@superweeble True VO2 can be only measured in the lab. Watches, calculators and formulas only give rough estimates: so you can see the trend not the real value.

I have a similar problem: since the last update, my VO2max still blocked. the value stay at 50.9 even if I stopped running during 2 weeks.

@isazi I can confirm that on my next run i got a VO2 max reading, thanks for your help.

thanks to all for the fast response!

@bulkan said in Vo2 levels: The Garmin only takes in count the running (not trail running, hiking…) and cycling and ONLY with heart rate strap if I recall well. Running with HR (no belt necessary for what I remember), cycling with a power meter. And they end up in two separate VO2Max values, one for running and one for cycling.
