OUTLAST SEATTLE – Sammamish, WA 2026

What Is OUTLAST? 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.
