Hardrock 100 Endurance Run:

A Testament to Human Resilience

The Hardrock 100 Endurance Run is not just a race.

It's an homage to the ruggedness of the San Juan Mountains and the human spirit.

Set in the heart of Colorado, it presents one of the most challenging terrains in ultrarunning, known for its extreme conditions, high elevation, and technical trails.

Origins and Evolution

The Hardrock 100 was born out of a love for the San Juan Mountains and the mining history of the region. First run in 1992, the event was conceived to link the historic mining towns of Silverton, Telluride, Ouray, and Lake City. It has since become a cornerstone in the ultrarunning community, revered for its difficulty and beauty. The race is traditionally held in July, testing runners with unpredictable mountain weather ranging from scorching sun to snowstorms.

Route and Challenges

The course is a 100-mile loop with 33,000 feet of cumulative elevation gain and loss, peaking at 14,048 feet at Handies Peak. Runners navigate through rugged terrains, cross streams, and scale steep scree fields, embodying the race's motto, "Wild and Tough." The altitude, combined with the technical nature of the trail, requires not only physical endurance but also significant mountain running skills and navigation competence.
