Mosquito Hill Endurance Run (October 23, 2027)
The Mosquito Hill Endurance Run takes place at Mosquito Hill Nature Center in New London, WI, at address N3880 Rogers Road. The event uses a marked trail loop of approximately 3.3 miles that passes through wetlands, prairies, and forest and climbs to the top of Mosquito Hill. Each loop has roughly 400 feet of elevation gain. The route is described as non-technical, wide, and generally runnable with few rocks and roots. Participants switch running direction on each loop.
The event offers these options:
- 12 hour individual
- 6 hour individual
- 3 hour individual
- 2-4 person relay team
Timing is manual; participants are responsible for making sure volunteers see and count each lap. There is one fully stocked aid station at the start/finish area; cold soda, water, chips, cookies, and watermelon are listed as available after the race. The event is cup-less for cold drinks so participants are asked to bring a reusable cup; hot cups are available for soup.
Packets are distributed at the start/finish area and there is no same-day registration once online registration closes. Portable toilets will be available and the indoor bathroom will be open. Tents and tables are allowed near the start/finish; overnight camping is not allowed. The event is organized entirely by volunteers and 100% of proceeds support the park through Friends of Mosquito Hill Nature Center, a 501c3. Rules list offenses that result in disqualification, including alcohol use, bringing pets, littering, intentional course cutting, and rude behavior toward volunteers.
