Hardrock 100 Endurance Race


The Hardrock Hundred Mile Endurance Run is an ultramarathon of 100.5 miles, 33,992 feet of elevation climb, and 33,992 feet of descent for a total elevation change of 67,984 feet. The race is held on a loop course, including 4WD roads, dirt trails, and cross country terrain in Southern Colorado's San Juan Mountain range. 

The run begins and ends in Silverton, Colorado and travels through Telluride and Ouray and crosses 13 major passes in the 12,000 to 13,000 foot (elevation) range. Completion of the event is marked by kissing the Hardrock, a picture of a ram's head painted on a large stone. 

This is a graduate level endurance run. Moutaineering, wilderness survival, and wilderness navigation skills are key. The cut off time for finishing the race is 48 hours. Current course records are held by Kyle Skaggs (23:23) in 2008 and Diana Finkel (27:18) in 2009.

The Hardrock 100 is the centerpiece of the Rocky Mountain Slam, the completion of which requires a finish at the Hardrock race, and three of four other races in the Rocky Mountains (Leadville 100, Bear 100 Mile Endurance Run, Bighorn 100, and the Wasatch Front 100 Mile Endurance Run).
