Once a race reaches capacity, a limited number of entries are reserved for the "Charity Fund." These entries are double the price and all proceeds go to local charities and non-profits that are involved in the race. Once we hit the Charity Fund entries, this is the only way to register for that distance.

You will be able to register or change races at the expo on Friday or Saturday of race weekend. If a race has reached capacity, there will be no new registration or changes to that distance.


The Colorado Marathon is an environmentally conscious event, thus we will only have online registration in an effort to reduce the environmental impact of paper waste and other resources. Thank you for your support!

Whether you're visiting for a day or a week, Fort Collins offers you plenty of choices for fun. We'll show you where to shop, where to hike, and where to dance. For more information about Fort Collins, Colorado, visit the Fort Collins Web Site.
