OUTLAST SAN ANTONIO

Saturday, December 12, 2026San Antonio, TX18 Miles

OUTLAST is a demanding 6-hour trail endurance challenge that tests your pacing, discipline, and mental grit. Runners must complete a 5K loop every hour on the hour, with any remaining time within that hour serving as your only recovery window. If you fail to finish a lap before the next hour begins, you are eliminated from the event. The course features natural trail terrain including dirt, rocks, and roots, requiring participants to be prepared for unpredictable conditions. While the challenge is intense, you can earn tiered rewards like the 'Grit Earned' or 'Survivor' patches, or the premium 'OUTLAST' medal for completing all six laps. Top performers have the opportunity to compete for local titles and qualify for the national championship with a $1,000 prize.
