About this race

Outlast Seattle is a 6-hour trail endurance challenge. Complete a 5K every hour, on the hour. The course is trail-based, with natural terrain, elevation, and unpredictable conditions, often featuring dirt, rocks, and roots. If you miss a lap, you’re out. Finishing all six rounds earns a Premium OUTLAST medal; 4 or 5 laps get a patch.
