About This Race

The 8-hour challenge offers a substantial introduction to timed endurance running without crossing into ultra territory. Most runners will complete multiple loops on the rolling terrain, making this duration ideal for those stepping up from traditional trail races or testing their endurance ceiling. The timeframe allows for strategic pacing and nutrition practice while maintaining a clear finish line.

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.
