Suunto 2.50.26 – Q4 2025 Release Notes

Stavrogin

Update went well on Vertical 1 except for two items. One I am used to, but here they are:

Suunto Guides are not available in Custom Sport profiles. Daily workouts created in TP and Intervals are available when I open the profile for a workout, but no guides are present under Suuntoapps. I confirmed I am not crazy by looking at my Race S that has not been updated yet and the guides are all there.
And pace. I had to reenter pace. It had erased my pace data.

Inge Nallsson

@sky-runner OK, thanks for the detailed info. I wrote about the suspected underlying map data observations in the second post - where someone has ‘elevated’ the visibility of a path.

maszop

@Inge-Nallsson The visibility of paths/trails was removed a few updates ago and still hasn’t been restored. This is a huge disappointment. As is the lack of contour lines, which were promised years ago.
Applies to views from 500m.

Lorenzo Pintore

@Stavrogin same issues with custom sports mode also on my updated race s

GiPFELKiND

@Stavrogin suunto Guides are not shown now in custom Sports mode 🫣 what the hell. Why? Are there testers for a new Firmware? Why to remove existed Features now at a custom Sports mode? I need more values while Trailrunning, so i use custom Sports mode.
Downgrade all watches to previous Firmware.
Sorry Suunto! Thats a shame

The update on my SV1 went smoothly.

This is really an annoying bug.
What kind of pace date was removed? Pace zones?

Stavrogin

@Mitch9 Yes the pace zones in Intensity Zones in Training.

I just updated my Race S and it was the same.

No Guides in SuuntoPlus on watches (Race S and Vertical)
Pace Zones reset.

GiPFELKiND

@Stavrogin specific heart rate zones were missing too

GiPFELKiND

@Stavrogin downgrade Firmware fix this bug

duffman19

New “SMART” barometric algorithm
Initial threshold reduced to 2 m (previously 3 m)
Meter-by-meter measurement after the initial threshold
New air/water filtering (wind, rain, humidity, friction)
Elimination of false ascent and descent spikes
Improved altimeter accuracy and stability

Woo-hoo! This is unexpected and good news. I just did a quick water dip test in the sink and the behavior is much improved. I saw only a small deviation in elevation and ascent/descent numbers when dropping the watch into a bowl of water. Previously I would have seen a wild swing like demonstrated here.

Also stoked to see the ascent/descent threshold reduced to 2m. Can’t wait to grab that extra vert. Thanks, Suunto!

Egika

@duffman19 the threshold is reduced and the algo is now counting 0.5m increments instead of 1m after the threshold

No Guides in SuuntoPlus on watches (Race S and Vertical)

I have a custom sport mode based on running. And in fact, in the running mode the Guides section is visible, in the custom mode it is not. But funnily enough one of the Guides has been planned for today and even though I used the custom mode, I was asked whether I wanna use it, what I did.

So, they are usable if planned for today…

atoponce

@GiPFELKiND This isn’t the case for me. Power, pace, and HR zones all remained in place after the upgrade.

MarkusG

@2b2bff Same for me. The guides are still available in my custom mode based on Running. They are not available in custom sport mode based on Trail Running.

I also removed all (I had only 2, no big deal) and created a new one. Same behavior: in Trail Running it was missing.

HR and Pace Zones were not reseted on my Race.

smedberg

@MarkusG I think the guides are visible for custom sport modes that have an interval screen enabled. At least that is the case for my custom sport modes for running. The one I use for interval training, which also have an on-watch-interval-screen enabled, is listing suuntoplus guides. My other custom sport modes don’t

atoponce

@smedberg What do you mean by “interval screen”? Do you mean the lap table or something different?

Tomas5

Now i understand delay. I wouldnt be comfortable to release so many new features just before chrismass holidays too.

Updated on Race 2 without issue, custom sport modes preserved.

smedberg

@atoponce I meant one of these that you can’t customize, but have to have enabled in order to use the “old” interval feature on the watch itself(before suuntoplus)

@Mads-Hintz-Madsen Just did it on my Race I and no hard-reset. Went through the update process just normally

Happy to hear that it is only me (so far) who has experienced this. It seems like I am an outlier and the update went smoothly for others
