I ran this morning and the run is in my history on my 310XT. But it will not upload. Older and more recent activities will, but not this one run. Anybody able to help solve this odd dilemma?
Assuming you have it attached, there could be corrupt data on the device that is causing the problem with uploading to GC and to Training Center. If you don't mind losing your history, try deleting all history and trying again.
Well, I have deleted everything else because I was tired of uploading duplicates every time I tried to get yesterday's run uploaded. But both older and newer runs successfully uploaded. So it seems to be just the one run only.
