Tough Mudder - Toughest Mudder Colorado

Toughest Mudder Colorado, held at Fort Carson, is a grueling 12-hour overnight endurance event scheduled for September 27, 2025. Participants tackle a challenging 5K course filled with extreme obstacles such as the greased 13-foot Everest quarterpipe, the barbed wire Kiss of Mud, and the water-filled Cage Crawl. The event offers individual and team relay formats with age group categories and awards.

Despite the overnight timing, the atmosphere is supportive and well-equipped, featuring a dedicated pit area with amenities like hot water heaters and snacks.
