50 miles on Colorado's Continental Divide - three climbs, seven creek crossings, 12,000+ feet of gain
Other trail races within 61 miles
The San Juan Solstice 50 is a counter-clockwise loop through the San Juan Mountains of south-central Colorado, starting and finishing in the historic mining town of Lake City. The course climbs from 8,671 feet to a high point of 13,334 feet on the Continental Divide, linking the Alpine Gulch Trail, the ghost town of Carson, and miles of the Colorado Trail and Continental Divide Trail through Colorado's most dramatic high-country terrain. Three major climbs totaling over 12,000 feet of gain are separated by two long exposed ridge sections of 9–10 miles between aid stations. Seven creek crossings in Alpine Gulch guarantee wet feet within the first seven miles. The race benefits the Lake City Volunteer EMTs and graduating seniors at Lake City Community School, and has been run every year since 1995.

Course reaches 13,334 ft on the Continental Divide; substantial time above 12,000 ft. Acclimatization strongly recommended.
Afternoon thunderstorms are a serious and frequent hazard on the exposed Divide sections (miles 21–40). Race rules explicitly permit leaving the marked course to shelter below treeline.
Snow on the Divide is possible even in late June. Runners should carry adequate layers; past editions have seen snow squalls and snowfields on the high-altitude CT/CDT sections.
Temperatures above treeline can drop sharply, especially after late-afternoon storms. Night finishers should carry warm layers.
