High Five 100 - Lake City, CO
The High Five 100 is a self guided point to point challenge based in Lake City, Colorado. The event is presented as a 100 Miler that requires visiting 24 specified locations made up of proof points and checkpoints. It was created in 2018 by local ultra runners.
Participants choose their own route between proof points and checkpoints but must visit all points in the prescribed order. Checkpoints are the only locations where crew or the participant's drop bag may provide aid. Instructions for proof points are disclosed at the pre challenge meeting the evening before the event.
The most practical route is estimated at 90 to 105 miles with over 40,000 feet of elevation gain. For recognition of finishing the challenge, participants must return to Lake City within a 48 hour cutoff. Completing the route typically involves summiting five 14,000 foot peaks and six 13,000 foot peaks and traversing rugged terrain in the San Juan Mountains.
Organizers do not charge an entry fee. The course is not marked, there are no aid stations, and finishers do not receive a medal. Registration was closed on January 31, 2026. Visit the organization's website for the most recent information.
