OUTLAST DENVER 2026

The race.

OUTLAST Denver is a 6-hour trail endurance event held on October 3, 2026, in Littleton, Colorado. Runners complete one 5-kilometer loop on trail terrain each hour for up to six rounds; each lap must be finished within its hour window to remain eligible for the next round. Participants who complete four laps earn a "Grit Earned" patch, five laps earn a "Survivor" patch, and all six laps earn the premium OUTLAST medal. All participants receive an OUTLAST tech shirt. Water, hydration, and snacks are available at basecamp between rounds. Runners are ranked on a national leaderboard based on combined time across all six completed laps, with the fastest male and female finishers from each city advancing to the OUTLAST Championship in December 2027.
