May 7, 2023 ONLINE REGISTRATION FOR 2023 IS NOW OPEN.
The Colorado Marathon is a gorgeous race held annually in Fort Collins, Colorado. The 2023 will take place on May 7, 2023. Registration for 2023 is now open for our 4 races (marathon, half-marathon, 10k, and 5k). Once online registration closes, you will only be able to register at the expo on Friday or Saturday. A lot of marathons are certified Boston qualifiers. Our course happens to be one of the most successful at providing qualifying performances. 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!
The Colorado Marathon has qualified roughly 16-18% of all Boston qualifiers entrants each year.
