I've been getting an error where my cycling distance jumps to 8300+km after a short time (it should be about 22km for this route). For some reason it's always around 8300km. The other data points - time, speed etc are good but the distance is wildly off. If I stop the activity and immediately restart, it will record distance normally. The watch is 7 months old and used to measure this route acurately but this problem is coming up more and more and now it happens almost every ride. I frequently ride the same trail out and back and it almost always happens on the way out but never on the way back. Any suggestions?
I have tried:
Updating to the latest firmware
Waiting for a few minutes after it shows the GPS being connected before starting my ride
Starting the GPS a bit farther down the road from my normal spot
Cycling the watch power off / on
Thanks for any help you can provide.
