Forerunner 165 vs Strava distances/ almost 1km different

  1. Hi guys,

I recently bought the Forerunner 165 music and ran with it couple times but I’m still recording also with Strava when I run to check the differences and they are huge.
I don’t understand how it’s possible that the distances are different by almost 1 km:
Garmin 6,76km
Strava 7,64km
It’s the same racing route on both apps though.
Does anyone have the same problem than me ?
