  02/26/26 Full Marathon Update: We have less than 20 Charity Fund entries for the full marathon and will probably sell out within a couple of weeks. These entries are the only way to register for the full marathon at this time. Once the Charity Fund entries are sold out, there will be no additional registration for the full marathon.

  02/27/26 Half Marathon Update: The half marathon has sold out of standard entries! We have less than 50 standard entries left. Charity Fund entries are $340 for the half marathon and are the only way to register for the half marathon now. We reserve a limited number of Charity Fund entries where all proceeds go to the charities and non-profits that partner with the race. Once these are sold out, there will be no additional registration for the half marathon.

  Join us for the Colorado Marathon in Fort Collins this May! Our annual event takes place in the stunning Poudre Canyon and the gorgeous natural areas of Fort Collins in Northern Colorado.

  Each year, thousands of runners participate in this incredible event to test their endurance, push themselves to new heights, set new PRs, and race alongside other running enthusiasts who share a passion for health and fitness. Many even run Colorado’s fastest race to qualify for the Boston Marathon! Regardless of why you join us at this momentous event, we’re happy to have you!

  With one of the most scenic downhill courses in the state, four different distances to choose from, and a vibrant community-centric atmosphere, this is one race you don’t want to miss. But be quick! Our event sells out quickly, so register early to save your spot in the race. Keep reading to learn all the details about this thrilling running adventure!

  Note: 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. Once the limited number of Charity Fund entries are sold, the race will be officially sold out and registration for that distance will be closed.

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