@dreamer_ @dreamer_ said in Race 2 accuracy: @Joaquin this is very interesting. Btw, it’d be really nice if you could also add the Race S to the test (not for the shots here but to have internal tests for you now you are doing all this work) and also switch the position of all watches several times in the arm, so you know what are exactly the measurings of all watches in the very same position. I know it means many runs but it also means that you have the very same references several times for all (I think). Thank you so much for this. Race S is super accurate device is a small but powerful machine.

@dreamer_ You were right: Pace 4 - black crystal and cloud white. https://x.com/corosjapan/status/2057639416659947996?s=46

@2b2bff well well well … if you tell to someone who is doing a diet that he lost 5000 g and to his wife that she lost 5 kg … you are right … this is not the same … the wife will be super happy but the man wearing a suunto and for who 43 and 43.0 make a difference will start to question himself about the precision of instrument … how it could have been possible that he arrives preciselly to exact 5000 Joking !!!

@cosme.costa said in Strap/Band color suggestion for 90th Anniversary Edition: I do not agree that Suunto’s textile strap is low quality. There are two reasons why I wrote that: The metal clasp at the end of the strap fell off within a few weeks. I was able to fix it back with pliers, but that felt cheap! it came with 2 straps included - a short one and a long one. Well, the short one was too short and the long one was borderline too long. After a couple of months of wearing it, the strap lose a little bit of elasticity that it had and stretched out, so now it was way too long for my wrist. Also, because there no longer was any elastisticity, sometimes it felt uncomfortable on multi-hour trail runs. My wrists aren’t meaty. In comparison, the 90th anniversary strap feels so much more comfortable. It is very similar to Garmin Ultrafit strap too that I used for several years in the past.

Have to say, what you don’t know you cannot miss. But last year, in a very dark hotelroom, the screenflashlight of my race s was sufficient for my wife to find something on the table while I could stay in bed. So, for now, I’m in “what’s all the fuss about” mode. The digital crown of my race s is complex. Just using it to scroll up or down through menus or items is hideous. The 5 button layout of my previous garmin was better, but with touchscreen I don’t use the buttons very often. But to zoom in and out in a map it’s great. Again with a but. I was used to zoom on the garmin and it was horrible. Complex and buggy as hell. So is the crown just better that worst case garmin or would a 5 button Suunto implementation beat the digital crown? Might. perhaps. Not unlikely. Have to say, the race s provides the features I want in the smallest possible case, so the vertical 2 wouldn’t be competition for my race s (for me). So 5 buttons or a digital crown wasn’t a consideration. Have to say, 5 buttons shouts a bit more outdoorsy and a digital crown a bit more watch like.

@Feissty Maybe a trivial question: Have you enabled location services on your smartphone, and does the Suunto app also have permission to access your location? At least on Android — unfortunately, I can’t say how it works on Apple devices. A simple test is to tap the map icon at the bottom of the list in the Suunto app. You should then see your location displayed on the map. [image: 1779457690263-screenshot_20260522_153607_suunto.jpg]

Figure out your Lactate Threshold - like a recent 5km race without any elevation, average HR of the last 3km - and set the zones according to this article: https://us.suunto.com/blogs/blog/figure-out-your-training-zones-and-supercharge-your-fitness

@suuntastic totally agree with your comment about the phony watch.

Well, I just tried out the custom multisport mode. It was a bust—the watch didn’t detect the switch between running and swimming. I’ll try switching modes manually. It’s losing its appeal… It might have something to do with not switching modes, but the open-water track is full of glitches. I didn’t have this problem during my other open-water sessions. [image: 1779466631129-nage.png] I didn’t zigzag that much, though I’ll admit I don’t always swim in a straight line .

No day without another new vibecoded service. This one is at least more-Suunto specific, not yet another “I made MCP server so you can connect Claude to your Suunto data” (then repeat spam post for Garmin/Coros/etc.) It’s great that people are doing various services, but seems like LLM made this so easy that people not thinking enough about the implications. Vibecode first, market second, reasoning later if ever. But yeah, already think on making paid options What’s the point of the service? What it adds in comparison with Suunto App? Majority of the users sync their Suunto Watch with Suunto App, so even if some third-party service can extract and upload watchfaces, they will likely by overwritten when user sync his watch to SA. Or if they care to change IDs then you can end up with duplicates. And I can continue with other questions, like what happens if Suunto do changes to WF API/format. Then you can break something in the watch using third-party service like this. Find out how to make custom WF? OK, same as above, the fact that you can find out, doesn’t mean it’s good - maybe Suunto is not releasing it because it’s not yet ready for general audience and risky to break the watch. All in all, for the author: good catch to reverse engineer the protocol, for ordinary users: beware.

