Back in the days before before fatbikes were common, there was a bike/run/ski race on the Iditarod trail called the Iditasport. In 2002, it was replaced by the Iditarod Trail Invitational. In 2001, the final year of Iditasport, RJ Sauer made a documentary called “A Thin White Line.” The film is now on Vimeo and if you haven’t, you should watch it. I am not in it since I did the race in 2002, but it is very accurate in its portrayal of the trail and racers. When I talk about “type 2 fun” and “I’m not giving up just because it’s hard” it is in direct reference to this film.
