I ran a route from my home this morning, which I have run before, whilst the stats from the watch seem to be correct i.e. time, HR etc, the GPS shows a route in an old quarry about 5 miles away from where I actually ran. What went wrong, I've not had this issue before? Also I can only get data by connecting via bluetooth to my mobile now, plugging to my laptop I can no longer transfer data. My software on both watch and computer are up to date. TIA!
