    @Dimitrios-Kanellopoulos Dimitrios, maybe we are mis-communicating? To clarify, I want to upload a FIT workout file (not activity) and secondly I do not have API access. I am not sure what you mean by “official channel of the app”. Are you referring to apizone - how-to-workout-upload (not allowed to include a link)? This seems to be what I need, but I am not allowed to use that. quantified-self which you suggested, only seems to upload activities not workouts. [image: 1779851916171-b3a2e673-9610-4faa-9689-4978fa833070-image.png] intervals.icu uploads workouts but only packaged as a Guide in the format they have selected. Hence my idea about reverse engineering the guide file. I have developed an App for interval training, intended for my personal use. But without any mechanism to change settings, it would require me to create different versions of the app for different sessions. I might do that for now but it does not seem like a good long-term approach. As a suggestion… I have an Apple Developer license which I am paying a nominal fee for. That gives me access to all Apple tools and infrastructure. I can download my apps directly to my phone and keep them there for a year, and I do not have to put my apps on the AppStore. I would very much like Suunto to do something similar and I would be willing to pay for a service like that.

    @Stavrogin I understand, and I’m sorry too for sounding a bit sarcastic earlier. I actually did search before asking. I was mainly looking for more recent experiences or newer strap models that people are using successfully now. I just wanted to avoid buying another one that works fine at first, then starts losing HR data after during runs

    @dreamer_ when you mention beacons, do you mean course markings - that is how it is called in United States - usually a combination of turn signs and ribbons to make sure that you are on the course. I still use navigation for two reasons: To have elevation profile, climb guidance, and distances to aid stations. To boost confidence in case I haven’t seen course markings for some time. Also, occasionally, course markings get tampered with or blown away by wind. Perhaps, during a race I spend less time on the map screen and more time on the elevation profile, especially now that it can also show distances to upcoming waypoints. So in a way, the elevation profile is almost equivalent to Garmin’s Up Ahead feature (but sadly without waypoint names, which I think Suunto should add). But during a long training run I spend more time on the map screen because I tend to have a unique route for each long run that is specially tailored to my distance and elevation goals for that run.

    @joaquin there’s one thing. About the measuring wheel. I understand you are being sure that is well calibrated. I know that this can be a very silly question and I was not going to ask, but there’s no reference at the posts about how you ensured the calibration and the wheel is the reference (and the possible point of failure). Just for that to keep everything detailed. Thank you so much

    Best Suunto watch so far (3 years anniversary), after t6c and Ambit 3 Vertical. It fully satisfied my need (I prefer having fartlek sessions over fine-grained training plans, so I am probably missing many advanced features). Never got a single crash. Just got disappointed by the OHR hardware quality.

    @dreamer_ good suggestion, I don’t have access to an android device but I agree that would be ideal. I can try my wife’s iPhone running iOS 17 (I think). Appreciate the suggestion.

    One thing that caused my grief when working with subscribed signals (HR, pace) in main.js or in onLoad is that on the simulator signals are always available. On the watch subscribed signals seem to transition from ‘undefined’ -> ‘NaN’ -> a valid number. I ended up needing to protect any use of these signals by using isFinite(), like this. // Get the index of the the active zone for a 5 zone HR gauge // v current value // zones an array of 4-values defining the 5 zones function getActiveZone(v, zones) { if (!isFinite(v)) return 0; for (var i = 1; i < zones.length; i++) { if (v < zones[i]) return i - 1; } return zones.length - 1; } Inserting systemEvent() was quite effective in pinpointing the point of failure once I understood how to do it. But I do not really get any error message, just something like this. [MR] messages are inserted by me, so I can see something happened after “G4a”, but not what the actual error was. #3251371 26.05.2026 17:44:39 : EVT UI_FRAMEWORK : JS [MR] G1 #3251372 26.05.2026 17:44:39 : EVT UI_FRAMEWORK : JS [MR] G2 #3251373 26.05.2026 17:44:39 : EVT UI_FRAMEWORK : JS [MR] G3 #3251374 26.05.2026 17:44:39 : EVT UI_FRAMEWORK : JS [MR] G4a1-not-supported #3251375 26.05.2026 17:44:39 : WRN UI_FRAMEWORK : JS I am more of a Swift or C# person used to verbose error messages and traceback. But maybe I have been spoiled.

