About This Race
The flagship 24-hour challenge represents the full dawn-to-dusk experience, requiring runners to navigate daylight transitions, night running, and extended loop repetition. Participants face the mental and physical demands of ultra-endurance while the gentle elevation profile keeps the focus on time management and pacing strategy. This duration attracts both seasoned ultrarunners and ambitious newcomers ready for their first 24-hour attempt.
The course consists of a 4.5-mile loop that includes a scenic section along the lake at Camp Sinawa. The route offers minimal elevation challenge with only 330 feet of gain per loop, making it well-suited for runners focused on distance accumulation rather than technical terrain navigation. The loop format allows for excellent spectator and crew access while providing consistent aid station support.
