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.
