Outlast Denver

October 3 @ 8:00 AM

OUTLAST is a 6-hour trail endurance challenge where runners complete a 5K every hour, on the hour. Each lap must be finished within the hour to stay in the event. If you finish early, you rest until the next round. Miss a lap, and you’re out.

Complete all six rounds, and you OUTLAST.

This isn’t just about speed — it’s about pacing, discipline, and mental grit. Whether you’re trying to survive all six or win your division, the challenge is the same: show up each hour, push your limits, and stay in it.

Each course is trail-based, with natural terrain, elevation, and unpredictable conditions. You’ll have time between rounds to recover, refuel, and refocus — but not much.
