Garmin Forerunner 920XT detailed review

Introduction

It’s been a long time since my last post on this site. In the meantime a lot happens in my life. Also with my running equipment. In the meantime I was the owner of following watches: Fenix 3, Ambit3 Peak, Polar V800, TomTom Multi Sport. But for a year I’ve ended up with 920XT. Did I liked it? Let’s find out!

History

On 1st October 2014 Garmin introduced the 920XT. New triathlon watch that was a successor of the 910xt. The watch, besides being a multi sport GPS device, was also an activity tracker and introduced the idea of downloadable apps called Connect IQ with color screen. The battery life was a impressive 24 hours in 1 second sampling mode. Bluetooth and WiFi connectivity. On paper it was a perfect device in my opinion. So what was wrong with it? Well, the design, if you ask me. It wasn’t a watch that I’ve fell in love from the first the first sight. But when I’ve finally decided to buy it and start using it, it appeared to be the best GPS device I’ve been using ever since!

About the watch

The watch is quite bulky but impressively light. About 61g. The design reminds me of the Casio watches from early 90′. On the beginning I thought it is ugly as hell. But in real life on the wrist it looks ok. Not too classy to wear with a suit but if your work doesn’t require it then it is perfectly capable to wear as a daily watch. Especially if you are a geek like me:).

Battery life

The declared battery life is as follows:

  • up to 40 hours in UltraTrac mode
  • up to 24 hours in training mode
  • up to 4 months in watch mode

I’ve noticed that the watch for my usage lasts about a week with following conditions:

  • 24/7 activity tracker
  • Bluetooth/WIFI connectivity

6hours of GPS activities (1s recording, without Glonass).

Which for me is perfectly fine. I tend to charge the watch every weekend. Full charge takes about 2 hours.

I have done a balcony test of the watch with following settings:

  • 1 sec GPS recording,
  • none backlight,
  • no ANT+ devices,
  • activity tracker enabled,
  • Bluetooth Enabled but no notifications,
  • run activity.

I left the watch fo whole a day on my balcony and wait until it’s battery is dead. The result is:

20161011_085019

So 16:00:55 and 8.44 km were recorded. Looks like it is almost 8 hours short from the promised 24 hours. The reason could be the mentioned 1 sec recording instead of smart + other options that are enabled. Plus the watch is almost 2 years old (I have it 1 year but actually it was used before for 1 year also since it’s second hand) so the battery could degrade already.

If there will be interest I will do a second, battery save test, with all additional settings disabled + Smart recording.

But to be honest I’m not sure if the 24 hours mentioned by Garmin is reachable. That issue is also mentioned many times on the official Garmin forum. It’s not a crucial thing for me but for some ultra runners could be a deal breaker.

What’s important. The watch cannot be used while charging. Once charger connected the activity stopped and the charging screen is shown. Afterwards we cannot continue the activity.

Running

20161008_140445

In the running mode the watch allows us to configure 4 data screens. Each can contains up to 4 data fields. Additionally we can add the following screens:

  • Map – shows the breadcrumb of the track
  • Virtual Partner – allows to configure the pace of the partner and shows graphically if we are behind or ahead of the partner, time ahead/behind and our average pace
  • Running Dynamics 1
  • Running Dynamics 2 (more about running dynamics in another post)
  • Clock

Additionally for running we have the following options:

  • Auto laps – allows to automatically take lap by distance (configurable).
  • Auto pause – stops the activity if not moving (personally I don’t use it for running, only biking).
  • Auto scroll – scrolls the data fields (available 3 speeds: slow, medium and fast).
  • Metronome – allows to set beats per minute, alert frequency (every beat, every third, every fourth beat, every sixth beat) and alert type (tone, vibration, tone and vibration).
  • GPS – enable/disable.
  • Power Save Timeout – if we leave the watch on the training screen, the watch will end the activity after a minute, with this setting enabled this time will be extended to 5 minutes. Very useful before a start in an event when we wait for the start.
  • Alerts – by heart rate, distance, pace, time, distance, calories, custom.

I often run my long runs with the auto lap set to 5km. Shorter runs with 1km. It’s important that after starting the activity this can be edited. It happens to me very often so I thought it was important to mention (newer watches like 735XT doesn’t allows this).

I’ve been running with this watch for over a year. During this year I’ve done a full half marathon and marathon training. One of the biggest advantages of Garmin Forerunner series are it’s training capabilities.

