Fenix 5 with firmware 24.10
Today I started a RUN activity. I'm not really sure if I waited for the GPS fix, as I usually do... but I noticed that in Garmin Connect the track on the map starts at "lap 3":
I open the activity fit file with Fit File Repair Tool and for the first 12 minutes there are no GPS data recorded:
Maybe I was wrong and I didn't wait for the GPS fix, but I'm asking why the total mileage is correct and how the Fenix calculated it in the first 2 laps (with the relative pace etc.) if there's no GPS data
