Adventures let you import GPS tracks, pictures and videos and make them into a slideshow. I was able to combine each days track and then the checkpoint pictures with position data (I had to edit the location data on the pics as my camera was never on long enough for it to locate any satellites).
It's not quite perfect as some pictures are out of actual sequence due to me often riding past the one checkpoint without stopping on the way to another and then getting the first CP on the way back. Also, if there were a number of CP's fairly close together you can see it display all the pics before going back to following the track.
To get the slideshow into a video format that I could then edit together I had to play it in Basecamp and then use a screen grabber to record it. This worked not to bad except the transitions when pictures load are a bit jerky - maybe if my notebook had a bit more grunt they would be smoother...
Still, reasonably happy with attempt #1.
