High Five 100 - Lake City, CO

High Five 100 : Lake City, CO

The High Five 100 is a self navigated point to point endurance challenge that begins and ends in Lake City, Colorado. The event directs runners to visit 24 specified locations made up of proof points and checkpoints. Participants may choose their own route between these points but must arrive at all points in the prescribed order.

Checkpoints are the only places where a runner may receive aid from a crew or from a preplaced drop bag. Proof point procedures are explained at a pre challenge meeting held the evening before the event. Finish recognition requires returning to Lake City within a 48 hour cutoff.

The most practical route is estimated at 90 to 105 miles with over 40,000 ft of elevation gain. Completing the course involves summiting five 14ers and six 13ers and traveling across high mountain terrain in the San Juan Mountains. The organizers expect participants to follow wilderness regulations and to respect the land.

The event does not charge an entry fee, does not mark a course, and does not provide aid stations. No medal is issued for finishing. The race concept originated in 2018 when local ultra runners in Lake City developed the challenge. Registration for the 2026 edition closed on January 31, 2026.
