Garmin Enduro, the Garmin ultra trail watch is now official


The imminent release of two new Garmin models should not be any breaking news. We are talking about Garmin, who until now had us accustomed to years with more than 20 new model announcements from different segments, a presentation cadence that was truncated in 2020 for obvious reasons.

However, Garmin's machinery began operating last week with the launch of the Garmin Lily, a small smartwatch focused on the female audience. But there are still pending some announcements that should have arrived last year and we still don't know anything about. These are the releases I thought Garmin was going to make last year (news I announced to you in March 2020):

All that has already been announced, but a few things were still pending.

  • Garmin Enduro — At first I thought it would be a specific Edge for mountain biking, but it turned out to be a watch for ultradistance
  • Garmin Forerunner 955 LTE and 955 — LTE version as the most important thing to highlight
  • Garmin Vector Air — Opposing forces cycling power meter (power estimation by speed and wind) and, combined with a direct measurement power meter, real-time CdA analysis. The presentation may have been delayed to better refine the algorithm.
  • Garmin Forerunner 655 — I'm not very clear that the project is going forward, I don't know if there is a gap in the range to introduce this model

Well, it's the first two that I want to talk you about today.

Garmin Enduro

--- February 13th update

We have images of the Garmin Enduro, and basically confirmation of everything I had told you about the new Garmin model focused on ultra-trail.


In a promotional video that was uploaded to Vimeo (and found by the5krunner) we have already been able to see images of how it looks like, and indeed it is a 51mm Fenix 6X (in all probability).

In the video we do not see any new information besides what we already knew, which in short is this:

  • A lightweight model, supported by new straps and the use of titanium in its most expensive version
  • 80 hours of battery life with use of GPS, relying on solar charge
  • 2 months of continuous use in smartwatch mode (again, supported by solar charge)
  • Specific VO2max for trail running
  • Expanded ClimbPro
  • Rest timer on a new ultra-trail profile
  • Recovery time adjusted by other metrics (rest, sleep, etc) — Not new
  • Workout suggestions — Not New
  • Ski profile - Not new
  • MTB dynamics (Grit & Flow)

Here is a gallery with some of the images.

In short, short information beyond putting a face to the small differences that exist from the current Fenix range. That is, the new straps, the yellow ring surrounding the dial and the button in the same color.

And here is the video from Vimeo. If you don't see it, it's been removed.


🔥 🤑 The best prices every day

Anyway, on Tuesday we'll have all the details. In the meantime underneath you have everything I wrote at the time.


I'll start with the first one because the announcement is imminent (within two weeks). From the Garmin Enduro I can tell you practically everything, the only thing I don't have are images of the watch. But everything will be very similar to the Garmin Fenix 6X Solar, with a little more battery life and new software features that will also come to the Fenix 6.

But also some omissions that I will discuss later.

Let's go with the full specs.

  • Power Glass for solar charging
  • 1.4″ screen
  • 51mm diameter
  • Steel or titanium bezel with DLC finish. The titanium version also has buttons and back cover of that material
  • Possibility of a nylon strap
  • Up to 80 hours with GPS use
  • Up to one year of battery life with 3 hours of sunshine per day in maximum illumination conditions
  • Power Manager
  • – NEW – VO2max estimation adapted for trail run
  • – NEW – Ultrarun activity profile
  • – NEW – Rest timer for ultradistance races
  • – NEW – ClimbPro new features. In addition to giving the information about the climbs, now it also gives it of descents and flats
  • Advanced recovery time depending on rest and activity
  • Workour suggestions
  • Barometric altimeter
  • Magnetic compass

Not to say there is also a new medal for a challenge of recording more than 80 hours of race in 30 days. Those 80 hours is not a trivial choice, it is precisely the maximum battery life using GPS announced by the new Garmin Enduro.

Garmin Enduro

Things to consider is there is no WiFi connectivity, which practically eliminates the possibility to offer music playback, because there is no wireless download.

To be taken into account is that no WiFi connectivityThis virtually eliminates the possibility of music playback, because there is no wireless download.

Garmin Enduro

Probably it doesn't have any maps either. At least it's something that doesn't appear in the list of main features. It is strange in the case of a watch intended for ultradistance, but the reason for all this omissions may be in the quest for tremendous extended battery life.

Garmin Enduro

As for the software, there are three new specific features.

VO2Max for trail running

First we have VO2max estimation with specific adaptation for trail running. So far this estimate was not produced in trail run profiles as it was not adapted to make considerations based on the grade.

That is, in the normal running profile the watch records if you run at 4:00 min/km maintaining a heart rate of 150 beats per minute, and will estimate that your VO2max is X (it's a simplification of the algorithm, but it's more or less so).

What happens in trail running? First of all, until now there was no VO2max estimation in those profiles. If you were to use the standard run profile, imaging you are running at 6:00 min/km at 170 beats per minute, but you do it climbing a 12% grade hill. However the watch will not take it into account, so the watch will simply consider that you are running slow and with a high heart rate, so it will lower the VO2max record.

