For me, load it into Garmin's Mapsource, double-click the track, and select the Invert option.
Done.

I just tried:

gpsbabel -t -i gpx -x reverse -f in.gpx -o gpx -F out-reverse.gpx

It's not reversing, just padding digits on every trkpt...

Fnnnngh

Post by: fuaran on 23 December, 2020, 10:12:28 pm: The command should have the input file before the reverse filter. Otherwise it doesn't have anything to process.
ie
gpsbabel -t -i gpx -f in.gpx -x reverse -o gpx -F out-reverse.gpx

Or try using the GUI?

Does that require signing up for an account?
