The San Juan Softie 100, scheduled for August 14, 2026, in Durango, Colorado, challenges ultra-runners to a demanding yet awe-inspiring 100-mile journey through the majestic San Juan Mountains. Beginning and concluding just north of Durango, this ultramarathon immerses participants in spectacular alpine scenery. The course boasts an average running elevation of nearly 10,000 feet and features over 20,000 feet of vertical gain, characterized by steep ascents and descents across rugged terrain. While earning the affectionate moniker "the softest 100 miler in the San Juans" when compared to other formidable regional races, its significant vertical and exposure above treeline ensure a truly formidable test, as evidenced by a considerable DNF rate during its inaugural 2024 running.

Runners will navigate largely runnable trails, commencing with a climb up the Purgatory ski slopes before descending into vibrant wildflower fields and tracing sections of the iconic Colorado Trail. The route offers breathtaking vistas of Engineer Mountain, the Wilson group of 14ers, and Lizard Head, leading to exposed ridge lines around Elliot Mountain at an impressive 12,000 feet. Aid stations, strategically placed every 8 to 10 miles, are well-stocked with vital supplies, including Tailwind and GU, with several locations offering crew access. Pacers are permitted from mile 45.5 to provide support through the demanding later stages of the race. Typical race day conditions in mid-August present highs around 85°F and lows near 52°F, with a minimal 5% chance of precipitation. With a generous 38-hour cutoff and praised volunteer support, the San Juan Softie 100 promises an unforgettable mountain ultra experience, culminating in a festive finish line with burgers, beers, and a well-deserved buckle.
