OUTLAST Indianapolis is a trail endurance event held in Columbus, IN (3989 S 525 E, 47203). The event offers two timed formats where participants run a 5K loop every hour and must complete each lap within the hour to continue.

Each format:

  • 6 Hour Challenge: 18 Miles
  • Outlast ULTRA 12 Hour Challenge: 36 Miles

The course is trail based with natural terrain, elevation changes, and variable conditions. Runners who finish a lap early rest until the next hour; missing a lap ends a participant’s attempt. Timing is done per 5K lap and combined times determine local placings and leaderboard position.

Support at the loop start includes water, basic hydration, and snacks at a basecamp aid station. The event is cupless, so participants should bring their own bottle or hydration system. Tents and personal aid setups are permitted at the site.

Rewards are tiered by laps completed: patches for four and five laps, a premium OUTLAST 6-inch medal for six laps, and a premium 12-inch OUTLAST medal for twelve laps. All participants receive a premium OUTLAST tee. Top male and female combined times earn city awards, entries on a national leaderboard, and a chance at national and championship prize money.
