration menu, there is a specific one for the illumination.


We can regulate the lighting intensity in increments of 10%, we can change the time it stays on when we press the button dedicated to the lighting (5s, 15s, 30s, 1m or 2m), as well as disable the automatic switch-off function, that is, we turn the light on when we press the upper button and it will stay on until we press it again.

Garmin Fenix 2 lighting


There is a third option, which is the automatic illumination. You can leave the automatic illumination on, or only from sunset; and it will remain on for the time you have previously defined. It will be activated when there is an alert or you press a button.

Garmin Fenix 2 illuminated display

Daily use clock

Fenix Clock 2

In addition to using the Garmin Fenix 2 as your training watch, you can also use it on a daily basis (and use it as a smart watch! I'll talk about that later). You can set up the display in many different ways, changing the information that appears next to the time as well as the "second hand" effect that borders the entire watch face, as well as having additional information such as sunrise and sunset, the day or date, or the remaining battery. You might think that the information offered by the watch is another page of data, and as such, you can set it up to your liking.

Setting Time Display

You can also program alarms, and more than one. They can also be recurrent (i.e. sounding more than once) on a daily basis or only on weekdays, and can alert you silently, by sound, by vibration or by sound/vibration together.


Bluetooth Fenix 2

You can connect the Fenix 2 to your computer with the USB cable it comes with, which is also suitable for charging. This is the connection you will probably end up using by default, both for syncing with Garmin Express and for charging routes with Garmin BaseCamp or those you create from Connect. This is because it is the easiest and quickest way, and you can also charge your watch from your computer while you work on analyzing the downloaded data, checking or preparing a route through the mountains, or simply leave it connected and charging.

But in addition to the cable, the Garmin Fenix 2 lets you connect wirelessly via Bluetooth to both the Android and iOS Connect applications. In order to make use of this functionality, your phone must have Bluetooth 4.0.


The truth is that synchronization takes a long time, you even wonder if the phone has hung up, the clock, both or if you want to hang up while you wait. This waiting time depends on the amount of data you have pending to synchronize. But it is an option that is there, you can take advantage and if you do not have a computer at hand can save you in more than one situation. What takes longer is to transfer the cache with the satellite data as well as data from longer activities, because they are larger files. But on more than one occasion can save you from a rush and if you do not have access to the charging cable at that time will be grateful to have the possibility.

Fenix 2 Bluetooth

And thanks to this Bluetooth connection, you can also broadcast your workout or race live to anyone you want, just send them the link. Garmin calls this Live Tracking, and what it does is broadcast your location to the Garmin Connect website and that's where your friends can connect to follow your workout, as long as they have the link to the activity. You can provide this link privately via email, or you can post it on Facebook or Twitter and give all your followers a chance to see your workout. And I can think of many possibilities for this option:

  • Elite athletes who want to have more contact with their social network followers. Imagine Kimetto broadcasting some of her workouts, I'm sure her Facebook followers (if she had any) would be happy to see it
  • Less elite athletes (like you and me), who like the family to encourage us in long runs, can know where you are so they can go there to encourage you and once you have passed, go and find the next meeting point.
  • Follow up your training by a coach. He doesn't even have to be in your town. He sets up a training plan for you and can do live training analysis, even for several athletes at once.
  • Going out on a mountain route so that your family can see, for their peace of mind, that you haven't got lost. Of course, for that you will need a satellite phone, because if you have coverage on your mobile phone, you have certainly not gone far.

To make use of this option you must carry a phone with you, because the Fenix 2 does not have 3G connectivity (there are some watches that have this option, but it is not common, especially because of complications with different operators in each country). Sounds good, right? Well, now comes the catch, and is that the use of Bluetooth can not be simultaneous with the use of ANT +. This is something specific to the Fenix 2, because with the Garmin Forerunner 620 or 920xt this does not happen and you can use Bluetooth simultaneously with ANT +.

Garmin Connect LiveTrack

So, since there is no simultaneous use of Bluetooth and ANT+, you have to choose if you want to do a LiveTrack session or if you want to have information from the sensors paired with the clock.

