Half-Marathon, 5k & 10k Race in Fort Collins Colorado

Online Registration for 2020 will open on July 1, 2019!

The Colorado Marathon is a gorgeous race held annually in Fort Collins, Colorado. This year’s race will take place on May 3, 2020. Registration opens on July 1, 2019 for our 5 races (marathon, half-marathon, 3-person relay, 10k, or 5k). 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.

Certified Boston Qualifier!

The Boston Marathon is the world’s oldest annual marathon. In order to participate, you must first qualify by completing a Boston-qualifying marathon under a certain amount of time. The Colorado Marathon is one of the best marathons to qualify for the Boston Marathon because of our downhill course. The gradual decline in elevation gives runners a fast advantage that not many other Boston qualifier races provide. In fact, each year the Colorado Marathon qualifies 16-18 percent of all participants. That’s pretty fantastic! So, if you’ve always wanted to check Boston off your marathon list, sign up for the 2020 Colorado Marathon now.

Helping the COM Give Back

The Colorado Marathon is in its 19th year. Over the years we have donated over $200,000 to local and national charities and other beneficiaries. We partner with numerous beneficiaries every year in an effort to put on a great event. Our beneficiary groups provide necessary volunteers and other resources required to pull off an event of this size while earning money for their organization.
