VO2MAX declines 8 days in a row, Why?

VO2MAX declines 8 days in a raw, from 62 to 55 Why? What it could be? Sleep score, HR , training over all looks OK as usual.

ok, you will want to set your HR Maximum manually (same with resting) these values don't change much so want them set to a good known value. I don't know why Garmin would lower your maximum HR automatically…

In old days they said the best performance metric is the performance itself. Gratz to your new PB!

Have your max HR changed? Check that the HR zones are the same.

i have the same isue after the 8.2 software update. had 61 and declined to 56. thing is that the suggested values in the training advise are more in line how i actualy train. so i guess it is best to wait and see if it stabilizes.

Decline that I got from 61 to 54 lasted for 10 days in a row, then it stabilized in a range 55-57 for 4th weeks in a row. At the same time threshold declined and this is some kind of explanation of VO2MAX decline. but at the same time I broke PR at 5K twice and still wandering where is the point of truth?))..
