I have a Garmin fenix 2 that gives me an estimate of my VO2max. I use the watch with a Scosche rhythm+ strapped to my arm.
I am interested in knowing how accurate Garmin's estimate is?
Along with the VO2max estimate, Garmin also gives me estimated finish times for standard distances -- 5k, 10k, HM and FM. I know from personal experience that Garmin overestimates my finish time (put otherwise, underestimates my avg. speed).
Any comments or links to analysis would be quite helpful. Thanks!
