Mt. Sneffels Half Marathon and 10K

Lace up your shoes for the Mt. Sneffels Half Marathon and 10K on August 15, 2026, and experience the unparalleled beauty of Ouray and Ridgway, Colorado, often called the "Switzerland of America." This long-standing event, celebrating over 25 years, offers runners a unique challenge amidst breathtaking mountain scenery, with proceeds benefiting the Mt. Sneffels Education Foundation to support local students.

The Half Marathon presents a stunning point-to-point journey, typically starting in Ouray at approximately 7,700-7,800 feet elevation and descending to Ridgway at around 7,000 feet. While offering an overall downhill profile, runners should be prepared for some challenging hilly sections and significant elevation changes. The 10K is an out-and-back course, beginning and ending at Ridgway's Frontier Park. Both races primarily traverse scenic county roads, with 90-99% of the surface being packed dirt or gravel, providing a softer impact and an authentic mountain running experience. Along the route, you'll be treated to spectacular views of towering peaks like Mt. Sneffels (14,101 ft), Mt. Abrams (12,800 ft), and Whitehouse (14,000 ft), as you follow the historic railroad route through ranch lands and mining areas. Typical race day conditions in mid-August feature pleasant highs around 77°F and lows around 52°F, with an average 11% chance of precipitation.

Runners consistently praise the Mt. Sneffels race for its challenging yet rewarding courses and the incredible solitude found amidst the gorgeous surroundings. Be mindful that this is a cupless race, so bringing your own hydration container is essential. The half marathon kicks off in Ouray's Felin Park, while the 10K starts at Ridgway's Athletic Park/Frontier Field. Post-race shuttles are available to transport half marathoners back to Ouray.
