GPSBabel can do the conversion, but it needs a bit of fine tuning. These gpx files were created by National Geographic TOPO and include not only the main route but one or more alternates. The alternate paths confuse the GPSBabel conversion and that is where the fine tuning comes in. Even with the alternate paths removed, the main track is 511 points - an inconvenient number. I have only looked at the first section - D1 - and it follows some existing roads here and there so I'm sure the number of points can be safely reduced. Overall, the track looks fine. Some of the altitude data seems mangled by the conversion process.
explains their feeling about the gpx format. A little silly, IMO.
I will continue to work on these. I have the first segment nearly done, just adding the alternate paths. If anyone is interested, let me know.
