Yesterday I tried out a new external GPS (previously I was using my internal GPS). At about 8.5mi into the ride I looked at the phone and the GPS Signal showed a hyphen (-) instead of the usual "good". The GPS seemed to have disconnected so I reconnected. At that time, the distance traveled showed 7.78mi.
I rode a few more miles and when I stopped, the training was still going but the distance traveled still showed 7.78mi and the GPS signal still showed a hyphen. Curious, I uploaded the training anyway and when I looked at it, the route was complete but the data on the graphs stopped recording about 20min before the end of the route.
Can anyone determine from this info whether the issue is with the Run.GPS software, my phone or the new external GPS? I also noticed that the altitude data is no longer there...I am going to switch back to the internal GPS and see if the altitude reappears.