Finally, you can also turn your Fenix 2 into a smart watch, receiving alerts from your phone on the watch screen. Simply pair your phone with the watch, leave Bluetooth on, and activate notifications from the watch menu.

Fenix 2 Notifications

From that moment on, you can receive notifications on your phone. It doesn't reach the integration level of, for example, Android Wear, but it can certainly help, although obviously the autonomy will suffer and you will have no choice but to charge your watch more frequently.

Garmin Fenix 2 Notice

Garmin Connect

Garmin Connect is the trunk where everything we do with the Fenix 2 will go. This is the page where we can analyze the data of all our activities, as well as schedule workouts, routes, see personal records, check how other friends are training and much more.

As soon as you log in to Connect, you'll have access to the complete control panel, with all the information available at a glance.

Garmin Connect 1

On the left side you have the complete menu that will give you access to all the different options. Activities, calendar, segments...

Connect Journeys

Under that menu you will have the inbox in case you have messages, the data to be synchronized (training sessions or trips, for example) and finally the section of your profile where you can modify all your user data as well as information regarding how you want the information to be displayed.

You can enter the section of activities to see all the ones you have done and synchronized, with a small reference information for each of them with specific data according to the profile, such as swimming data.

Garmin Connect Activities

Entering each one of them you will have access to a multitude of information, in figures or in graphs. You can customize which graphs you want to see and passing the cursor through each one of them you will be able to have more exact data, both from that graph and the upper or lower ones. In the lower part you have access to the more detailed statistics and changing the tab you would have the splits (autolaps or laps created manually) or segments that you have marked.

Activity Summary, Garmin Connect

You can click on any graph if you want to enlarge it to analyze the details more slowly, and also compare it with any other of the values obtained (in this case I examine the vertical oscillation graph along with rhythm and cadence).

Garmin Connect Extended Graphics

There are many other sections, as you can see in the image of the breakdown menu: reports, segments, personal records, etc. I will not cover them all because it would be quite extensive and really the information you will consult most often is that corresponding to each activity, and it is not a question of making this test even longer than it already is.


There's no doubt about it. The Garmin Fenix 2 is a great watch, in every way. Not only is it big in size, but also in functionality and in the amount of things it will be able to do. After about six weeks, where the Fenix 2 and I have shared many hours, you can be sure that I have finished impressed. From its ability to help you navigate in the mountains, to Garmin's most advanced racing features, and even making you think it might be the perfect watch for a triathlete.

But not everything is perfect. The screen could be better in terms of readability and, above all, resolution. This is something that when we use data pages with four elements or in interval training with smaller text, it shows. Compared to a Polar V800For example, you can see quite a difference (in favour of the Polar).

Not being able to use Bluetooth with ANT+ simultaneously makes a feature like LiveTrack virtually useless, as I can't think of anyone who can do without all the pulse data when recording an activity, in favor of sending the live training. These are things that we are sure to see improved in future editions of this tremendous watch. Worth the wait? Hard to decide. If you need a training partner, I don't think you should wait. This device will satisfy the 90% of its users. in any of its many uses.

Is this the watch you've been looking for? If you're willing to spend this kind of money, I find it hard not to advise anyone. I can't see any reason why I can say "no, don't buy it". There's probably no one in the world who can take advantage of the 100% watch and who will take advantage of all its features. Although who knows, maybe there are triathletes who parachute, ski, climb and have a habit of measuring large areas while hunting and fishing. But with the 50% you'll be more than satisfied with everything it has to offer.

If you only want it for road running and you are not going to use navigation functions it is probably too much and it will be the only time you can say that this watch is not for you. But if you are someone who practices a lot of sports or who likes the world of trail running do not hesitate, if you choose the Fenix 2 you will not be wrong.

  1. Eduardo, thank you so much for the test. I've already put it on the list for the wise men. I was in doubt but you've made it clear.

    I wish there were more pages like yours.

    Still the same!

