Overview

Colorado Trail Race Overview: Conquer the Ultimate Challenge

The Colorado Trail Race is a beast of a trail, but don’t let that deter you from bikepacking it. This multi-use trail spans 500 miles (529 +/- miles by bike) from Waterton Canyon in Littleton to Durango, Colorado, showcasing breathtaking beauty at nearly every turn. With an average elevation exceeding 10,000 feet, your lungs and legs will be put to the test. Don’t forget your rain jacket—afternoon thunderstorms are a common occurrence.

The Colorado Trail Race will have you traversing six National Forests, six wilderness areas, eight mountain ranges, and five major river systems. Known as one of the most challenging and scenic bikepacking routes in the United States, the Colorado Trail Race is a true test of endurance and skill.

The Challenge of Hike-A-Bike
During the length of the Colorado Trail Race, riders will encountered an average of 70 total miles of Hike-A-Bike (HAB), amounting to 13% of the total distance. If you complete the race in seven days, expect the equivalent of one full day of HAB. This makes dialing in your setup crucial—more weight on the bike means a heavier push. Equally important, ensure your shoes are comfortable and blister-free.

High Altitude Dangers
Riding above 10,000 feet isn’t just tough on your lungs—it comes with serious risks. Altitude sickness can hit fast and derail your ride if you’re not prepared. Afternoon thunderstorms are also more than just a nuisance—they’re dangerous, especially when you’re exposed on high passes. Don’t take these threats lightly.

To help you stay safe and informed, we’ve created in-depth resources on both topics:

Altitude Sickness for Bikepackers | Prevention & Treatment

Lightning Safety for Bikepackers

Know the signs. Plan accordingly. Stay on trail.

Resupply Points
Resupplying on the Colorado Trail Race is relatively straightforward, except for one challenging section. The stretch from Princeton Hot Springs to Silverton is 181 miles, requiring about three days at 60 miles per day. This is likely one of the toughest parts of the race, so be sure to carry extra food. While Princeton Hot Springs and Stagestop Store & Saloon offer limited resupply options, the other locations along the route provide adequate or full-service supplies.

Riding and Touring the Colorado Trail

If you crave singletrack, this trail delivers some of the best riding experiences. However, racing the route means you might not fully savor its beauty. For a more leisurely and enjoyable experience, consider touring the route instead.

Plan Your CTR Adventure
Prepare for the Colorado Trail Race with confidence by leveraging our comprehensive guides, detailed maps, and expert gear recommendations. Whether racing or touring, the CTR promises an unforgettable adventure through some of the most stunning landscapes in the United States.

Colorado Trail Guide

Colorado Trail Race

The Colorado Trail Race (CTR) is an unsanctioned, self-supported bikepacking event that resembles a large group ride. Participants follow a predetermined route, start time, and a brief list of rules. Riders are expected to understand and adhere to the rules, maintaining a gentleman’s agreement to “race” fairly. There are no organizers, checkpoints, or aid stations; each rider is solely responsible for themselves.

The race direction alternates annually. In odd-numbered years, the race travels from South to North (or West to East), starting in Durango. In even-numbered years, it goes from North to South (or East to West), starting in Waterton Canyon.

Suggested Start Date:

The race is usually the 2nd Sunday of August at 4am.

Rules

Bikepacking races, including the Colorado Trail Race (CTR), are generally unsanctioned and free of entry fees and prizes. However, a set of standard rules governs these races to ensure fairness and consistency among participants.

Note: While these are general rules for bikepacking races, each event may have specific rules that can change over time. It’s crucial to review and understand the official rules for each event, which can be found at the link below.

  1. Self-Supported: Riders must complete the entire route under their own power.
  2. Stay on Course: Follow the designated route without deviation.
  3. Be Respectful: Follow all laws and maintain good conduct.
  4. Leave No Trace: Minimize your impact on the environment.

For the official and expanded rules, visit jwookieone. Be sure to read and familiarize yourself with them.

No entry fees, no prizes, and absolutely no support are provided.

SPOT Tracker Set Up

Check out our Spot Tracker Setup Guide to make sure you’re SPOT is properly set up for the event.

SPOT Tracking

While Spot trackers are not mandatory for the Colorado Trail Race (CTR), their use is highly encouraged. Given the trail’s difficulty and the lack of support, having a tracker is a valuable safety measure. If you wish to be included in the race tracking, you can sign up at Trackleaders.com up to one month before the event.

SPOT Rentals

Spot devices are available for rent through Trackleaders.com approximately one month before the race. For more information on renting a tracker, check the Bikepacking.net forums, Facebook groups, or visit Trackleaders.

Thanks to their efforts and the support of their members, we have the privilege of enjoying this incredible trail. Please consider donating, become a member, or joining a work crew of the Colorado Trail Foundation to support their ongoing work and ensure the trail remains in excellent condition.
