I ran a marathon two days ago. The battery on my Venu did not quite make it through the race, and so the watch shut down at 25.5 mi. Happily, the run activity did save up to that point and uploaded on to my phone and Garmin Connect.
However, since then, I have not been able to get the GPS to connect, either in a walking or running activity - I have been outside and let it attempt to connect for over 10 minutes. I have tried turning the watch off and on and that did not fix the problem. I don't know that the fact that the watch battery ran out is the problem, but it is hard to avoid thinking there is a connection.
I have GPS version 4.80, which must have loaded before the race because I haven't had any software updates since then.
Any ideas how I can fix this?
