High Five 100 - Lake City, CO

The High Five 100 is a self-directed 100 Miler held in Lake City, Colorado on August 6, 2027. The route requires starting in Lake City and visiting 24 specified locations that include proof points and checkpoints. Checkpoints are the only locations where crew or a runner's drop bag may be used for aid. Instructions for proof points are disclosed at the pre-challenge meeting the evening before the event.

Runners choose their own route between proof points and checkpoints but must arrive at all points in order and return to Lake City within a 48 hour cutoff to be recognized as a finisher. Organizers estimate the most practical route to be between 90 and 105 miles with over 40,000 ft of elevation gain. The course crosses high alpine terrain in the San Juan Mountains and includes summiting five 14ers and six 13ers.

The event does not charge an entry fee, does not mark a course, does not provide aid stations, and does not award a medal for finishing. Participants are expected to follow wilderness regulations and show respect for the land. Registration opens January 1, 2027. The event was created by local Lake City ultrarunners in 2018. An event website is listed as highfive100.com. Visit the organization's website for the most recent information.
