On mile five of my 15 mile run the forerunner 10 simply stopped working. The time continued to run but the distance I was running was not being added to my total distance. I am new to the product and I don't know if this is an ongoing problem or something I did wrong. After messing with it for a few minutes I simply stopped that run and began a new one. The forerunner worked fine the last 10 miles of the run. Did I simply lose satellite coverage? Should I have left it alone and if so would it have picked back up and reentered the mileage that I actually had run? Any help is appreciated.
