Mosquito Hill Endurance Run

The Mosquito Hill Endurance Run, taking place on October 25, 2025, at the Mosquito Hill Nature Center in New London, WI, offers a unique trail running experience for participants of all skill levels. Runners can choose from 3, 6, or 12-hour timed events, as well as a casual 5k that can be started at any time between 9 AM and 5:30 PM. The course features a 3.4-mile loop through diverse landscapes, including wetlands and forests, with minimal technical challenges. All proceeds support the nature center, and the event is organized entirely by volunteers. Participants are encouraged to bring reusable cups and enjoy post-race refreshments.
