Hardrock 100 Endurance Run

The Hardrock Hundred Endurance Run returns on July 9, 2027, with an epic 100-mile loop through the rugged backcountry of Colorado's San Juan Mountains. This challenging course offers runners breathtaking vistas and a chance to explore historic mining towns like Silverton, Ouray, Telluride, Lake City, and Ophir.
With an elevation gain totaling around 33,000 feet and average elevations near tree line at approximately 11,186 feet, the route features several peaks over 14,000 feet, including Handies Peak. The terrain is both varied and demanding, with stretches of rocky trails winding through alpine meadows and dense forests.
Participants must register using their exact qualifier results name to ensure accuracy in the lottery process scheduled for December 5, 2026. Runners are encouraged to review their volunteer history carefully as it can impact their entry chances into the race. Each year's event is a testament to endurance runners' dedication and passion for conquering some of Colorado’s most challenging terrain.
Beyond the physical challenge, the Hardrock Hundred also supports local communities through donations to scholarship funds benefiting students from the four anchor towns, trail maintenance initiatives, and mountain safety efforts. These contributions enhance wilderness experiences while supporting responsible outdoor education and search-and-rescue operations in the region.
The race not only celebrates athletic achievement but also fosters a sense of community among runners, volunteers, and local supporters who come together to honor the spirit of exploration and perseverance embodied by the Hardrock Hundred Endurance Run.