      1. Well this garmin would be configurable for use in spinning class ?

        Thank you very much for the piece of evidence

        1. Sure, you can use any profile (indoor cycling, for example), but if the spinning bike doesn't have bluetooth sensors you won't have speed or distance data, just the heart rate (and calories consumed)

  2. Hi, Eduardo.
    What do you think about the quality of the gps? Many have returned their unit because of bad data recording (you go through buildings, you make straight lines where there are curves etc...) all this is corrected if you put the clock to be more accurate and record every 1 second even if the battery lasts much less... Or is it really inferior to others in its category like the ambit3?
    I have been more than a month behind one (h not for the price), simply because of the quality of the gps. I am waiting for other watches like the Ambit3 that say that the quality of the GPS is much higher and more reliable... But Garmin has more possibilities of configuration and, that, in short...

    A salute!!

    1. Hi, Joaquin.

      I didn't see any big problems with the GPS. Just this weekend I went on a mountain tour with a Fenix 2 and a 620 and the results were very similar, even when I went through wooded areas. Checking the tracks they turned out to be similar too.

      I know there are a lot of complaints about the GPS chip, but it's something that I, in my unit, haven't had any problems with.

      When it comes to running and on my usual routes, which I have more than measured in terms of distance, I haven't found any mistakes either.


  3. Hello,

    Very good review. Congratulations.

    I come from Phoenix 1 and its headaches. I've had to change up to 4 units because of hangups, resets, malfunctions etc...

    From today I have a Phoenix 2, I tried it for a while this afternoon and it looks good... I hope it lasts

    Have you had any crashes or resets in your unit? Have you followed tracks and done trackback? With the fenix 1 following a track was a lottery, now I hang up, tomorrow I reset...

    I hope this is the one


    1. Thank you, Miguel.

      No, at no time have I ever had any hangups (other than being "thinking", for example when saving a long activity of three hours). I've done routes and tracks (the second heaviest), and I've also done trackback when I've been touched by a stream on the road that had passed by a big torrent and I had to turn around. I've never had any problem.

      I have read a lot of people who have suffered from these problems, I suppose it could be due to initial firmware versions (by the way, Garmin has just released version 4.1)


      1. since I have the 4.1 today began problems when I paused the session and wanted to restart or wanted to save, reboot after reboot, I had to do a reset and so far it works but I do not trust and before the 4.1 is 4.0 worked perfectly, you know if it is a thing of software and fix it in future updates or reset the clock will have been calibrated correctly, ... a greeting

  4. Excellent analysis and I hope the kings are good and bring it to me... Do you know if future firmware updates could solve the incompatibility between ant+ and connectivity conect?

    1. Hi Javi

      Thank you for your comment. If you've been good this year you'll surely get your award.

      It's not something that can be solved through upgrading, it's a matter of the ANT+/Bluetooth chip that Garmin had to choose when creating the watch. Unlike the 220 and 620, the Fenix 2's chip is unable to work with both types of connectivity at the same time.

  5. Enhorabuena por la prueba sin duda un diez por tu trabajo, detras de ella es evidente que hay muchas horas dedicadas al Garmin Fénix 2.
    After looking at which of them to acquire among suunto ambit 3, Garmin 920 , Polar , the balance has opted for the Garmin Phoenix 2., say that I am currently using Garmin edge 800.
    After two weeks with the nothing but I can say that is a piece of GPS, which meets the 200%, what I was looking for, a GPS watch with long battery life, multisport, the option of track, get the most out of running, as well as both mtb, as road, with lots of information and configurable to 100%, in addition to being able to use daily.
    What can I say about Garmin's technical service, as they are very friendly and when it comes to providing a solution they have no doubts about replacing you with a new unit.
    Por todo lo mencionado es por lo que me he decantado por este gran reloj GPS Garmin Fenix 2,
    Once again, congratulations on your fabulous analysis.

    1. Thank you very much Oscar for your message. It's nice to know that so many hours of work are so well valued.

      I hope you enjoy your Fenix 2 very much, but I'm sure you will.


      1. Thanks to you Eduardo, once again it is to thank people like you who do this kind of work selflessly. Spectacular contribution.

  6. Since I have the 4.1 today started the problems when I paused the session and wanted to restart or wanted to save, reboot after reboot, I had to do a reset and so far it works but I do not trust and before the 4.1 is 4.0 worked perfectly, you know if it is a thing of software and fix it in future updates or reset the clock has been calibrated correctly, ... a greeting and thanks for the web.

