The San Juan Solstice 50 Mile, taking place on June 20, 2026, in Lake City, CO, is a quintessential mountain ultra that combines breathtaking San Juan Mountains scenery with an undeniably rigorous challenge. This 50-mile single-loop course boasts altitudes ranging from 8,671 feet to a staggering 13,334 feet, accumulating between 12,000 and 12,800 feet of elevation gain. Runners navigate a course that is 95% rugged trail and some jeep roads, experiencing everything from multiple creek crossings in Alpine Gulch to vast stretches along the Continental Divide. Known for its "brutal but awesome" nature and considered by many to be among the toughest 50-milers, the race promises huge views and a deep dive into high alpine bliss. Typical race day conditions in late June bring highs around 71°F and lows around 35°F, with a minimal 3% chance of precipitation, though runners should be prepared for diverse mountain weather, including potential thunderstorms at altitude.

The race begins and concludes at the welcoming Town Park in Lake City, offering a genuine small-town ultra-running atmosphere that runners consistently praise. Along the challenging route, participants will find seven aid stations and two additional snack stops. Key aid stations at Williams Creek (mile 15.7), Carson (mile 21), and Slumgullion (mile 40) are fully stocked and provide crucial drop bag and crew access. However, be advised of significant 9-10 mile stretches between aid on the Continental Divide, necessitating smart hydration and nutrition strategies. First run in 1995 as the Lake City 50, this historic event now operates as a non-profit benefiting Lake City's volunteer EMTs and local high school scholarships, cementing its deep roots and positive impact on the community.

The San Juan Solstice 50 Mile is renowned for its "flawless management" and its "no whining" ethos, attracting experienced trail runners comfortable with high-mountain environments.
