The Trail Running Challenge
Outlast is a trail endurance challenge where you complete one 5K every hour for 6, 12 or 24 hours. Each lap must be finished within the hour to stay in the event.
Complete all the rounds and you Outlast.
Each loop starts at the top of the hour.
Miss your lap, and your race is over.
Recover, refuel, and get back to the line.
Dirt, rocks, roots, and real elevation change.
You don't need to be fast. You need to show up.
Find A Race
You need to be consistent. One 5K every hour for 6, 12, or 24 hours is a hard thing, and finishing it means something.
There's no faking this one. The medal, the leaderboard ranking - they're proof. You either showed up the whole time or you didn't.
Bring your crew. Set up a tent. Cheer each other through every hour. Outlast is better when you’re with friends.
