I am using a polar pacer watch to track my runs. Then I sync it with Strava.
surprisingly the data does not match btw polar and Strava. If synching I am assuming that the data from polar is basically just pushed to Strava - so basically a copy paste of the data from polar.
But this is not the case and the Strava data shows different pace per km which is really weird.
i don’t have my mobile with me during the run - only my polar watch. So I wonder what is happening there on Strava?
see some pictures.
can someone help understand?
