@SirMcKey @sportsfreund @brad_olwin Thank you! I’m slowly getting back into online things…

@2b2bff optical HR sensors can never be as accurate as measuring the electrical signal with a chest strap. The higher the heart rate, the shorter the R-R intervals, so the measurement error of optical signal detection are a higher percentage of the R-R interval as the HR increases. This throws the math of ZS way off.

@gipfelkind I found the cause: the Morning Report is triggered by arm movement while I’m still in bed. If I don’t see it and leave it undismissed for an hour, it vanishes and cannot be accessed again that day.

@Brad_Olwin “My Plan” is Suunto’s own approach of a training plan, or is it called differently now? I use the iOS app in German translation, what is still a bit lacking…

@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.

@Ecki-D. But to me, this is definitely a used battery issue, as if i switch on the watch for running, it will turn off instant.

@cumbrian-runner Welcome to the club --> Thread

Tested today with the Coros HR armband, everything seems fine - firmware du Coros : V1.22.0 [image: 1771852447633-img_0483.jpeg]

@Bradleyd Yes, I have the start of the week set to Monday. I don’t see any reason why it should treat Sunday as a rest day.

@cumbrian-runner hi, yeah, I have the newest firmware as well. I did a hard reset and did a 5km test run, and compared the activity with my old garmin forerunner 255 + polar verity sense arm band. Looks much better now, there are some wobbles here and there (like showing up 10bpm higher in around 18minutes), but overall it is pretty good (162 to 163 bpm average). My 5km run: [image: 1771832282797-zrzut-ekranu-2026-02-23-o-08.26.54.png] Climbing the stairs still not quite good, the HR is updated to proper values only after i stop for a while, and yes I had the watch pretty tight on my wrist and a bit above the bone. And to indicate what was going on before hard reset, one of my walks: [image: 1771832233700-zrzut-ekranu-2026-02-23-o-08.36.55.png]

A week on & I’ve done a good mix of walks & runs, some hilly & some flat (48 miles with 5111ft ascent). The Race has reported spot on ascent values throughout so the cleaning process above definitely works

@SuperFlo75, @gipfelkind, Thanks for the answers!

@runomatic Amazing

@galerna do you wear it while sleeping? It starts from a certain value after turning the watch on (idk how that value is calculated) but its intended use is to wear it overnight where it charges during sleep and then while wearing it during the day it discharges when your active/stressed and sometimes charges again when you’re relaxing enough, e.g. taking a nap. It’s not working correctly when you just use the watch during exercise

I can confirm that too. It has been introduced in latest firmware.

@Dima-Pursanov Let’s hope so. It would make the watch a better tool.

@marbjo you might be right about surface time… Also ive found in other groups someone mention the diferences between Ocean and Nautic S ***Thanks for your feedback! The Ocean and Nautic S have different features due to hardware differences. We’re always improving via firmware updates, but some advanced Nautic S functions may not come to the Ocean. Keep your device updated, and feel free to share any feature requests! The Nautic S supports dual transmitter for sidemount diving and be able to display simultaneously the pressure in each of two tanks. The Suunto Ocean currently does not support simultaneous display of two tank pressures for sidemount diving. It can connect to multiple Tank PODs, but only the active gas’s pressure is shown. Unlike the Nautic S, dual‑tank display is not available on Ocean, and there’s no official confirmation it will be added in the future.***

Thanks guys how weird, I haven’t noticed mine doing it in normal mode only when I’m in an activity. I have the latest soft ware. Strange though it’s only started happening in the last week, the last software update was a while back now

@Sportsfreund In my case, it worked very well. On Race, now on V2. But today, it started detecting sleep with 1 hour delay.
