Forbidden Forest 30 Hour Ultra Run

Forbidden Forest 30 Hour Ultra Run takes place in Roosevelt Forest, Stratford, Connecticut, October 11-12, 2025. Runners choose a personal challenge on a 2.23-mile loop that weaves through roots, rocky terrain, and a standout hill dubbed "OMG." Competitors can tackle 26.2M, 50K, 50M, 100K, 100 Miles, or more over a 30-hour period. The intimate field typically numbers 25–50 entrants.

An on-course aid station sits at the pavilion every loop, with ample hydration and food, and swag includes race shirts and non-alcoholic beer. A 100-mile buckle awaits those who complete 45 laps; pacers are allowed after 12 hours, and dogs on leash are welcome. Visit the organization's website for the most recent information.
