OUTLAST CHICAGO : October 24–25, 2026
OUTLAST CHICAGO is a two-day, six-hour trail endurance challenge held at Deer Grove East in Palatine, IL. Each event runs as a sequence of six repeated laps: participants must complete a 5K lap every hour, on the hour. Each lap must be finished within that hour to remain in the event; runners who miss a lap are eliminated. Those who finish all six laps earn the event medal.
The course is trail-based and may include dirt, rocks, roots, elevation changes, and sometimes pavement or gravel. The format gives short recovery windows between laps for refueling and rest. Aid is available at basecamp with water, basic hydration, and snacks; this is a cupless event, so participants should bring their own bottle or hydration system. Participants receive a premium OUTLAST tee. Completing four laps earns a “Grit Earned” patch, five laps a “Survivor” patch, and six laps the premium OUTLAST medal.
Winners are determined by the fastest combined times across the six 5K laps. Top finishers are added to a national leaderboard; the fastest runner across OUTLAST 6-hour events is eligible for a national prize. City champions may qualify for a championship event with additional prize places. The event allows personal aid setups and tent space at the loop start.
