Similar frustrating experience here. After almost 5 years of respectable service, last Jan I decided to move away from my Apple Watch 6 (six!) and bought a Suunto Run, mainly for the price + dual-band GPS (hardware details below). After two months of daily use, I’ve to say: [1.] GPS accuracy: spot on; [2.] HR data: simply wrong and useless with or without external sensor; [3.] BT connectivity with iPhone: sub-par and frustrating; [4.] Assistance: just “did you try to uninstall the app?” Yeah, sure… -.-') Regarding 2.: with the external sensor (never an issue with Apple Watch), random spikes here and there in any (literally) run. For example: [image: 1773996357730-img_6447.jpg] In addition, the very same run, with the following heart rate zone break down [image: 1773996465955-img_6447-2.jpg] …has been labeled as “VO2max”, and I did change my “HR and Intensity Zones” settings. Again, this mislabeling happened all the times. This is not acceptable. Without the external monitor, the data are simply unreliable and from time to time, the hr simply jumps at 180bpm at stays there for minutes although the effort is low without any doubt. Regarding 3.: I don’t even know where to start here. GPS data? Fine on Strava, no way to sync it entirely and correctly on iPhone Fitness app. HR data? Fine on Strava again, and again no way to sync it on iPhone Fitness app. Below an example of what I see…always… [image: 1773996971731-screenshot-2026-03-20-at-09.54.56.png] To fix this, I also contacted Suunto’s assistance and, besides the uninstall-reinstall the app, no real solution or even idea of what’s going on. My conclusions: I feel the hardware has potential and the price is clearly very competitive, BUT (big but) it seems to me that Suunto is holding it back software-wise and this is totally a shame.

When the Run was released and they were talking about a new operating system, I thought it would be the beginning of something that would spread to other devices, and the low price would be the downside of being the first to use an immature system. But with the release of OpenSuuntoPlus, which excludes the Run, it seems the Run will remain an unsuccessful experiment. The feeling right now is that the purchase was a mistake and the watch won’t evolve much further. This makes me consider buying another device, possibly from a different brand to avoid these kinds of nonsensical changes, like Coros.

Guys i have the same problem with suunto 9 baro. Everything from coach uploaded in training peaks was shown on my watch on training days. Problem started about a month ago. Contacted suunto through an agent (very helpful by the way) did a lot of restart, forget, reconnect e.t.c. but with no result. Also followed instructions from google search AI mode but with no result either. Any other ideas please? Thanks

@Nelson-Diogo thank you. I reported it.

Check that your sleep time is properly set. If, for any reason, it was reset to 0 - 0 very probably the report won’t popup in the morning

I see the same pattern. During exercise, the heart rate reading is very good, but not during the day or night outside of workouts.

@Brad_Olwin iPhone 15, latest firmware’s and App versions. I can’t help but wonder though, two things I know compared to other suunto watches: The software backend for the Run is completely different from others—evidenced by single-note tones (instead of the delightful “Suunto Song” for alarms), music, and plenty of other bits indicating its its own breed of software This is the first “spring forward” since the release of the Run—so it may be possible this bug hasn’t been noticed because it wasn’t possible before now?

@SimonDe Bonjour j ai le même problème avec la nouvelle version de logiciel j ai toute les peines du monde pour synchroniser les cadrans problème de bluethood je pense. J ai reussi hier j ai reinitialiser la montre . Mais la joie etait de courte durée puisqu aujourd’hui les cadrans ont disparu et impossible de synchroniser de nouveau les cadrans . Bien a vous

My run today was spot on. Used the Run with the Coros HRM and it was exactly the same as the Polar chest strap. Before I had followed the suggestions and uninstalled and reinstalled the app. So it does seem that at least for this run it has eliminated the spiking. However it has been mentioned in previous posts that uninstalling and reinstalling the app solved the problem each time in occured suggesting it is a temporary fix and not a permanent solution. It also doesn’t alter the data that is already present and incorrect from previous runs so I do believe it’s an issue Suunto need to look into.

@ADidier said in Third-party training: @Brad_Olwin, I understand that the old operating system of the Race 2, Vertical 2 requires an addition in the form of additional applications, it was designed like this. I just hope that with this new software platform, Suunto will be able to communicate with third parties such as other watch brands (Garmin, Coros) that do not use Suunto+. In the meantime, I hand transpose my Runna plans into interval training. At the moment, there’s no sign the new OS used for the Run will be continued to be used. The Race 2 and Vertical 2 use the older OS and those watches were released after the Run. The Run OS was described as “an experiment” not as a direct successor.

That would be better for my eyes. [image: 1771490744172-img_0468-1024x1379.png]

@zagazoo just have it as dashboard tile, should be enough? [image: 1771418336501-screenshot_20260218-133830.png]

@zagazoo I emailed Suunto support. At first I got a generic response, then when I insisted I got a slightly less generic one (they told me I should buy the Suunto hr strap lol), and finally the third time they said that indeed there is a compatibility issue on Suunto’s side and that they’ll look into it. You should nudge them too.

@Ckn1010 If you init a running activity with Free mode and config one screen with lap fields, I think it is exactly that you want.
