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.
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.
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.
