In the fitness tab, I am able to do a graphic where my VO2max that came from my Garmin watch is shown.
Unfortunately, it only gives me my VO2max from running only and not cycling, even if I set it to only take cycling activities into account.
It’s a Garmin limitation. The API only provides one value, and if you both run and cycle, it will provide the running value. (There are a few reports of it not doing this; but I’m skeptical).
What you can do is use the activity level value.
On activity screen select Custom, , search for VO2 and use one of the ones that says ‘from garmin activity’
You can then plot this value on charts, and can split it by activity type.
I have noticed that it only sends a value when there’s an actual workout recorded on a compatible Garmin device, so a 3rd party app, eg. Zwift or IndieVelo will not show a value for the day.
sorry for having the screenshots in french
There is also the fact that it still does not appear in the Fitness tab even after selecting cycling in the same VO2maxGarmin thing
