I was tyring to export my activities from the Garming Training Center software and upload them to Garmin Connect but haven't been able to sucessfully do so. I've tried exporting both as .gpx files and as .tcx files and then upload to Connect via the manual import part of the Garmin connect interface. However, I get "An error occurred with your upload. Please try again" everytime I try. Any idea what I'm doing wrong?
Do i have to upload only one activity at a time? (I tried this also, but couldn't get it to work.)
