Hi,
I do running training 4-5 times a week with a friend. 2-3 of those are intervals. We do more or less the same kind of runs, or at least very comparable. We also consider ourselves to have approx the same fitness level. Except on Strava, we recently noticed. He has 71, while I have 18. It is also extremely stable around 17-19. Another friend of mine who does a couple of easy runs a week has 30.. Does this make sense? Or might there be some settings which are not set correctly? I have allow Strava to access heart rate data.
Cheers