The new algorithm will take these factors into account. What I am unclear is whether it will assign a specific VO2max for trail or provide the data for the general value. It has already been seen in the latest beta firmware of the Fenix 6.

Rest timer

The new ultradistance profile has a rest timer. Its only mission is to record the time you spend on aid stations (or at a lunch/dinner during the race). This will allow you to see more accurate data about running or resting times in the race analysis.

ClimbPro also for flats and descents

Another feature that has been uncovered in the latest Forerunner 945 beta firmware is the ClimbPro new features. So far ClimbPro gave you information about the different climbs ahead, as well as the ongoing climb with details such as grade, graph and remaining distance and positive meters.

As you may well know if you are regular to running in the mountains, running uphill is exhausting, but doing so downhill can be even worse.

ClimbPro on the Garmin Enduro will also offer relevant information for the descents. The graph, what lies ahead, etc.

Remember that to have all this ClimbPro data it is necessary that we have previously uploaded a navigation route. That's where the watch pulls the information from, and it couldn't be otherwise because it wouldn't know where we're going.

Garmin Enduro, price and availability

The official announcement of the Garmin Enduro will take place on February 16th. As for the price, it will not be cheap. You should consider that the watch comes from the Garmin Fenix 6X Pro Solar. The Garmin Enduro version with titanium bezel with DLC and nylon strap will cost $900.

So doing a few quick calculations and comparing with the current Garmin range, we are talking about this approximate prices:

Garmin Enduro – 750€

Garmin Enduro Titanium – 850€

These are not final prices but simply an estimation I'm doing. But I don't think I'm going to be very wrong.


Garmin Forerunner 955 LTE

And what about the Garmin Forerunner 955? Well, little is known beyond that Garmin has already sent a unit to the FCC to pass all the relevant tests. And one of these tests is radio frequency exposure for the different frequencies used, including LTE.

Garmin Forerunner 955 LTE

We're not looking at Garmin's first LTE watch. A few years ago they announced the Vivoactive 3 LTE, but it was associated with the exclusive sale with an operator as it did not yet equip eSIM. Each watch had a physical SIM inside, so distribution was hard.

That Vivoactive 3 LTE was simply a test model for public acceptance. That is, a market research (but with someone else's money).

But it is clear that in this case we will be talking not about a physical SIM, but about offering the watch with the possibility of setting up an eSIM through the mobile phone app.

The big question regarding this model is how Garmin will take advantage of the LTE connection and how it will save power consumption to continue providing reasonable battery life.

Unless Garmin announces the FR955 LTE with some exclusive and important new features, here are the possibilities I can think of:

  • LiveTrack straight from the watch without using a connected phone. It can be useful not only for training but also for racing, depending on the battery life offered
  • Incident notifications in case of fall, etc.
  • Music streaming (such as Spotify), without having to download music beforehand
  • Sending and receiving SMS messages
  • Activity sync straight to Garmin Connect as soon as we finish our workout

LTE is the only type of connection it will offer (in addition to the classic WiFi and Bluetooth, of course), which means that there are no 3g or 2g bands. This will limit quite a lot the use of mobile connection exclusively to urban environments since the deployment of this band in rural areas is not frequent at all.

What I don't think Garmin integrates into the watch will be sending and receiving calls, precisely because it only has LTE connectivity. It won't be a coverage issue exclusively, the operator with whom we are going to use the watch must have VoLTE enabled, which would be another issue to add to the watch itself.


There's plenty of information for you to chew until the Garmin Enduro presentation on February 16th. And if in the meantime you have any doubts or want to ask a question, you already know that you have the comments at the bottom of the page.

And with that... thanks for reading!

  1. hello, thank you and congratulations for the post, you talk about the enduro the date of presentation on February 16. For the 955 LTE I understand that there is no date, but more or less when do you think it will come out?

  2. Hi, Eduardo,

    I love the news of the Forerruner LTE. Not because I'm going to buy it, but I had always thought I would make the jump to a Phoenix when it had cell coverage. To send live geolocation and also for SOS issues, basically.

    What you say about the 4G bands, it is true that it is not so distributed over the territory, but I had understood that essentially 4G networks were better for the mountain because they had higher penetration and lower attenuation. I don't know, I remember in 2019 doing a lot of summits in the Tyrol, no matter how deep I went, I didn't lose 4G on mobile.

    1. Penetration does not depend on the type of technology (2G, 3G, 4G, etc.) but on the frequency used. Before, 4G penetration was very low because high frequency bands were used (1900MHz, 2100MHz, etc). With the entry of 4G in 800MHz this has been solved, but it is more recent and depends on the implementation of each operator.

  3. Thank you for the article.
    The truth is, if in the end it has no maps and it comes out for almost 900€... no matter how much battery it has, I see it as excessive.

