About this race
The San Juan Solstice 50 begins and ends at Lake City Town Park in Lake City, Colorado. It sends runners into the high San Juan Mountains for 50 miles around the summer solstice. This is a mountain ultramarathon, not a casual trail race: entrants must be adults, must have completed a trail ultra previously, and are expected to be comfortable in high-country terrain. The field can fill by lottery, with hundreds of runners accepted and hundreds more waiting for a spot.
The race started as the Lake City 50 and had to shorten its initial route when snowfields blocked the Continental Divide. Its calendar has shifted because July brings tourist crowds to Lake City and lightning danger on the Divide, while earlier summer dates can mean deep snow and rough creek crossings in Alpine Gulch. The event later transferred to the Lake City community and became a benefit for local EMTs. Runners should anticipate genuine mountain challenges: snowfields have required hand-shoveled tracks, creek crossings have left participants soaked to the neck, and live trackers are mandatory so the race can monitor everyone across remote terrain.
