The Colorado Marathon will be held on May 7, 2023 and the Platte River Half Marathon will take place on April 2, 2023.

The Colorado Marathon is a gorgeous race held annually in Fort Collins, Colorado. Registration for 2023 is now open for our 4 races (marathon, half-marathon, 10k, and 5k). A lot of marathons are certified Boston qualifiers. This 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.

The Platte River Half Marathon has a long tradition in Littleton and Denver, which started in 2005. Come check out this flat, fast course with a post race party at Breckenridge Brewery.
