Suunto Software update Q1 (2.53.42)

Manuel Extreme

Now the only thing missing is the ability to set pace zones and threshold heart rate for swimming (currently, TSS(s) load on Suunto is calculated in an unknown way…)

@Dimitrios-Kanellopoulos Great job Mitso and all the Suunto team

Théo Tuphé

Just for info, pace and power zones are still reset when rebooting the watch

Great update tho !

@Dimitrios-Kanellopoulos Awesome update. Thank you very much

Dimitrios-Kanellopoulos One step beyond

Edit: I updated the device on my way home and have just been for a run around the neighbourhood. So far, so good: no technical issues and all the settings have remained the same (options, S+, etc.). I can’t comment on the battery yet; it’s still too early to tell.

@Théo-Tuphé you mean after a firmware update? Because rebooting the watch should not do that

Théo Tuphé

@isazi Didn’t test after rebooting after updating the watch (by holding upper button on Suunto Race S) but before the update yup it resetted pace and power zones, and after updating the watch, the zones were reset again

Théo Tuphé

*only the pace zones (for running), not the power zones, sorry

@Théo-Tuphé yep only pace zones. But at my Vertical2 its after every Softreset the same. All pace Setting reset

@Dimitrios-Kanellopoulos said in Suunto Software update Q1 (2.53.42):

Information about other devices
• Suunto 9 Peak Pro
Due to hardware limitations, Suunto 9 Peak Pro will not receive further software updates adding new features. Its last feature update was released in January 2026. However, the device will continue receiving new watch faces and compatible SuuntoPlus Apps.

@dimitrios-kanellopoulos, I understand the watch hardware limitations, but the last firmware update (January 2026) is really not bug free!

A lots of users have widely reported back light issues, i.e., back light stucks and wont turn off automatically, OHR sensor (still) turns off during night (long-standing bug…)… Personally, I’m still running 2.48.16 since is more stable that 2.50.26.

So, will Suunto address these bugs or a really great watch will stay forever buggy?

@GiPFELKiND weird, my pace zones have not been changed by this update, and nothing has ever changed after rebooting the watch

@GiPFELKiND I have the same issue on my Vertical 2. Pace zones reset every time after a soft reset.

@Dimitrios-Kanellopoulos o
Super update richtig tolle arbeit…
Nur eine Frage zur wachpasen erkennung die fast immer vollständig mit leichtschlaf ausgepügelt wird was immer zu ca.20-50 min mehr schlafzeit bei mir führt… kommt da auch eine Verbesserung oder wurde mit diesem update schon was gemacht?
Vielen Dank

isazi

@Bigb0zz okay, please report the issue properly with pictures and logs and I will forward it.

HonzaS

Thanks for great update!
Why no map update for Race 1? Will it come later?

isazi

@HonzaS not enough resources

HonzaS

@isazi Thanks for explain!

Miroslava

@HonzaS i wait on it a lot off time and nothing i am.so sad

HonzaS

@Miroslava I understand your disappointment. I asked because I sold my previous Race 1 to a colleague. But the update still brings a lot of other improvements. Interestingly, I already have descriptions and POIs on the map, even though I haven’t received any map updates yet. Anyway, the map is finally readable now, and it would be nice to get color-coded hiking trails too.

If you are riding a dead horse, dismount.

As an owner of a 9PP and Vertical it’s time to change. Both watches cannot connect my bike power meter, loose the connection to external heart rate sensors when mounted on the handlebar of the (kick) bike, reset the watch faces to the standard watch faces while syncing with Suunto plus (I reported the bugs several times here in the forum without any results). No fun at all since firmware 2.40.xx. I’ve definitely had enough.

I will stay with the Suunto Sparten Ultra, which is working without all these issues.
