Suunto 2.50.26 – Q4 2025 Release Notes
-
Hello. Is anyone else having trouble with their Vertical 2 and the advanced heart rate zones for different sports? When I adjust the maximum heart rate for cycling (since it’s lower for that sport), it affects the maximum heart rate for other sports (default, running, etc.), even without selecting the option to update the maximum heart rate after the suggestion message appears.
I’ve consulted the manual, and while it explains the function, it doesn’t seem to work. I don’t know if anyone else has reported this issue… I’m using SFTW version 2.50.26; I didn’t notice this problem in any previous version after adjusting the thresholds.
Also published in Vertical 2 general discussion…
EDIT: For now… I’m not modifying the maximum heart rate while cycling, so it doesn’t alter the other zone programs. -

It is not lower for any sport. There is only one maximum HR.

@Squirrel
I understand that you ride your bike not just for leisure…
Just imagine you’re carrying your weight while running…
In my last lab test on the bike, my heart rate was 15 beats per minute lower than during a run, but oh well, it’s just my body. -

When your HR was 15 beats lower, then you were not able to reach your true HR max while cycling.
If you have bike lab results, then set your LT1 as top of zone 2, LT2 as top of zone 4 and leave max HR at a true universal value. -
@Squirrel HRMax is different for each sport, if you want to have the best estimate of training load. Ideally Suunto should accommodate that, but they do not. So while you only have one highest HRMax, for purposes of computing training load and zones, ideally it should be done on the basis of a separate HRmax for each sport.

@DrSilverthorn „ In comparison to running or rowing, cycling uses less muscle, so local muscle fatigue usually occurs before cardiopulmonary exhaustion.“

This Q4 2025 Suunto update looks huge! The multisport focus is impressive—automatic transitions for Triathlon and SwimRun, circular multisport, and the new ZoneSense features will make training so much smoother. I also love the per-sport persistent settings and the improved optical HR algorithms—it should finally feel closer to chest strap accuracy. The navigation and sensor improvements are a nice touch too, and the demo mode is perfect for in-store use. Overall, seems like a solid upgrade for both casual and serious athletes.

@DrSilverthorn I completely disagree! Zones will change for sports but HR Max is a single value, period! This is physiology.

I managed to initially test the new software in relatively poor weather. Calculating elevation gain in moderate winds finally worked very well. At least, during moderate winds.
And as I mentioned earlier, none of the bugs I’ve been reporting on for many updates have been fixed. Specifically, the inability to change routes during ascent/descent, the crazy breadcrumb, and the occasional lack of updating of the current position on the map.

Hi everyone, thanks for your input. I’ll enter my maximum heart rate achieved in both sports, but I’ll configure different ranges for each discipline since certain muscles or physical qualities are more involved. Thanks for your contributions.

@Brad_Olwin go back and read my original post. We are in violent agreement. That being said, using a single HRmax value for purposes of training load computation, when using multiple sports is suboptimal, and IMO ‘wrong’.

@DrSilverthorn Its not the HRmax that is used for Training Load in my experience, its the zones - especially the thresholds. And those you can set per sport
