Welcome to the Colorado Marathon, one of the most stunning races in the country! This annual marathon is held in the verdant Poudre Canyon, nestled in the picturesque Rocky Mountains, just outside of the beautiful city of Fort Collins.

We’re thrilled to announce that registration for our upcoming 2026 event open on July 1st for all four races, including the full marathon, half-marathon, 10k, and 5k. This event, designated as the RRCA Colorado State Marathon Championship in 2023, 2024, and 2025, promises an unforgettable experience for runners of all ages, levels, and abilities. Register with confidence! Racers can change to a shorter distance to match their current fitness and ability. Join us on Sunday, May 3, 2026, for a day of exhilarating running, breathtaking scenery, and the opportunity to push yourself to new heights. But be quick!
