3.21.14 Rolling out
-
Staged update starting on September 29, 2025
This update brings improvements and bug fixes.New Features:
- Added support for the “vertical running” exercise mode.
- Added two shortcut opening methods on watch face page.
- Added the function of being able to find the watch through the App.
Optimization and improvement:
- The heart rate algorithm has been optimized, significantly enhancing the accuracy of heart rate measurement;
- The experience of structured interval training has been improved;
- The notification experience after waking up in the morning has been optimized;
- The stability of the system has been enhanced
-
Édit:
-
I still need to use it in an actual session to see how well it works, but the interval training main screen does look clearer from initial check. Here’s how it looks on previous version on the left vs this new one on the right:
I was hoping with this update that we’d also see the ability to customise the other screens though like in regular sports modes
Edit: also found an article about this update that indicates there is a 5-sec countdown and out-of-range alerts for intervaals which would be welcome additions.

@Hari-Seldon Happy to hear that the heart rate measurement has been improved

This is a function I would love to have available for all models.

@OutdoorMan not so important for me, as the watch is either on my arm or on the charger. No other options
-
@Egika well I very often loose things and managed to loose my watch once. This would help
-
@owend very very nice and clear 🤩 hope it will be implemented also in FW version 2.xx of other watches (even if i already know this will remain a dream)

I’m glad to know that the altitude in the profile is purely barometric…

“I would like to know when it will be possible for the beta plans to directly create the guides for Suunto Run.”

IMHO with this update I receive too much alerts during my run. Is there a way to reduce that?

I’m a new user — I’ve been using the Suunto Run for two weeks, running firmware version 3.21.14, and I have two issues I’d like to ask for help with:
The watch occasionally restarts on its own, without any clear reason.
Even in “Treadmill” mode, the watch activates the GPS and tries to measure the workout distance using GPS instead of the internal sensors (accelerometer).
Any recommendations?

It’s rather odd it uses GPS when using the treadmill, never happened here. Since it also restarts, I suggest contacting support for a check.
