Embark on an unforgettable journey through the heart of the San Juan Mountains at the Ouray 100 Mile Endurance Run, taking place on July 17, 2026, in Ouray, Colorado. Known as the "Switzerland of America," Ouray sets the stage for what is widely considered one of the world's most difficult 100-mile races, starting and finishing at the picturesque Fellin Park, mere yards from the town's renowned hot springs. This challenging course demands respect, featuring an astounding 41,862 feet of elevation gain over approximately 102 miles, with 14 major climbs, including the relentless 5,000-foot ascent to the iconic Bridge of Heaven before the final descent. Runners will traverse rugged, unpaved trails, jeep roads, and technical terrain with substantial rocks and roots, pushing through elevations often exceeding 10,000 feet and reaching a high point of 13,340 feet at Fort Peabody.

The Ouray 100 is celebrated for its "low-frills, old school" ultrarunning ethos, focusing squarely on the monumental challenge and breathtaking scenery of the San Juan Wilderness. Participants are treated to jaw-dropping mountain views, alpine lakes, and historic mining ruins throughout their multi-day endeavor. Aid stations, lauded by runners for their supportive volunteers, offer crucial respite along the demanding route. Typical race day conditions in mid-July bring highs around 80°F and lows around 53°F, with a 13% chance of precipitation, though runners should be prepared for potential severe weather, including hail and lightning, at higher elevations.

More than just a race, the Ouray 100 is an immersive experience where the true competition is "us against the mountain." Completing this epic 100-mile distance not only earns a coveted "bad@$$ buckle" but also a profound sense of accomplishment, cementing your place among those who dare mighty things.
