Outlast Colorado Springs

Outlast Colorado Springs pushes athletes to their limits with a relentless 6-hour trail endurance challenge in Colorado Springs on September 25, 2027, starting at 8 a.m.: run a 5K loop (3.1 miles) every hour, on the hour, over technical terrain, for a potential total of around 18 miles (29 km).

Each lap must be completed in under 60 minutes. Finishing early leaves time to recover, refuel and plan your strategy, but going over the time limit means elimination. The course winds along rugged dirt trails strewn with rocks, roots and climbs that test both footing and mental toughness. Discipline and pacing are essential, because only the athletes with the best cumulative times over the six laps win their category and secure a spot at the Outlast championship.
