I uploaded a workout I did yesterday to Garmin Connect and it is missing roughly the first 2/3rds of the data. The data is all there in Garmin Training Center, so I tried exporting it to a .tcx file from there and uploaded it to Garmin Connect and had the same result, the .tcx export is missing the first 2/3rds of the workout.
Does anybody have any idea what is going on? Why won't Garmin Connect see this data and why doesn't Garmin Training Center export it? I've never had any issues uploading workouts before.
