2023 Colorado Trail Race

The Colorado Trail features 500 miles and 70,000′ of elevation gain winding through the Colorado Rocky Mountains between Durango and Denver. Approximately 300+ miles of the route are on singletrack at elevations ranging from 5500′ to a hypoxic 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.

The CTR is similar to The Arizona Trail 300 and Tour Divide. There is no entry fee, no support, no registration, and no prize money. It is a self-timed ITT (Individual Time Trial). All that is provided is a route description, a suggested start time, and a list of results. However, all individuals participating are strongly encouraged to donate time or money to the Colorado Trail Foundation. Without them, we wouldn’t have this trail!
