For two weeks now I have been unable to upload my runs from my Garmin 910XT. The Garmin ANT Agent finds the watch and starts the upload, however half way through the process I get an error message "Last Transfer with device Forerunner 910XT on xxx/05/2014 7:30pm failed" Anyone have any helpful hints?
This usually happens when one of the .fit files that was downloaded from your 910 is corrupt. You can go to the manual upload page and manually upload each of your activities (one at a time) to find the problem file. Once you've isolated it, you can either delete it or you can try to use the fit file repair tool.
