Colorado Marathon : Fort Collins, Colorado
The Colorado Marathon is an annual road running event held in Fort Collins, Colorado, with courses routed through the Poudre Canyon in the Rocky Mountains. The 2026 edition is scheduled for May 3, 2026 and lists Fort Collins as the event location.
The event program includes multiple distances:
- Full Marathon
- Half Marathon
- 10K
- 5K
Courses use scenic sections of the Poudre Canyon and natural areas of Fort Collins, with portions running along the Cache La Poudre River. The full marathon is described as a downhill course that many runners use to attempt Boston Marathon qualification. The race has been designated the Colorado RRCA State Marathon Championship for 2023 through 2026.
Event operations include an expo on the Friday and Saturday of race weekend where participants can register or change distances, except when a distance has reached capacity. When a race fills, a limited number of Charity Fund entries may remain; those entries are priced higher and the proceeds support local charities. The organizers report sustainability measures such as digital registration, elimination of paper goody bag items, and efforts to reduce single use paper at the event.
