I've been wearing the Forerunner 255 for a couple of months now. Just last week it displayed a VO2 max for the first time, and I thought it was pretty high. It now shows as superior and 54. I do exercise regularely, intensive bike rides (not longer than about 50 kilometers), fast walks (1 to 2 hours), and occasionally running. But, I do not understand the VO2 max, because if its at the top high, I do not feel that I am at some kind of elite level.
Like I said, I do not understand how I should read and comprehend the VO2 max, thank you for taking time to explain it for me.
ps.
I have never measured my maximum heart rate and hence Garmin has set a max hr I assume. Sometimes while biking my HR goes up to 171 for example.
