I recently purchased a Forerunner 610 and am using with a footpod. I'm doing a mix of indoor and outdoor activities.
I started to have "failed to upload" / "server errors" with the ant agent a few days ago after running with a custom workout indoors. The activities would upload to the Garmin Training Center application wihout error.
Upload from GC Upload web page (new or selected) didn't work (the activities appear to be uploading but never finish)
Manual upload of the .fit file fails ("An error occurred with your upload. Please try again."). However, if I export the activity from GTC to a .tcx I can manually upload the file into GC.
So I think that there is something in the .fit file associated with a custom workout that makes GC unhappy. I've attached the .fit and .tcx files for reference. Any suggestions would be appreciated.
Thanks.
