Apologies if I missed the answer to this problem, but the only export option from Garmin Connect appears to be "Export Original", and when I try various .fit file viewing and repair options, it is hit or miss at best.
I've also tried uploading the .FIT files to Training Peaks and other similar software packages, but they all say that the files are corrupt. Everything shows up fine on the dashboard in Garmin Connect, though.
Any help would be greatly appreciated!