    1. I agree. But it is the price escalation we are seeing in Garmin. In this case they would justify it by materials, weight and autonomy. But the lack of maps would be a major omission.

  4. 750€ for the basic version and probably without maps and music...

    I am afraid of the Phoenix 7.

    And except for Coros, right now there is no alternative.....

  5. I think that if Garmin wants to give the final blow to its competitors, apart from the new functions that we advance, they must incorporate the native power to their new watches, I think it is one of the biggest demands today of consumers of this brand.
    Thank you very much for your work and information, best regards Eduardo.

    1. The final blow is being given to the customer's wallet and this gives them to other brands buying expensive watches with features that will never use although it is also shooting up prices in other more basic.Sorry and do not want to sow controversy but after 20 years and seeing the escalation of Garmin as the competition is defeated does not stop impressing me that people do not see what awaits us as Garmin increase its monopoly.

  6. The Garmin enduro will not work in Spain with those frequencies. None of them are compatible with the bands here, and according to these specifications the pod could have WiFi band 2.4.

    I am still amazed at how much these terminals cost and how limited they are in terms of hardware and especially software....

    1. The report is not of the Garmin Enduro, it is of the FR955 LTE which will indeed have WiFi.

      The FCC is the certification agency of the United States, logically there they test the device to be sold in the U.S., here the supported bands will be others.

  7. For those of us who are parents, going for a run with the phone is a must in case something happens to our children in our absence and the poder return as soon as possible. Now with a watch with LTE technology, more maps, more barometer, more heart rate monitor on the wrist, more etc, etc, etc, etc of very useful functions, all in a single device, podré finally go running with nothing more than clothes, shoes and watch. Right now there is no brand that has it, and this garmin 955lte will be the only one on the market.
    Like me, I know that there are many parents who want to run free and free without telephones and have the peace of mind of knowing about our families.

  8. On the official website of Garmin in the Czech Republic the Enduro is already announced as the next release, even its price, at the exchange rate to Euros, about 900, says next and does not put images or features.

      1. Note the link is e7r
        I imagine the enduro e but the 7, from the fenix 7 range?
        These are my conjectures, but it may be closer to the fenix 7 than to the fenix 6.

  9. Sportingly speaking, I hope that the 955 can be configured for personal multisport training, which is what I would like to do as a triathlete, what do you think?
    I have the 935 and it is about to ask for retirement.

    Thanks for the info

    1. What do you mean by multisport training?

      What you can take for granted is that, like the 745, it will have suggested workouts for cycling and running. Maybe it's time to look at suggested swim workouts as well?

      1. I mean poder follow my workouts, for example: in multitransitions, I start my workout on the bike and when you switch to running it doesn't give you the option to follow a running workout.
        I don't know if I'm making myself clear.
        Thank you very much and sorry

        1. Okay, I get your point.

          Well, I don't know if the way the software is "organized" right now it would be possible to do what you are asking for... Probably the answer from Garmin would be to treat it as two different activities.

  10. Great you say the release of the 955 is very close. One question:I run and bike and have done some triathlon,I was waiting for the Garmin 955 but I would like to know if you see better the Garmin 945 /955 (using it for bike and run) or have the garmin 830 for the bike and a cheaper watch for running and swimming.More than anything the question is about the usefulness of the garmin 830 or better to have it all in the watch(and support for the bike). I'll let me know if you can,thank you very much for everything and congratulations for the articles.

  11. Hi all,
    I have searched FCC web page and especially part concerning IPH-03949 (or IPH03949). This is actually Garmin model A03949 which is most probably GArmin Forerunner 955 LTE.
    One of documents states that Short Confidentiality (for pictures etc.) is 90 days from Grant date -> this Grant date (so official date when FCC approves device to be released to public usage) is 02 of Feb 2021.
    So .. it means that we shall see 955 released not later than end of April / begining of May 2021 🙂
    Have nice days 🙂

    1. Hi Greg, thanks for your comment.

      That's a good guesstimate, and official presentation should be shortly before that maximum date.

      HOWEVER, each brand has the possibility to further postpone the publish date if they contact the FCC (but they have to remember to do it). So Garmin may decide to postpone the announcement, and the device be leaked by the FCC. This has happened before.

      But it's strange that happens and I'm pretty sure we'll see the 955 rather sooner than later.

  12. Hello,

    Any update on the possible release date? Greg's comment is very interesting but I don't see much movement on the forums regarding this topic for weeks....


    1. Recently Garmin has moved the date back to June 2, if I remember correctly. So as I replied to Greg, you have to keep in mind that those dates are not fixed and as it has happened, they can be changed by the manufacturer.

  13. Thank you very much for the info! I had not seen the 2-jun. Let's see if in 2 weeks they surprise us hehehehe

  14. Hello, the second quarter of the year is over and we are still without the 955.... there any news?
    Thank you
