This year there will be a mandatory $50 donation to the Colorado Trail Foundation trail crew program to get on the list. More on that as we get closer.

The Colorado Trail Race is a self supported bike ride. The specific rules for the CTR are here: https://jwookieone.com/colorado-trail-race/colorado-trail-race-rules/ Know the rules it is the riders responsibility! Ther rules are there to keep it equal among riders, maintain the ethos of self supported racing and minimize impact to the trail. We call it a race, but really is an adventure! Be smart, be safe, be responsible for yourself, you are on your own out there and you should be able to deal with mechanicals. injuries, etc.

The CTR wants to stress that we are guests on this trail and on the land we traverse. CTR racers do not have any more clout on the trail than anyone else. There are hundreds of other trail users doing a similar thing and they are all equally special and awesome, so don’t make your race take away from some else’s experience out there! Practice yielding to others and leaving no trace, “racing” does not excuse you from proper behavior on the trail.

A quick bit about rules and such. If you do not want to strictly follow the CTR rules, or the CTR course, or want to take your time on the CT, please consider touring it or simply riding it on your own. Riding the Colorado Trail is just as amazing of an experience as racing it and allows many riders the flexibility to perhaps have a better time. To be clear, there are lots of ways to experience the CT outside of the race and all the rules, start time, etc, that go along with it. Want to take a film crew and make a movie, or have family and friends meet you at trailheads, go for it, but not as part of the CTR. Want to skip a few sections, why not, but don’t compare yourself to those who ride 100% of the course. There are plenty of opportunities and ways to ride the CT and the CTR is just one of them and is focused on a self supported, go as fast as you can style on the prescribed course.

Course is most likely the same as past years, will have an updated GPX at some point, but older files should be fine for research purposes.

Lots of info out there, do your research!!!
