On last Sunday’s 10-mile run, I decided to take my wife’s Forerunner 205 with me along with my S625X. I had gotten a new pair of shoes and I was going use the Forerunner to help me calibrate my S625X for the new shoes.

At 5.84 miles, my S625X decided to simply stop recording speed and distance. The HR monitor continued to work just fine. When I got home and offloaded the data, the data ended at the same point that the speed and distance stopped recording.

At first I thought the battery had died, but I didn’t want to stop running to check. I did check when I got home though and the green LED was blinking normally.

I did a 3-mile run today and the S625X worked flawlessly.

Maybe it was just jealous that I took the Forerunner with me