    1. Hi, David.

      Ahora mismo estoy usando un Fenix 2 para mis entrenamientos, y ya lo he actualizado a la última versión. De momento no he tenido ningún tipo de problema o cuelgue.

      It is true that I have seen the same problem in some watches of other users, who have complained about the same thing. If you do a hard reset it will surely help with this kind of problem.

  7. Hello!

    Great and deep analysis of the Garmin Fenix 2!! a question I have as a user of it. Do you know if you can delete activities from the clock? Do you have to go one by one? What if once deleted they are kept in the Garmin Connect?


    1. Hello Joseba

      You can delete activities from the clock. What is saved is the track data, the activity will remain in Connect.

      To make it faster, you can connect it to the computer, and all the files will appear there. Each activity is named by the date and time it was performed, you delete the file (or save it to the computer in case you want to repeat the route another time, if you want to use navigation) and thus free up space on the clock.

  8. What a piece of review, I wish every product I want to buy had one like this, IMPRESSIVE, thank you very much for the extensive and great work

      1. Thanks to you, now I only have to read the manual to try to control the trail/running part, the rest of the time I don't need 😀

  9. By the way, have you tried Phoenix 3 ? if so, what really useful differences does it have? is it worth buying it instead of the 2 ?

    1. I haven't had a chance yet. But as soon as it's available in some market I'll buy it, so you can have the proof available as soon as possible.

      In my opinion, I think the most important details will be more speed in moving through the menu, saving and loading activities, etc. And of course, Connect IQ, which although still very green I think will be an important platform in the not too distant future.

      But until I prove it, I can't give my verdict.

  10. Hi, Eduardo!

    I wanted to ask you if the same thing has happened to you that is happening to me in the Navigation mode of the clock.

    The thing is that when I put a track and start the navigation, the clock doesn't pick up the total of kilometers traveled, also with exaggerated differences, since in 15 km trips it tells me that I have only traveled 1 km. Do you know what could be due to this?

    Thank you.

    1. Sometimes it can happen that there are differences between real and marked distances. In fact it is normal, but what happens to you is not...

      The track you are following, how many waypoints does it have? If the file is too heavy what can happen is that the clock has a hard time moving it and the processor is only busy showing the navigation and not recording and tracking. Try to reduce the number of waypoints from BaseCamp, it will most likely help.

      If that doesn't solve it, try a full reset of the clock.

  11. Hi Eduardo, I've been using the Fenix 2 for about 6 months, and something that I don't like and that has happened frequently is that when I'm about to start a training session, the watch according to the steps, the first thing it does is detect the sensors, this makes it very fast, step by step it goes in to detect the location and this step many times sticks to me, so much so that I start the training, I record the track with the Nike Running app of my iphone and 2 or 3 km have passed and the watch keeps looking for the location. In view of this what I do is press the lower left button of the watch to skip this step, dispensing with the GPS. Sometimes what I've done is turn the watch off and turn it on again and start the steps again, but sometimes it works and sometimes it doesn't... Compared to the Forerunner 620, this is annoying. What do you advise? Why can this happen?

    Thank you very much for your response and as mentioned by many, many thanks for such a complete report on this watch, I have read it all and it has helped me to start managing some functionalities that I had not been doing.

    Greetings from Colombia.

    1. You have to wait to get a GPS signal before going for a run, as getting connected to satellites when you're on the move (especially if it's between buildings or more complicated coverage areas) is much more difficult.

      If you spend more than 3 minutes in the same place waiting for a GPS signal and there are no buildings or trees nearby, you might have a problem with the antenna or the GPS chip. If that were the case, you would have to make use of the warranty.

      1. Thank you very much, Eduardo.

        If there are buildings and trees where I regularly start my runs, I'll keep trying.

        Thank you very much.

  12. Thank you, Eduardo.

    If there are trees and buildings, I'll try it somewhere else. However, this was not the case with the Forerunner 620.

  13. Good morning,
    I have the Garmin Fenix 2 with the HRM-run but I can't see the Garmin Connect graphs for vertical oscillation, cadence and ground contact time.
    Do you know how I can make it to see them?
    If you want you can answer my email

    Thank you.

