About This Race

The Mosquito Hill Endurance Run offers a straightforward time-based challenge on Florida's rolling terrain, where runners accumulate distance over 3, 6, or 12-hour periods on a 3.4-mile loop course. Set in Brooksville, this grassroots event emphasizes simplicity and community over flash, with manual timing and a single well-stocked aid station at the start/finish area. The race's unique directional change on each loop keeps the challenge fresh, while the relatively runnable terrain with minimal technical obstacles makes it accessible to runners testing their endurance limits for the first time. With approximately 400 feet of elevation gain per loop, the course provides steady climbing without overwhelming vertical challenge. The event's cup-less policy and bring-your-own-nutrition approach reflects a growing trend toward environmentally conscious racing and runner self-sufficiency. Pacers are permitted for 12-hour participants starting at noon, and the race allows strategic mini-loops of half a mile for time-pressed runners, though organizers emphasize honesty in this system. The long history of results dating back to 2016 demonstrates the event's established place in Florida's trail running calendar.

The 3.4-mile loop course winds through Brooksville's characteristic rolling hills, featuring approximately 400 feet of elevation gain per circuit. Runners reverse direction with each completed loop, providing variety in perspectives and muscle engagement patterns throughout the day. The terrain is described as highly runnable with minimal rocks and roots, making it suitable for runners focused on accumulating distance rather than navigating technical challenges.

The single aid station at the start/finish line serves as both logistical hub and social center, where runners can access cold beverages, snacks, and watermelon. The course marking system uses flags and cones, and manual timing requires runners to ensure volunteers record each completed lap.
