Hi, it seems I'm losing data on my GT 31. Almost each session ends up being 4h30m while most of the time I'm on the water longer than that. Today as well, I had 147.9 km on display for distance, and GPS logging only shows 120 km. Anyone has an idea how to solve this?
I was already thinking about starting a new session on the middle of the day and joining them later on.
Any idea would be appreciated.
