COLORADO TRAIL GUIDE - BIKEPACKING – One of Seven Project

Embarking on the Colorado Trail Race (CTR) is a thrilling yet daunting endeavor. The sheer length, high altitudes, and challenging terrain can seem intimidating, but with thorough preparation, you can transform anxiety into confidence. It all starts with having the right information and a well-structured plan to guide you through each stage of your journey.

This page provides a straightforward overview of the Colorado Trail Race. During my own experiences on the CTR, I identified the need for a guide specifically tailored for bikepackers. To address this, I’ve segmented the route into simple sections to help you easily grasp the essentials. This page is part of a comprehensive guide designed to let you focus on riding your bike rather than spending countless hours searching for information.

Wondering where to start? This Colorado Trail Race Guide is an excellent entry point. For more detailed information, explore our CTR Planning Guide and Resupply Guide. You’ll find in-depth resources on resupply, transportation, gear, and much more. Dive into our resources and equip yourself for a successful adventure!

Colorado Trail Race Rider Survey

The Project conducts an ongoing rider survey to assist new riders in selecting the right gear for the Colorado Trail Race. Embarking on an adventure like the CTR can be daunting, and the planning process overwhelming. We hope this survey will aid new riders in their preparation and execution of their Colorado Trail ride, ensuring they are better equipped for their adventure.

Overview

Colorado Trail Race Overview: Conquer the Ultimate Challenge

The Colorado Trail 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 (CTR) 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 CTR 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.

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 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.

Self-Supported: Riders must complete the entire route under their own power.
Stay on Course: Follow the designated route without deviation.
Be Respectful: Follow all laws and maintain good conduct.
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 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.

COLORADO TRAIL RACE PLANNING AIDS

Welcome to The Project’s Planning Aids, designed to bridge the gap left by the lack of high-quality planning tools within bikepacking. As a Triple Crown thru-hiker, I’m accustomed to comprehensive planning resources, and I noticed that bikepacking needed similar quality tools. That’s why I developed these resources to make your Colorado Trail adventure as smooth and well-prepared as possible.
Our planning aids include four distinct styles to help you plan your ride:

The Data Sheet offers the most detailed information, including distance, elevation +/-, resupply options, notes and more for key POI.
Town List provides cumulative distances between POI, and does the math so you don’t have to.
Mileage Chart and Elevation Gain Chart are simple graphs showing cumulative mileage and elevation gain between POI.

Each tool serves a unique purpose to support your planning and navigation needs.

Explore our offerings to find the perfect combination for your needs and get ready to conquer the CTR! Don’t forget to checkout our online Colorado Trail Resources as well.

IMPORTANT NOTES:

The race runs southbound/westbound on years ending in an even number and those planning aids have a BLUE band.
The race runs northbound/eastbound on years ending in an odd number and those planning aids have an RED band.
All planning aids are based off the 10k GPX file.
