Hi,
I went for a run a few days ago and when I started my Garmin forerunner 610 had 25% battery. It lasted about 20 minutes of the run, then stopped recording and started bleeping and telling me it had a low battery... which it continued to do until I finished my run about 40 minutes later!!! Strange.
Now, that activity was not was not visible in the history.
I went out for another run and this activity was in the watch history, but Garmin Express said there was an error syncing with Garmin connect. I retried a few times, but now the activity seems to have disappeared from the history on the watch. Any help to recover the activity would be appreciated (it was my longest run ever!!)
