The CTR: 500 miles and 70,000' of elevation gain winding through the Colorado Rocky Mountains between Denver and Durango. Approximately 300+ miles of singletrack at elevations ranging from 5500' to a gasping-for-breath 13,200'. The CTR is a monster! If the monster is in a good mood, you may experience Colorado's beautiful sunny blue skies and wildflowers blooming as far as you can see! But, be warned — the CTR's mood can change on a whim, and you may just as likely find yourself getting besieged by massive hailstones and lightning bolts. In short, don't come to this race unprepared — no one will be there to rescue you.
- Race from Denver to Durango, self-supported, under only your own power, along the entire CTR route.
- No pre-arranged support, with the exception of maildrops to a post office and only a post office.
- Don't break the law.