    @elbee thank you so much for the very detailed answer. That 5% per hour with dual band and using maps is not that bad. It seems better than I thought. I understand that before the update battery life was more similar to the numbers Suunto says.

    @garyt687 When setting compass bearing at surface, sometimes u descend and it undoes the bearing. I know in manila it says stay in compass view - but it has sometimes reset on me even in that screen as soon as dive starts. This is useless. We want to set things and leave them not have a computer decide to turn them off 10 seconds afterwards. Please change that The Compass Bearing is active for 5 Minutes above water. Then Suunto resets the bearing. I have noted this also as something that can eaily confuse people setting the Bearing at the parking and during walk to the water entrance will loose the bearing fix. Suunto should fix that.But I overcome this by setting my bearing jsut before going under water. Within 5 minutes and under water it remains active and set.

    @Highlands said in Suunto Vertical 1 – A Few Questions About the Future + Questions About the Vertical 2 and a Comparison with the Coros Nomad / the New Vertix 2026: @dreamer_ I hope they put a sapphire crystal on R2S. About this, I think my wife’s 46mm Run could fit a 1.4 inches screen. Perhaps they could fit that screen aize in the Race 2 S playing with the bezels and making you think the watch is not that “S” but something comparable to a Fenix 8 47mm . That simple change would make a lot of noise for marketing in my opinion and very likely much better sales (just for that)

    @Joaquin Be careful not to chase perfection and in the end nothing is completed. The komoot route is a bit cumbersome and komoot is far from perfect (even if I tell komoot to not change the route, the route on my suunto race s is different than on my wife’s apple watch.) The garmin/wahoo way (select a gpx file and use the open with app) would be an improvement, even if not all tbt alerts are perfect. My first gps watch (a ambit 3 sport) only had breadcrumb navigation. Did I ever got lost? No. My watch after that, a forerunner 935, had breadcrumb and tbt alerts. (Which didn’t work well. A route could only have 50 navigation alerts and if you did your route reversed you lost all tbt alerts). Did I ever got lost? No. My first watch with maps (a forerunner 965) and having some context is nice. Eventually garmin fixed the 50 alert limit, but not the reverse problem and they introduced a timing bug (up to 10k the alerts are before a corner, after 20k alerts are in a corner, or after). And yes, on a twisty road you get alerts for every corner. Did I ever get lost? No. Now I have a suunto. Komoot is fine, but could be better. Autodetect of going reverse is good. No problem if I do a round route and the end is detected before the start (garmin has problems with this. Navigations stops when you reach the goal, which could be before you actually started). Autozoom actually works as one would except (garmin had autozoom, but that doesn’t work, or not as one should expect). But do I get lost ever? No. In the end, all are equally good in the “do not get lost” requirement. Is everything perfect? No. But don”t wait until everything is perfect. Release small steps. Get feedback. Improve some more.

    @Squirrel completely agree. In fact, at this moment is very likely the Race and Race S are the only watches of the market without the white/red implementation. It’s not something critical, of course. But now everybody seems to like the flashlight in the watch, it’s one of those details that are very visible

    @Dimitrios-Kanellopoulos Another crash today at 11:45 CET. Logs sent at 11:52 CET. Watch used Vertical 2. I’ll send you my mail in PM. So far with the current FW both my R2 and V2 are crashing every 3,4 runs. Custom trail run mode Runna guide selected Navigation route selected without turn by turn Burner and ZoneSense Plus apps External Polar H10 V2 connected to Android (today’s logs sent) while R2 to iOS Details: Upon receiving of the “thanks for running with runna” notification I was heading towards the end of the route and was waiting for the end notification. The runna notification never disappeared. What I have noticed is that the notifications with this FW are not going away automatically (most of the time but not always) until mid button pressed. The details of the run in the application are missing: all the Suunto plus data (burner) and the asc/dsc are both 0. Technique part is missing too. Any news of a hotfix coming or should I downgrade? I’ll be switching to the Ocean for now and the training season, if that doesn’t work back to the Forerunnner. Thank for your help!

    How unfortunate that with the latest and last firmware, heart rate measurement stopping has become so much more frequent. Before it was extremely rare, at least for me but now it seems like it’s a weekly occurrence.
