I see in the activity reports of Garmin express, that there are two VO2 Max reports.
The first one is for All activities.
The second is for the Biking activity.
In my case, I only record biking activities. But the VO2 Max for Biking is 0 (the All activities VO2 Max has a value).
Is it normal that there is no Biking VO2 Max computed?
Is it a bug or should I do something special in the watch setup to get it ?
