My buddy Rafal in Omaha (pronounced Home-Aha) told me about this annual race, the Dirty Kanza 200. It sounds awesome. 200 miles through rolling hills of gravel in Kansas. Over 80% of the participants did not finish last year. WHICH IS AWESOME.
I'm kind of intrigued.
There's a video of 2009's event, but the choice of music is suspect. So you'll want a different soundtrack; I recommend "Roundabout" by Yes. Cue it up by opening this link in a new window and wait for the bass at 0:45.
Then start the Vimeo video -- OBVIOUSLY on mute so you can listen to "Roundabout".