On the watch we can create a basic interval training. We can add warm up, cool down phase. Set the interval (by distance or time), rest (also by distance or time) and number of repetitions.

Simple interval training

More advanced trainings can be created in the Garmin Connect and then synchronized back to the watch. In Garmin Connect we can also add the created training to the calendar and then send back to the watch. Such trainings are then available in the watch from the Training Calendar section. I’ve been using this numerous times and was fast and comfortable. My routine during training for the half marathon and marathon with this watch was as follows:

  • In the weekend, after long run create all required trainings in Garmin Connect.
  • Add the trainings to the training calendar (also Garmin Connect).
  • Send the Calendar to the watch (Garmin Connect).
  • In the watch sync over WiFi the changes (works very fast!).

And that’s it. Then during the week I’ve was only using the calendar in the watch.

Training step summary

20161008_141108

Training Screen

During the training the watch shows additional data screen with 3 data fields. The big field shows always the current training step with time/distance until end. The lower 2 shows the step requirements (required pace, heart rate range) and current lap (step) distance. Watch gives different alerts if we are below the required range or below. Before next step the watch beeps 5 times and then shows the summary of next step. Very straightforward.

What’s important when training with the pace as indicator. The current step pace is always calculated from the step average. It’s different than e.g. in the Polar V800 where it’s always the current pace. Personally I like better the way Garmin way with average pace.

It is not possible to create advanced workout on mobile app (or watch). It has to be created in the web interface and then can be synced. We can however, on mobile, select an existing workout and trigger the sync to the watch.

I always run with connected foot pod. That’s because I always use the instant pace data field when I run. With GPS the value is always calculated over time and somehow smoothed. Thankfully 920XT allows to show the instant pace from foot pod while using GPS. The foot pod can be automatically calibrated with the GPS. It’s a perfect solution because in the 310XT I have to calibrate it pretty often manually (either by known distance or trigger the GPS calibration from options). Here it happens automatically. The only disadvantage of the instant pace in general is that by default it’s rounded to 5. So we cannot see if we run 5:42 but always 5:40 etc. But that can be fixed with the data fields available on ConntectIQ.

In order to set the foot pod as speed source we have to go to Settings -> Sensors and Accesories -> Select foot pod -> Use as Speed Source -> Select: Always. That’s it.

Use foot pod as speed source

20161008_144421

Calibration factor

On treadmill the watch can calculate the speed and distance with the build in accelerometer but I didn’t found it to be accurate. The speed and distance was off the one selected on treadmill by 10-20%. With calibrated foot pod the speed and distance were very accurate (off about 1-2%). But of course who knows if the treadmill were correctly calibrated. But the difference is noticeable.

Additionally when running we can create a route in Garmin Connect or use a route from our previous activity and run with a map. I rarely used this feature while running (once lost it was faster for me to just use Google Maps on a phone). Very useful though it the Back to start functionality. I was using it numerous times when running in new places or doing trail runs (sadly my orientation is not so good).

I also want to mention that the watch have the barometric altimeter. So the elevation profile generated after the run or bike activity (in fact every GPS activity) is very accurate. I haven’t got any problem with it and the data is quite accurate even without any calibration (+-10meters).

I haven’t mentioned about the heart rate strap and the accuracy. That’s because it was working fine and I haven’t got any problems with it. The heart rate strap bundled with 920XT is the HRM-RUN and it’s working just fine – as expected. The only important thing about it is that if we want to have the mentioned earlier Running Dynamics 1 and 2 data fields we have to use this particular strap. The older ones doesn’t have this functionality. I will write a separate post about running dynamics soon.

Here are some of my running activities done with the 920XT:

Biking

20161008_140524

Just recently I have started to ride a road bike. The big plan is to prepare for a triathlon. I bought an used road bike and started my journey on the roads with 920XT (which was a big help).

The bike functionality in terms of data screens are the same as for running (without running dynamics 1 and 2). We also hate the possibility to configure alerts (with speed alert instead of pace and additionally power alert). The only thing that’s different is the lack of metronome.

I was using the bike with the addition of the speed and cadence sensor (GSC10) and the official bike mount.

bike-mount-garmin

gsc10

GSC10- speed and cadence sensor

What’s important – the GSC10 calibrates the speed automatically based on the GPS which is very comfortable.

