About the Colorado Marathon

The Colorado Marathon is built for runners who want a scenic downhill road race without giving up the feel of a serious performance event. The canyon setting gives it real visual character, but its reputation is tied just as much to pace goals.

Course

The marathon drops out of Poudre Canyon toward Fort Collins, so the day feels different from a flat urban race even when the splits are moving. The point-to-point setup and long descending profile make it attractive to runners looking for a fast road marathon with real mountain-country scenery.

Race-day weather

The canyon start can feel cool, especially before the sun reaches the road fully. As the course drops and the morning opens up, the air usually warms and dries out, so effort management still matters even on a fast profile.
