Hi, I have a Garmin Forerunner 10 which on the whole I am extremely happy with. However on 2 occassions now it has stopped measuring distance mid run. There is still battery left and the clock keeps going ... but the distance doesn't move.
Frustratingly it happended the first time during my first marathon, when it stopped at 22 miles. This morning it stopped at 16 miles into an 18 mile training run. It also means when you get home and download your run .. it gets the average speed all wrong as it calculates it on the 16 miles rather than the 18 (even when you manually change the 16 to 18 it leave the average wrong).
Has anyone come across this difficulty and got any advice?
Many thanks
Chris
