Ultimate Guide to Colorado Trail: Route, Resources, and More

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.

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.