As it might help someone else that stumbles on the same problem… At least for me it was this Win11 setting that changed things for the better: [image: 1779361611853-34c5e7c4-b6da-4083-9a1f-d14850795012-image.png] Seems stupid in hindsight, but I was not aware that Default only identifies low-power connectivity Bluetooth devices. Happy days! no I will be able to test my apps!

@Tieutieu said in New on Dev-side..... Race Pacer with planned segments/paces: the only “issue” you could have with your preload plan is that even if you plan your 2,45km @5:19/km segment like in your exemple, on the field there is a lot of chances that your segment will not be 2,45km Yes, as someone who uses navigation routes extensively I can tell that whatever distance was planned, it always end up being inaccurate. In my experience, when running on trails, planned distances can easily be 5% too short. For example, If the on-the-route distance to a waypoint was 20 km, it reality it can end up being 21 km.

@aiv4r Thank you! I’m now looking for AirBnB accommodation for the UTA 22 next year I love this watch but I’m kicking myself for not trying on the Race 2 and the updated bands at the Suunto stand…

The models of garmin that are testen in a scientific way (not by some sport gadget blogger) shows that hrv isn’t that accurate on those models. (See https://the5krunner.com/2026/05/05/forerunner-265-hrv-study/ , links to sources on that page) I have no reason to believe other models or other brands are more accurate.

Hi everyone, I think my problem was that I had configured the screens and synced them, but when I tried the mode without GPS, it wouldn’t start the custom views, and I only had a few bits of information. Yesterday, while sorting through my data, I got my custom displays. However, now in the Suunto app view, I have no details at all… just an error message… and the Strava sync, TrainingPeaks, tells me I only ran 6km instead of 10… Ugh… you chase one problem and another pops up. But so my original problem is solved… or at least it seems so. Thanks everyone.

@2b2bff Super mega thanks !!!

said in Suunto Spark: I did not comment but I’m testing my Spark. So feedback post: Sound quality is really good. Build quality is very nice. They feel really premium. Not so good things: The touch is too sensitive. I have disabled by default the “one click” Audio notifications are exactly the same as without the Spark. I knew that, but I didn’t expect the latin american spanish for Spain. Metrics are not integrated with the watch. I think the S+ app should have two more options: An option to toggle on/off things like navigation audio indications, so users can decide if they want the navigation audio indications (which are very useful in several cases). For that, Suunto should implement the feature (which is still missing). An option to toggle on/off to use the metrics taken from the Spark’s pedometers in the main activity in the watch. I mean, to not have 2 activities in the app (watch and spark). Something similar that what happens when you are using a chest/arm strap. Only one activity with the much better bpm taken from the chest/armstrap, not two activities. Something similar happens here with the Spark, since you have 2 additional pedometers that are going to work a lot better than something that is taken from a watch that is in one moving arm. For someone that made the effort of buying the Spark, I see this as an important software bug that should be solved. Having 2 individual activities has not sense (at all). Ideally: Go further with a firmware update for using the pedometers of the spark for indoor/treadmill runs, if possible of course. Things like voice notes while on workout (if possible). Just those little things for making the Spark a must and a perfect companion. About the voice things. Garmin, Amazfit and since this May, now Coros are working seriously on this. This is Coros’ May update: https://eu.coros.com/stories/coros-metrics/c/may-2026 It is very interesting for several scenarios (I.E, running with gloves in winter but see Coros notes). I think the Spark have a lot of potential here and Suunto should really think in the integration as an ecosystem. There are many use cases considering also the integrated pods. There’s a lot of marketing with these things, but at the end Suunto is behind the rest and the integration thing is somehow super interesting considering Suunto has it’s own headsets.

@2b2bff said in Sync Sleep and HRV data to TrainingPeaks: @JSampson wished you had read the thread properly. As Runalyze can get the data it seems like an incomplete implementation of the Suunto API at TrainingPeaks… So, Suunto isn’t to be blamed - in this case… Also Intervals.icu gets all the data, Sleep, HRV, Resting HR…