As I said road bike was a new thing for me. Route navigation from 920XT helped me significantly. I’ve often took a route from a friend on Strava (or from the ones available on Endomondo), imported it to Garmin Connect and synced back to the watch. Route navigation works tremendously well and allows to start the route navigation in any place (not only on the start of the route like on Polar V800). If off the route the watch shows the distance off. The map can be zoomed in and out.

Route elevation profile

The routes areworking fine, speed, distance, heart rate were recorded correctly. I don’t know what more to say since everything was working perfectly fine for an amateur usage. Also I’m not an experienced biker and have no other watch to compare.

Some of my bike rides:

We can also use the watch for indoor training. Sadly I haven’t tested this since I don’t have a indoor trainer yet.

It is also possible to create training plans for biking (both for indoor and outdoor mode).

Swimming

920XT can be used for 2 types of swim trainings:

  • Pool Swim.
  • Open Water Swim.

Pool Swim

20161008_140508

In the pool swim mode the watch uses the accelerometer to estimate the distance. Every time we reach the pool end and push from the wall the watch detects it and add to the distance the pool length. Straight and simple. Works very well assuming that:

  • We don’t stop in the middle – could happen e.g. when there are lot of peoples on the lane.
  • We don’t change the technique in the middle of pool length.

From my tests I could honestly say that pool swim on 920XT works very well. Generally for a 1km distance the error in my case is max 1 pool (less or more). The same was in the case of Polar V800. Worst results I have with TomTom Multi Sport where the error was always about 5-10 pool lengths more than the actual number.

In terms of data screens it’s the same number as for the other sports. Additionally we can enable the Drill Log. It allows us to mark the drills interval with the back button. The watch shows also the SWOLF metric.

Additional configuration settings:

  • Pool size: predefined are 25 meters, 50 meters, 25 yards, 33 1/3 meters, 33 1/3 yards and custom (from 17-150 meters/yards)
  • Stroke Detection – detects the style, works ok but since my technique is not perfect it works about 80% of the time (on Polar V800 the accuracy was almost perfect)
  • Alerts (time, distance, calories)

In order to record the heart rate underwater we need the HRM-SWIM strap. Works very well and don’t fell off the body when pushing off the pool wall but costs about $100. What’s also important – it will not show you the heart rate during the activity. The watch downloads the heart rate data after swim. Was ok for me but it’s worth mentioning. The reason for that is because ANT+ transmission doesn’t work underwater. On Polar V800 the analog signal can be transmitted underwater so the heart rate works out the box with the H7 heart rate strap without the need to buy additional accessory. But on the other hand the H7 strap was falling off every 4th push off the wall. The HRM-SWIM was not falling down so often (but it did, at least in my case). So it’s up to You to decide what’s better.

hrm-swim

HRM-SWIM heart rate strap

Here are some of my pool activities:

What’s also important. Since firmware version 7.10 it is also possible to create training sessions for pool swimming. The sessions can be created in Garmin Connect and synchronized back to the watch. Same like for running and biking.

Open Water Swim

20161008_140524

In this mode the watch uses the GPS and some algorithms to calculate the distance when swimming. The problem is that every time the hand go under water the GPS signal is lost. So the distance will always be somehow estimated and depends of the algorithms quality.

I haven’t done any training in this mode so I cannot say much about it and how it’s compare to other watches. I know though that once I start seriously the triathlon training I will go back to this section and update it.

When it comes to activity settings we have the same options as for others activities (data screens, alerts, laps).

GPS Accuracy

From my experience I know that newer Garmin models, although better in almost every way than the old ones, have got worse GPS accuracy than the good old models (like 305 and 310XT). The tests made by Fellrnr are proving that to be true. I was scared that the accuracy of 920XT will be horrible but that’s not true. I have got previously the Fenix 3 and anything other than running on straight line without tree cover or buildings was problematic (it was cutting corners like crazy and the distance was always too short, for a $100 watch I could swallow this, but not with the price of almost $500- topic for a different story).

920XT is perfectly fine for running in the city and under tree cover. Only once I have a case when in direct comparison with Ambit 3 Peak for a trail run the distance on 920XT was about 600 meters shorter (on 30km distance). Ambit 3 Peak have, according to Fellrnr, much better GPS receiver so I assume that it’s the one I should compare to. But I had only 2 watches so who knows. On my recent marathon the measured distance was 42400m so in my opinion very good. The 310XT measured 42350m (the same route 2 years earlier).