    1. In Garmin Connect nothing needs to be activated, it appears automatically when the clock is paired with an HRM-Run sensor. If this has happened after an update, reset the clock to its original values. To do this, with the clock off, press and hold the "Down" button and turn the clock on. When you get the message whether you want to clear all data, hit the select button.

  14. You can put in an activity the slope field?? I see it exists in the manual?? but in the clock I don't find it as an option?

    1. Yes, the slope is one of the data fields that are available. I can't tell you exactly where it is, as I don't have a Fenix 2 on hand right now, but I can confirm that you can select that field.

  15. Buenas Tardes tengo una pregunta porque cuando corro en vereda me marca intervalos de ascenso 100m sin yo haberlos programado.
    Y otra pregunta es sobre garmin connect sabes tu si se pueden registrar 2 pares de tennis para correr uno de trail y otros para asfalto no he podido hacerlo
    Thank you. Good day.

    1. Mario, I don't know what you mean about promotion intervals.

      As for the shoes, you can register as many as you want, but there is no possibility of automatically marking one for the "trail running" activity, you have to select it manually.

  16. Hola Eduardo: He intentado preparar una sesión de entrenameinto por tiempo en el fenix2 para natación pero es imposible, no lo consigo. Lo preparo en el training center, lo paso al reloj pero no lo reconoce. Sabes si es posible hacerlo de alguna forma?

  17. Good morning, Eduardo.
    I've been having fenix 2 for a month now and I'm really very happy. First of all, congratulations for the post, which is very clear and has helped me to understand how much the fènix is going to help me. I wanted to ask you if after an initial assessment test, the Vo2màx measurement and the heart rate in relation to the training zones are configured taking into account this more personal part. Or is it just an approximate assessment like the one you do when you haven't done the exact configuration yet?

    Thank you very much and congratulations again.

    1. No, the marked frequency zones and the VO2Max value are not related to each other.

      The FC zones are configured in a traditional way (the typical 220 minus age, etc). If you want to have the zones well configured, you will have to do it by means of an effort test, where you will be able to mark each one of the zones well.

      As far as VO2Max estimation is concerned, what it does is take data such as age, sex, height, weight, etc. and combine it with rhythms and pulses to, through an algorithm, compare it with data from other athletes and thus assign you an ESTIMATED VO2Max.

      Again, to be of real value, you will have to take a stress test.

  18. Morning,

    I would like your opinion on whether it is advisable to buy this watch from me or to wait and save for the fenix3.
    As far as I can see, the price difference is about 150 euros.
    On the other hand, is the garmin chest band of good quality and worth taking in a pack? I understand that in a pack it is always more economical.
    Thanks in advance and congratulations on the piece of work you do.

    A salute.

    1. The Fenix 3 outperforms the Fenix 2 in everything. In my opinion, for that price difference the Fenix 2 is not worth it.

      The HRM-Run pulse sensor is of good quality, besides having a specific accelerometer for the race dynamics functions that only has that sensor, so it is advisable to buy it in kit.

  19. Eduardo, a friend advised me to keep this watch above 220 or 620. What do you think?

    1. If your use is exclusively for road racing and you don't need any of the extra features of the Fenix 2, it's not worth it. You'll be paying for features that you won't be using.

  20. Perfect article, one thing, I've been testing the distance and speed 3D comparing it with the 620, on a slope of 3Km with a difference of 250m, and the truth is that the fenix 2 when I get to the top marks me about 25-30m more than the 620, but when I go down to the same starting point, the pulse meters begin to equal, so much so that once down I mark the same distance, have you noticed something of this?

    1. Note that GPS measurement is not accurate either, and that the 3D distance is a mere approximation and an aid to determine distances with a little more certainty, but focused on large routes and with important unevenness (i.e. in the order of 20-30 km and 2000 or 3000 meters of positive unevenness).

      As you can see, the function, as an approximation, works, but just as the distance figure measured by GPS cannot be considered a clear and exact value, even less so when we introduce other non-exact measurement variables (such as altitude in this case).

  21. Hi Eduardo, the Fenix 2 is at 199 I am a runner, between this and the 620, which one would you stay with? I know that the Fenix has more functions but if I have the same as in the 620, I save and also I have much better battery.

