Hi Guys,
I was out with a friend earlier who has a PM fitted, his average over the ride was 196w, whereas strava calculated mine at 138w when he added me to the ride (i didn't record it on strava on my phone and i dont have a PM fitted). Is this purely down to a difference in w/kg (he's 5st heavier) or just stravas calculation of my power over GPS?, or a combination of both perhaps?
