San Juan Solstice 50 Mile

The San Juan Solstice 50 Mile is a challenging ultramarathon held annually near Lake City, Colorado, typically around the summer solstice in June. Established in 1995, the race covers a 50-mile course through high mountain terrain, including snowfields and creek crossings along the Continental Divide. The event supports the Lake City EMTs and features a rugged course with aid stations and cutoff times to ensure safety.

With a participant cap of 300 runners and a waitlist, the race requires prior ultra trail experience and comfort in alpine conditions. Live tracking is mandatory, and the race atmosphere combines community support with the demanding beauty of the San Juan Mountains. Visit the organization's website for the most recent information.