  22. Hello Eduardo, great job if Mr. luck we have some people like you, without going further myself acquired this cucumber clock because an acquaintance changed it and I left it very good price, I came from the 220 forerunner imagine the difference and after touching a little thought "much clock for little runner" and the truth is that I did not know where to put your hand and looking for the network found your tutorial and the truth is that I saved the skin.
    And once put I take the opportunity to make a consultation, because when I pass an activity such as running to garmin connect I do not pass it as a race and puts it in others ... thanks

    1. Thank you.

      Make sure that the sports profile on the watch is selected as a race. Not mountain running, or walking, or any other variant.

      1. Today I tried it again and I put it in running and when it passes to me to garmin connect via bluethoot I load it in others I have already tried several things and there is no way

          1. The complete reset you do from reset? and once inside reset there are three options, history,waypoints and all settings, which reset all settings? thanks

          2. The easiest way to reset is, with the clock off, to hold down the scroll down button and then turn the clock on (while still pressing the button). When the message "Clear all user settings? appears, say yes.

          3. and then you do a total reset and have to reconfigure everything from 0 as if it came from the factory?

  23. Eduardo,

    Congratulations on the great test, and thank you! Eduardo I bought the Fenix-2 and I wanted to ask you a very specific question: is it possible that the Fenix-2 is the one that counts the steps I take in my day-to-day life? I know that there are dozens of applications on the phone to carry out this function, but I don't usually carry the terminal during the day, but the clock does!

    Thank you very much for your answer. Greetings!

    1. No, the Fenix 2 does not have an activity monitor, which is what allows you to count the steps on a daily basis.

  24. Eduardo, I would like to tell you if when I am on the bike or spinning, if the clock on the screen appears in the area you are training or if it could be put, thanks

    For example 4.56
    If he can appear in the area we trained in the same way he appears in the phoenix 3

  25. Hi, thanks for the detailed review, but I have a question, maybe you can help me, it happens that when I connect to garmin connect and want to transfer a training plan, it asks me to do it through garmin express, but it recognizes it but says that it is not compatible and asks me to do it through garmin map, when I install it asks me for a code, which I don't have. The clock is updated manually to firm 4.5. Could you help me to transfer the training information correctly?

    Thank you!

    1. Synchronisation must be done automatically. The workout is created in Garmin Connect and the Fenix 2 is selected as the device to receive it, and you must get it on the next synchronisation done from the clock.

      1. Hi Eduardo, thanks for responding, the problem I have is that garmin express tells me that it is not compatible with the device. I can only synchronize from the phone via bluetooth, but I can't access the total options from there.

  26. Hi, everybody, I just bought a FENIX 2...since yesterday I have put it to make the first charge, I have taken it out and tried to turn it on and without results, it does not turn on, I put the USB charger and it works, I leave it charging, I take the charger off and nothing does not charge me...someone has had this problem? thanks,,, I am very worried

    1. Leave the watch connected to the charger for a few hours, the battery is probably too low (too long stored).

      If it doesn't start, you'll have to ask for a replacement

      1. Hola Eduardo, gracias por tu respuesta. de inicio lo dejé 24 Hs. conectado a la red eléctrica. Anoche, lo deje conectado (sin el transformador) directo al puerto USB de la Notebook y se cargó completamente, esta mañana, luego de 7 hs de carga. Funciona perfecto, aun no se que pasa con la conexión a la red eléctrica via el transformador. Por otro lado probe el transformador con un cable de carga de otro reloj GARMIN y funciona perfecto.

  27. Ok. I was wondering why I read some comments in which some users have complained that they have been wetting themselves when using it underwater. In my practical case snorkeling. And I would not like water to get inside my phoenix 2.

    Greetings and congratulations on such a thorough analysis.

  28. Friend!!! NOTE you are a connoisseur about fenix 2 and I have a problem 🙁 I have my device 4 months ago and I don't know if it is a software or battery problem but it is working at 100% and when I disconnect it it turns off without warning, it only works connected to the charger in any other way.... please help me 🙁
    or do you know how to validate garmin's guarantee for amazon ???

