Mosquito Hill Endurance Run

The Mosquito Hill Endurance Run is an annual trail running event held at Mosquito Hill Nature Center in New London, Wisconsin. Participants run or walk on a 3.4-mile loop trail featuring wetlands, prairies, forests, and a climb to the top of Mosquito Hill, with about 400 feet of elevation gain per loop. The course is wide, non-technical, and suitable for all skill levels.

The event offers timed options of 3, 6, and 12 hours, allowing runners to cover as many miles as they can, plus a flexible 5k fun run. Proceeds support the nature center, and the race is volunteer-run. Amenities include aid stations, awards for top finishers, and finisher medals.
