I bought Garmin fenix 6x pro before a week and my VO2 max didn't changed after 4 running activities... Could you find a solution for my problem?
Did you use the normal Run activity or the Trailrun activity? Because Vo2Max is only calculated in the normal Run activity. Also, did you set your HR Max correctly? This is important to get an accurate Vo2Max estimate.
I used the normal run activity... I seted only the hr in rest
