I thought this website was pretty cool, you can download podcasts of coverage of the Race From Canada to Mexico along the Great Divide Route. The casts are complete with audio from some of the racers calling in as the arrive into the local towns, as well as an interview with a dude who completed the route last year.
enjoy
