About Crested Butte Ultra

Crested Butte is known for having some of the best trails in the country and runners get to experience it all at Crested Butte Ultra! Traversing through the Gunnison National Forest, runners will be amazed at the wide open views!  Single track trails take runners through beautiful mountain meadows and up to stunning mountain ridges. At the lower elevations, stunning wildflowers set against mountain backdrops will greet runners as they work their way up the course.  Fall foliage rivaling New England will distract them from the heart pumping climbs.  Come enjoy a weekend getaway in this quintessential mountain town! Crested Butte Ultra is authorized under special use permit with the Grand Mesa, Uncompahgre, and Gunnison National Forests.
