I have seen where some of the admins on this forum are able to save corrupt tcx files. This should be a 60mi ride with ~7k of climbing but it will not upload to GC from my 705
I uploaded it to two programs, and both gave the same results -- about a 23 mile ride, with about 2600 feet of climbing. I've attached a zipped tcx file with this part of the ride.
Not sure what happened to the rest of the ride. I took a quick look at the tcx file you posted. It looks like there are some lap summaries -- one ~25 mile lap before the valid 23 mile segment, and two short laps (a mile or two) after. I'm not sure what was going on. These laps might have been causing the file to be corrupt.
