Suunto 2.50.26 – Q4 2025 Release Notes
-
@EzioAuditore Interesting
I just did that and my schedule already was set to 22:00 - 8:00, but let’s see what happens 
-
@OutdoorMan I always get mine after I’ve turned off my alarm and gone to the bathroom. I usually get up at 4:45, even though the clock is also set to sleep mode from 10 PM to 8 AM. I only have that enabled so the display doesn’t keep turning on at night.

@Sportsfreund I don’t understand German and I am not going to translate it, sorry.
-
@EzioAuditore So it seems to be working. Thanks for the hint, helped a lot

@OutdoorMan My browser does that automatically. Sorry.
-
@OutdoorMan Cool. You’re most welcome.

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.
