Are you curious about exploring the Colorado Trail by bike?
I raced it as part of my Bikepacking Triple Crown (Arizona Trail, Tour Divide, and Colorado Trail) in 2017. Amazing doesn’t start to describe the experience. It did take a lot of planning though. So if you have a desire to race or tour the Colorado Trail (CT), read on to learn more with this Colorado Trail Guide.
I pull the following information together for people like us, the explores and adventurers. After my CTR I realized there was a need for a Colorado Trail Guide for bikepackers. This page is divided up into simple sections so you can quickly get a feel for the route. As part of a larger all inclusive guide, this page and corresponding pages will allow you to focus on riding your bike instead of searching the internet for hours on end.
Where does one start the planning process? This page is a great starting point, but if you want more information, checkout the “CTR Resources” button below. Watch out though, you just might find yourself on the starting line in July!

Overview
The Colorado Trail is a monster of a trail, but this shouldn’t sway you from bikepacking it. The Colorado Trail is a multi use trail that runs 500 miles (539 by bicycle) from Waterton Canyon in Littleton, Colorado to Durango, Colorado. It holds immense beauty around almost every turn. With an average elevation of over 10,000 feet your lungs and legs will be tested. Bring your rain jacket, you will get caught in afternoon thunder storms.
Your race/tour of the CT will involve you crossing six National Forests, six wilderness areas, eight mountain ranges, and five major river systems. The Colorado Trail Race (CTR) is known as one of the hardest, if not the hardest and most scenic bikepacking routes in the entire United States.
During the 2017 CTR the average amount of H.A.B (Hike-A-Bike) was about 70 miles. That equals 13% of the total distance. If you were to complete the race in seven days, one day of the seven would be HAB! With this in mind be sure you’ve dialed in your set up. More weight on the bike means a heavier push. Even more important, make sure your shoes are comfortable and don’t give you blisters.
Resupply on the CTR is fairly easy except for one section. From Princeton Hot Springs to Silverton it’s 183 miles. That’s around three days at 60 miles a day. This is probably the hardest section of the entire race. You’ll want to be sure you have extra food. Princeton Hot Springs and Stagestop Store & Saloon have the smallest options for resupply, while the rest are either full service or have adequate supply options.
If singletrack is what you’re looking for, then this is the trail for you. The riding is simply amazing, but know that at race pace you may not be able to enjoy much of it. Touring the route might be a better option.

COLORADO TRAIL RACE
COLORADO TRAIL RACE
The CTR is not organized or sanctioned in any fashion. It’s seen as big group ride that follows a predetermine route, start time, a short list of rules and that’s it. Those who partake should understand the rules and obey the gentleman’s agreement to “race” fairly. There are no organizers, checkpoints, and or aid of any kind. You’re souly responsible for yourself.
The Colorado Trail Race starts in either Waterton Canyon or Durango depending on the year. On odd numbered years the race travels South to North (or West to East) and on even numbered years it travels North to South (or East to West).
Sign up by using the 2019 entry form.
Suggested Start Date:
Saturday, July 26th, 2019
4 am – Waterton Canyon
RULES
Bikepack racing is usually not organized, is without entry fees or prizes, but there are a set of rules all bikepacking races follow. The rules are put into place to create a level playing field for all those who participate.
*Note these rules are the general rules for bikepack racing and each event may have their own specific rules and they also change from time to time. With that said it’s important you read and understand the official rules which can be found at the link below.
1. One must complete the entire route under their own power.
2. Outside support is not allowed.
3. No caching of food/supplies ahead of time.
4. No use of motorized transportation or hitch-hiking, EXCEPT for travel to hospital/medical care.
The following are allowed, but not encouraged. Please use sparingly.
5. Unplanned assistance from other racers is ACCEPTABLE.
6. Trail magic OK – but please, no begging or fishing (hinting).
7. Mailing resupplies ahead to Post Offices is ACCEPTABLE (but some racers frown upon this).
Official rules found at Climbing Dreams.
No entry fee, no prizes, absolutely no support
SPOT TRACKING
You are encouraged to use a Spot tracker, (they are not mandatory). Due to the nature, difficulty and lack of support, I personal believe you’d be nuts not to. If you want to be included in the tracking of the race, you can sign up at Trackleaders.com one month before.
SPOT HIRE
Spot Gen3 are available from Trackleaders.com around one month before the start of the race, if you’re looking to rent one. Check Bikepacking.net forums, Facebook or Trackleaders for more information.
SUPPORT THE COLORADO TRAIL FOUNDATION
The Colorado Trail Foundation has no affiliation to the race but they are the acting stewards of the trail and help manage/maintain it. Because of them and their members you have this amazing trail to ride. Please consider donating or joining the Colorado Trail Foundation, so they may continue their amazing work.
2020 Data Sheets, Town Lists, Mileage Charts, and Elevation Gain Charts
After 100’s of hours of research, 1000’s of keystrokes, more emails and phone calls than I recall the One of Seven Project’s Colorado Trail Data Sheet and Town List are done. They contain everything you need to plan and execute your ride/ride of the CTR.
DATA SHEET and TOWN LIST DIFFERENCES
The Data Sheet has the most info. It gives the distance, elevation +/-, average grade, max grade, pavement sections, references CTF segments, bike shops, resupply options, key water sources, and has key notes between two POI. Example: A and B, then B to C, and so on.
The Town List gives cumulative distances between POI. Example: A to B, A to C, A to D. The next section would be B to C, B to D, B to E, and so on. The Town List has distance, elevation +/-, resupply options, bike shops, key water sources, and key notes.
The Town List helps with not having to do the math to figure out how far away things are if they’re not the next POI.
