2 weeks of cycling - no Anaeroob or VO2 Max readings during the courses.

Hi,

Been cycling for 2 weeks now and I have no VO2 max and never go into zone 4 or 5 while I have the idea, I am pushing my max in cadence and speed when I am cycling. When I used Polar, I used to do these condition tests (which were simple recordings of heartrate, standing and in rest) and that would set my Aeroob and anaeroob baselines.

-is there a test - functionality to do this on the Fenix 8?

thanks for you your help
