Experience Running a Scenic Marathon Like No Other

The Poudre Canyon in the Rocky Mountains is a breathtaking landscape that sets the stage for the Colorado Marathon’s full, half, 10k, and 5k courses. Runners are treated to stunning views of the canyon walls and verdant tree-lined slopes rising around them as they wind their way along the banks of the shimmering Cache La Poudre River. The mountain setting makes this race a favorite for the “50 State” runners and others looking for an alternative to another urban marathon.

The crisp mountain air carries the scent of pine and the sound of wildlife, adding to the natural beauty of this incredible setting. Whether you’re an experienced runner or a first-time participant, the natural beauty of the Poudre Canyon will energize and invigorate you every step of the way. So come join us and let the Rocky Mountains inspire you to greatness!

Fort Collins: Where Your Racing Adventure Awaits!

Fort Collins, also known as the “Choice City,” is a true hidden gem nestled in the foothills of Northern Colorado. It’s a city that seamlessly blends community, adventure, and culture to offer its visitors an unforgettable experience. With over 20 breweries, including world-renowned Odell Brewing Co., Fort Collins has established itself as the craft beer capital of Colorado. But it’s not just about the beer — the farm-to-table dining scene is a foodie’s dream.

Historic Downtown Fort Collins, the inspiration for Disney World’s Main Street USA, offers a charming and unique atmosphere that is both quaint and vibrant. With over 300 days of sunshine a year, an average of 65-75 degrees daily high temperature in May, and low humidity, runners are given excellent conditions for the race. What better way to experience all of this than by participating in the Colorado Marathon?

Our Commitment to Sustainability

The Colorado Marathon is proudly environmentally conscious and committed to sustainable racing. We’ve gone completely digital with our registration process to reduce paper waste and promote sustainable practices.

Thank you for helping us protect and maintain the natural beauty of the Poudre Canyon!