Here are some of my runs:

Type of run 920XT distance Other watch 1 distance Other watch 2 distance
Village, almost no cover 30,01km

Ambit 3 Peak

30,01km

City + trail run (the one that was problematic) 29,42km

Ambit 3 Peak

Forerunner 220

21,30km

Village + trail 10,06km

Tom Tom Multi Sport

10,00km

Forerunner 220

10,01km

As we see only once the readings from 2 watches were oddly off each other. Other than that there are almost always pretty close.

The quality of tracks is good. The ones generated by Ambit3 Peak are in my opinion better but just slightly.

At the end GPS accuracy of 920XT is perfectly acceptable. There are watches with better GPS chips but for an amateur like me it’s fine. For more scientific tests please visit the mentioned earlier Fellrnr website.

What is also important – I’ve never had any issues with lost GPS signal or inability to retrieve the signal after running under a bridge.

The time the watch needs to get the GPS signal before the run is usually max 10 seconds. It happen to me only few times when the time to receive the GPS signal was between 1-2 minutes. It was after update and when I was on vacation (I moved about 2000km from my last run). Other than that it’s really fast.

 

Connect IQ

screenshot_20161008-144146

Connect IQ adds the ability to install additional apps on the watch. There are 4 types of items that can be installed on the watch:

  • Applications
  • Data fields
  • Watch Faces
  • Widgets

Applications are, as the name could indicate, a stand alone app that we can run on the watch. At the same time only one app could be running. There are available on the activities in the menu Apps. Sample apps that I use are: Stopwatch (yes, 920XT need an app for that, it’s not build in), dwMaps (Google Maps), Find My Car, GPS Position.

20161008_144837

Gym application

Data fields are extending the build in sport types. Sample data fields available in the Connect IQ store are: elevation change, graphical heart rate, visual pace chart, 1second pace (to overcome the rounded pace). For a activity type we can use simultaneously only 2 Connect IQ data fields. I don’t know why it’s limited but that’s the fact.

Watch faces replaces the watch face. There are numerous available in the Connect IQ store. I still use the default one and the reason is simple – battery life. I noticed that the more advanced watch faces are draining the battery so I use the default one.

Widgets are small apps that are available when pressing up/down when the watch is locked. Sample widgets that I use are: weather, compass, altitude, sun calculator.

Connect IQ allows to extend the watch functionality in numerous ways and was a great move from Garmin. I use them all the time.

Links to Connect IQ items available for 920XT.

Installing app is very easy. Just select the app (mobile or web), hit Download and sync to the watch. Depending what type of app was installed it will be available in the mentioned place.

Connect IQ is certainly becoming an mature and important feature of Garmin ecosystem. The apps have much greater abilities than for instance year ago (like ability to be configurable or direct access to ANT+ accessories, support on not only watches but also bike devices – selected Edge’s). I have the feeling that if Garmin would give a good way to monetize developers effort it will  be a big hit! Devs are doing it already but with some workarounds like buying the code direct and then entering in the app. It works but is not user friendly. Didn’t App Store and Google Play thought us something?

Activity tracker

920XT can be used as an activity tracker (if of course it’s size is not a problem for you). It measures steps and track sleep. The steps count required every day is calculated automatically based on history. If you move a lot the number will be higher etc. Additionally you can enable the move alert which will tell you to move after the watch detects 1 hour of inactivity.

20161008_144327

Activity tracker widget

In the night the watch tracks the sleep. It detects automatically when we fall asleep and wake up (based on the wrist movement).

What about the accuracy? When it comes to step counting it’s very good. The only situation that when it is failing is driving a car. The watch count steps when I turn the steering wheel. For short rides in the city witch many turns the watch could count up to 500 additional steps this way. And that’s the only problem I’ve noticed regarding the steps tracking.

For sleep tracking it depends. Sometimes I just lay in bed for a long time and watch TV in one position and then fell asleep (damn Netflix!). Very often this time time is counted as a sleep. The same in the morning. For me it’s an estimate value and I wouldn’t rely on it. Either way I think it’s impossible to really detect sleep without the optical HR (my wife have the Fitbit Surge – there the sleep detection works much better).

