Suunto 2.50.26 – Q4 2025 Release Notes

Zdeněk Hruška

@Dimitrios-Kanellopoulos thank you very much. I think there are more threads regarding the Stryd not working properly with Suunto in this forum as well as on Reddit for example (especially about pace and distance not coming from the pod). I haven’t used Stryd for a few years. I remember that it worked flawlessly before. There are definitely some issues now. And it seems to be the case that on the treadmill it works as it should while on the gps profiles watch seems to prefer gps data. At least from my experience and testing.
Thanks for all the help!
Edit: Also there was a pairing issue with the new 5.0 Stryd but that one had been sorted out by the Stryd update.

@Dimitrios-Kanellopoulos toggle for auto calibration was there the whole time as you said, but it did dissappear at least for Stryd when we got the first firmware version that introduced ability to pair multiple sensors of same type.
Then we just got it back on latest 2.50.26 firmware

Thanks for the info.

Right, disappeared due to Q3 2025 update bug.

Fazua Evation power meter not connectable any more.

With the firmware before this one it was connected with CSCS protocol but without transferring data. And now there is only the name “Fazua Evation” and nothing else. No connection, just the result of the scan process.

On my Spartan Ultra everything is working, I can choose between speed/cadence (CSCS) and piwer/cadence (CPS).

With firmware 2.44.48 everything was fine with 9PP and Vertical. Afterwards no pleasure and just frustration. ️

It cannot be so difficult to implement the both protocols, because it was working before the change of Suunto’s bluetooth stack to several connectable ble devices.

Maybe the programmer from back then can help. 🧐

@pilleus the same problem with the Fazua Ride 60. Very frustrating indeed.

Another software update without fix.
Suunto’s priorities are looking really bad.

@Zdeněk-Hruška My understanding is when stryd is paired as a footpod via Settings - Connectivity, watch uses Stryd distance. And if the calibration is enabled, Stryd distance coefficient can be calibrated by watch GPS distance.

When stryd is not paired as a footpod, it can be connected via S+ Sports App Stryd, in this case, distance is from watch GPS.

Could you test ? Sorry to ask this like this but sold my stryd. And this is kinda the official info. If that doesn’t work, I’ll prio this, we also have a big issue with stryd 5 afaik so let’s batch those 2 if needed.

Good morning and have a great week.

I’m using Suunto Race S with firmware 2.50.26 (Q4 2025) and I’m having serious doubts about sleep tracking accuracy.

Examples:

Night sleep:
I was in bed from 19:11, awake and actively using my phone until ~20:00, but the watch still detected sleep starting at 19:11.
Nap:
I napped from 12:41–13:05, then stayed in bed using my phone until 14:28.
The watch recorded continuous sleep from 12:41–14:28, even though I was clearly awake for over an hour.

It seems the algorithm relies too much on inactivity and lying position, and cannot distinguish between real sleep vs. lying still while awake (phone usage).

As someone who relies on sleep data for training and recovery, this makes the sleep metrics hard to trust.

In my tests, I found that many issues have been fixed.
However, two things have gotten worse.

Sleep tracking: I wake up at 6 AM, walk 3 km in the campsite. The watch was active. Then I came to my tent. My alarm, which I set for 7 AM, went off. I stopped the alarm, and it said “Good morning.” It doesn’t realize I’m awake unless I physically touch the watch. Functions like step counting and location don’t contribute. 2. Increased battery consumption. I think, partly due to the added features, my battery life has dropped to 6 days with daily use.

These are my observations for now.

@Dimitrios-Kanellopoulos thanks for the explanation. I understand the intended behavior and I have tested exactly this setup multiple times.

Unfortunately, my real-world experience is different:
• When using GPS activity profiles, the watch still seems to prefer GPS-derived pace and distance, even when Stryd is paired as a footpod and enabled (autocalibration off).
• This is very noticeable right after activity start:
I can clearly see pace reacting to wrist movement, even though Stryd is connected and active. That strongly suggests pace is coming from the watch, not from the pod.
• On the treadmill, everything works exactly as expected — pace, distance, and power all come from Stryd consistently.

I also regularly experience what looks like a silent connection degradation:
• Stryd appears connected and active
• But during the activity, power is not taken from Stryd
• Example from today:
In Suunto App I see avg power 202 W, while in Stryd PowerCenter (after offline sync) the same run shows 223 W
• The only workaround seems to be:
Forget Stryd → re-pair before the run
Even then, I get power only, while pace/distance still come from GPS.

Another odd thing:
• Autocalibration can only be enabled/disabled immediately after pairing.
• When I later go to Paired Devices, the option is no longer available — I can only see battery status, etc.
This doesn’t feel like intended behavior.

At the moment, the only reliable workaround seems to be using the SuuntoPlus Stryd app, but that comes with limitations (missing other native data fields).

So overall:
• Treadmill = works perfectly
• GPS activities = inconsistent data source selection + connection instability

I agree this probably deserves a deeper look. It is a little bit tricky to test so I may be wrong with some of those use cases. That comes only from my own testing. However I’ve seen very similar reports here on the forum and on Reddit, so I don’t think this is an isolated case or user error. But still might be

Happy to test further if needed and provide logs or comparisons.

Thanks for taking this seriously

@Zdeněk-Hruška I got asked

Two simple tests? Alternatively, anyone with a Stryd can help verify this.
Test setup (outdoor activity, GNSS fixed, Stryd paired as footpod):
1… Watch on the ground, Stryd on the shoe
Start the activity and leave the watch stationary on the ground. Wear the Stryd on a shoe and run around the watch.
Expected result: distance should continue to increase.
2… Stryd on the ground, watch on the wrist
Start the activity and leave the Stryd stationary on the ground. Wear the watch and run around the Stryd.
Expected result: distance should not increase.
