High Five 100 - Lake City, CO
The High Five 100 is a self-directed 100 mile foot challenge held in Lake City, Colorado on August 7, 2026. The event was created in 2018 by local ultra runners and requires competitors to visit 24 specified locations in sequence, made up of proof points and checkpoints.
Checkpoints are the only locations where a runner may receive aid from a crew or a provided drop bag. Proof points serve to verify that a runner reached a specific location; instructions for proof points are given at the pre-challenge meeting the evening before the event. Runners choose their own route between points but must arrive at all points in order and return to Lake City within a 48 hour cutoff to be recognized as finishing.
The practical route is estimated between 90 and 105 miles with more than 40,000 feet of elevation gain. The route traverses rugged terrain in the San Juan Mountains and includes summiting five 14ers and six 13ers. Participants are expected to follow wilderness regulations and show respect for the land.
The event does not use a marked course, does not provide aid stations, does not charge an entry fee, and does not award a finishing medal. Registration for the 2026 event closed on January 31, 2026. Visit the organization's website for the most recent information.
