OUTLAST INDIANAPOLIS

OUTLAST Indianapolis is a trail endurance event held on 10/17/2026 in Columbus, IN (3989 S 525 E). The format asks participants to complete a 5K lap every hour, on the hour. Each lap must be finished within that hour to remain in the event; finishing early allows rest until the next round, and missing a lap ends a participant’s run.

Two timed formats are offered: a six-hour challenge and a twelve-hour ultra challenge. Each 5K lap is timed individually, and combined times for all completed laps determine local winners and leaderboard placement. Top male and female finishers in each event are determined by the fastest combined 5K times.

Courses are on trail terrain, including dirt, rocks, roots, elevation, and occasionally pavement or gravel. There is time between laps to recover, refuel, and prepare for the next lap. Aid is available at the basecamp/loop start with water, basic hydration, and snacks; this is a cupless event so participants should bring their own bottle or hydration system. Participants may set up a tent or personal aid station.

Awards and recognition include patches for partial completion, premium medals for finishing all laps in the chosen race, a premium OUTLAST tee for all participants, world leaderboard rankings, and cash prizes and championship qualification opportunities for top finishers.