          1. Yes, in theory both with Basecamp and by connecting the clock and accessing the memory you could do it.

  29. Thank you Eduardo for this great contribution and above all for the dedication of countless questions that we usually ask you. I have a doubt about it and I haven't been able to find it anywhere, when I load a mountain track I have the possibility to visualize a total altitude map of the route as for example the barometer shows?
    That is to say, I go out a lot with mtb and when you are broken it helps a lot to know in which point of the route you are and what unevenness you have left or are waiting for.
    Thank you in advance

    1. No, the Fenix 2 does not have that screen. It has just been incorporated into the Fenix 3, with the Ambit3 Vertical being the first watch to have it, but the Fenix 2 will not receive it.

  30. Hello I have a question I would like to buy a watch and I am between the fenix2 and forerunner 230 which would recommend me? I await your response greetings and very good your analysis

    1. They are two very different watches with very different uses... It's up to you to decide which one suits you best.

      1. I understand thank you for your attention, I am an average runner not swimming and I run bicycle sporadically! The differences you tell me are? In my country I can not ski! I see that the 230 is not a watch so daily I look for something that fits the runner lifestyle but also can be used comfortably daily

  31. Eduardo, I had a problem with my garmin fenix 2. Yesterday I finished running, I saved the activity, and I went to "details" to see all the data. I didn't want to press the button to turn it off, and when I didn't want to do it, I pressed the "back" button, to go back to details... on the screen I saw a "loading", the clock went off and it didn't turn on again. what could have happened? it's worth mentioning that it was drizzling while I was running, but I didn't press the buttons...

  32. Hello again Eduardo, could you tell me if it's possible to load a track to follow it but to do it upside down? I recorded a route but I'd like to do it again from the end to the beginning. Thanks!

    1. No, if I remember correctly, it doesn't. You can start halfway through, but not the other way around.

  33. I can't get a pool length of less than 20 meters (mine is 15). Is this a limitation of the device? Can it be solved in any way? It doesn't say anything about it in the manual.

    Thank you very much!

    1. In more modern models, the minimum distance has been lowered to 17 meters, but it is still too short.

  34. Hi, Eduardo,

    first of all congratulate you on the article, which although it has been a long time, it is still very useful for those of us who have this gps. thank you.

    I have a totally updated fenix 2 and I just bought the Garmin HRM-Run (the one with the white running doll) to measure the race dynamics. For me, this is crucial data, so I spent the 100 bucks to buy it. In the fenix I have configured a screen to see the dynamics. In the race, I see the cadence, oscillation, contact time... everything perfect, but in Garmin Connect (both in mobile and web) I don't see graphs with this data or relevant information.

    I need to update something or configure something to be able to use these graphs? I don't want to think that I have spent money in something that is not useful at all (my previous Geonaute band of Decathlon connects through Ant+ and gave me the heart rate, a fundamental data for me and with which I was more than enough if I can't measure the rest of the data).

    I look forward to your comments, thank you and congratulations again!

    1. You shouldn't have to make any configuration changes, the data should be recording in the FIT file and, after synchronizing the activity, appear in Garmin Connect. And if the data appears on screen, the sensor is correct.

      If after two or three days of training it does not appear in Connect, try resetting the values on the clock.

      1. Thank you very much Eduardo, everything has been solved with a reset of the clock; I already see all the graphs. The only one that doesn't come (I understand that because of the fenix 2) is the activity time in each cardiac frequency zone, something that would be very useful to me but that I understand I can't have with this device.
        Thanks again!

  35. Greetings Eduardo, Super good review of the GarminFexin2. Very instructive. Now, I would like to take the opportunity to consult with you regarding the inclusion of the heart rate widget?


    Ronn Ariaas.

    1. The Fenix 2 is not compatible with any type of widget, and in order to have it, you would need the optical pulse sensor

  36. Hola Eduardo, saludos desde Ecuador, gracias por tu valioso aporte, por favor ayúdame con lo siguiente, a mi garmin FENIX 2, parece que le entra agua, ya que se le humedece la pantalla y y tiene una condensación que no permite visualizar de manera correcta la pantalla, a penas lo tengo 4 meses, ya me da temor realizar los entrenos con el reloj puesto en la piscina.