The steps and sleep data is automatically synchronized into Garmin Connect and can be viewed analyzed there.

screenshot_20161008-143842 screenshot_20161008-144042

920XT doesn’t support the Move IQ. Move IQ is the technique garmin uses to detect an activity and automatically saves it (a rip of Fitbit’s SmartTrack). Cheap Garmin Vivosmart have it and a high end watch doesn’t.

I think  the activity tracker is a nice addition to the watch but in my opinion it’s not it core functionality. Activity tracker on 920XT is not perfect but tbh. i didn’t find a perfect one yet (but Fitbit Surge is really close).

What’s missing, bugs

I’ve been using the watch for over a year. It was a long time to test it and draw some conclusions, notice what’s missing etc.

Bugs that I’ve noticed:

  • The routes could not be synced over WiFi. I always create trainings, routes etc on my pc and then trigger the WiFi sync from the watch. One thing that is not syncing at all are routes. They sync over Bluetooth and cable. But not WiFi.
  • During my 1 year of experience with 920XT hangs only once. In the middle of 2 hours bike ride. After reset the I have lost the track. I cleared the saved activities and it didn’t happen ever since. So I think the reason was the full memory of the device (it contains activities from 7 months). So make sure to clear the activities before important starts/trainings.
  • The strap fell apart after a year of usage. I replaced it for about $20. Maybe it was my fault or it’s quality was bad. There is a small thread on Garmin Forum with peoples with the same problem (but thankfully not so many).

What’s missing in my opinion:

  • Music control! I often run with my smartphone and Spotify. On Fenix 3 I didn’t have to take out phone in order to change the song. It was available from a widget on the watch. Here it’s sadly impossible since this functionality is missing.
  • Move IQ. Cheap Garmin activity trackers have it, this one not.
  • Floors counting. In my opinion every great activity tracker supposed to have this (especially when the watch already has the barometric altimeter)!
  • Lactate threshold test. It’s available in newer running watches like 630, 735XT. Was also introduced to Fenix 3 but somehow Garmin skipped the 920XT.
  • I would love to have the 920XT with optical heart rate sensor (just like Fenix 3 HR). Sadly Garmin never decided to release such version.
  • Possibility to configure the activity data fields globally in Garmin Connect. I really liked this on Polar V800 – there all of this could be made in Polar Flow and the changes persists the watch hard reset. Here after hard reset everything needs to be configured from scratch.
  • Audio notifications in headphones (through smartphone) – again, an option that was pushed to Fenix 3 but 920XT was skipped

Other nice features

On the end I want to mention about some other features or the watch:

  • VO2 MAX estimation- what’s VO2 MAX you can read here. In short it’s an indicator of your performance (bike and running). In order to estimate the running VO2 MAX you need a heart rate strap (any, not only the HRM-RUN). To estimate it for bike you need also any heart rate strap and power meter. My VO2 MAX estimation at this moment is 46. My best was 50. I don’t know if those values are correct. But I can definitely say that when it was 50 I have much more power in legs and was running much faster. So based on that it is a valuable feature. What’s interesting- for a month I was running both with 920XT and Suunto Ambit3 Peak. On both watches the VO2 MAX was on the same level – 46. In order to estimate VO2 MAX for biking, the power meter and heart rate strap is needed.

  • Recovery advisor. The watch tells you automatically, based on the effort and training duration, how long you should rest in order to recover. I was trying to follow those suggestions and this year I haven’t got any major injury. Of course the most important for me was always to listen to my body but either way it was a nice help.

    Recovery

    Recovery Advisor

  • Recovery check. After few minutes of a run the watch tells you, based on your heart rate, pace and recovery advisor if you have recovered completely from the last training or not. And tbh. when the watch tells me  that my recovery status is poor I have felt that way. So it’s definitely working fine for me.
  • Live tracking – just start the session from the mobile phone and share the link with your live position on e.g. Facebookscreenshot_20161008-144025
  • Smart notifications- ability to show the notifications from selected apps, notify when somebody calls or sends us a message. Can be enabled/disabled.smartphone-notifications-to-the-920xt

Summary

By far for me that’s the best watch I’ve been using ever since (and I have experience with e.g. Fenix 3, Polar V800, Ambit3 Peak so the absolute top). But you have to swallow it’s bulky design. There are few small bugs and things that are missing but it’s nothing that could disqualify it. With the addition of the Garmin Connect ecosystem I am sure that it is a perfect training companion for most of runners, bikers, swimmers and triathletes.

