Multiple gpx files = 1 route?

I received several gpx files from Adventure Cycle. All part of one ride. each file contained either the main route, an alternate route for a section plus one waypoint file. I've looked, and can't find a way to create a route out of those 'lists'. The first dialogue box wants  me to enter waypoint data. The data in the afrementioned gpx files contains all the correct data, why is prompting me to enter?

This may be evident to an experienced user, but I can't figure it out.

Thanks in advance