Personally I love it and wear it all the time.

And just something about 920XT design. My wife (she has a very good taste) loved Fenix 3 and hated Polar V800 design. She recently told me that on the beginning she thought 920XT it ugly as hell. But after a while she started to actually like it on my wrist. So I think it’s a matter of time before peoples get used to 920XT look.

PS Just to be perfectly clear. I didn’t received the watch from Garmin or any other store. I bought it myself. It’s not a sponsored review or any other marketing bulls&%t. I just liked 920XT and it’s my hones opinion.

  • keep up the good work!
    if you compare to the 735xt then there are a few peripheral things missing for tri. running power done properly was a big omission but stryd and garmin have now sorted that. the 920 will always lack ciq2.x compatibility.

    what did y ou mean by “only disadvantage of the instant pace in general is that by default it’s rounded to 5. So we cannot see if we run 5:42 but always 5:40”

    • Hi, thanks for the comment! I’m a big fan of your site.

      I will do a review of the 735xt in upcoming weeks once I receive it and do some proper testing. Sadly without power meter in general since biking is not yet my main focus. Especially during late autumn and winter season.

      In the sentence about the pace I mean that with build in instant pace data field it’s not possible to see the exact pace, only always multiplication of 5. So it’s rounded. I hope I explained it correctly.

  • Pingback: My thoughts on Garmin Fenix 3 | Geek on track

  • Hi. First trail run with my new garmin forerunner 920xt, under deep tree cover, and the result are not good when compared with gps accuracy of the suunto ambit 3 and A-rival spoq s100. The results:
    A-rival spoq s100 = 12.2km
    Suunto ambit 3 run = 11.73
    Garmin 920xt = 11.58

    I know that garmin 920xt is a thriatlum dedicated sports watch, but are clear that SIFSTAR gps of suunto and A-rival are the best.
    Its incredible the gps accuracy of the A-rival, a 100€ gps sports watch.

    • Hi! Can you compare the tracks on http://www.mygpsfiles.com/app/ and share the results?

      I don’t know the performance of the A-rival but I certainly know that the Ambit3 Run has an excellent GPS accuracy. So why do you think the A-rival is so great if the difference between the Ambit was almost half km? It looks that the A-rival is overestimating the distance (big difference) and the 920XT is underestimating the distance (a bit). Keeping in mind that the Ambit3 has got the best possible accuracy of those 3 watches.

  • Hi. This is the track comparation of the 3 watchs:

    I don´t understand why when i export the tracks for gpx format the distances are bigger than the watchs results?

    It is possible observe that at the end of the course the a-rival has a trigger behavior of suunto and 920xt. However, and in general is possible conclude that 920xt shows a more divergent course when compared to suunto and a-rival.
    What is your opinion? Best regards.

    • Hi! The mygpsfiles makes some distance adjustments by their own algorithm. That’s the reason it shows different distance. I agree that of those 2 watches the 920XT has the most bumpy track. Personally I would do some more tests and then decide if the accuracy is on acceptable level. And of course correlate this with other features that Garmin provides. Personally I’ve decided to stay with Garmin with slightly worse accuracy but much more features and best ecosystem (here a totally subjective opinion). But again, I don’t do so often runs under heavy tree cover and didn’t noticed such drastic differences.

      But certainly I will do next week some trail runs with V800 (I just recently bought one specially to do such comparisons) and 920XT to compare the results. Also the A-Rival lands on my buy&review list in the near future:).

      • Thanks for the replay! In enviroments with heavy tree cover i already expected this result from 920xt. For me in this conditions, the best watch are suunto ambit 3 run/sport or peak , polar v800 and A-rival spoq s-100.
        Most of my runs are also done on city, but I always have a strange feeling about spending 330€ on a watch with this performance in terms of GPS.
        When you compare the polar v800 and 920xt, post the results, however no doubts about what we expect. V800 Will be more accurate and the 920xt will have less km in total of race.
        Good tests! Best regards.

  • This is the correct track comparation of this morning activity among the 3 watchs.

  • Hi again! Yesterday my first run in the city with garmin 920xt. The results obtained were very close when compared with suunto ambit 3. The difference was only 10m less in the ambit3.

    In the next few days I will do more tests in the city and if the results are maintained, the 920xt is an added value because of your great features in structured workouts. Best regards!
