About This Race
Doubling the time commitment, the 12-hour option transforms the same challenging loop into an endurance test that pushes both physical and mental boundaries. Runners navigate the course's 876-foot elevation variations repeatedly, with success depending heavily on nutrition strategy, pacing discipline, and the ability to maintain form through fatigue. This extended format appeals to runners seeking to explore their limits without the pressure of a fixed distance target.
The course consists of a 6-mile loop starting from the Big River valley and climbing to the valley's edge with 875 feet of elevation gain per loop. The route is primarily singletrack trail, offering technical terrain that demands attention and respect. Two well-positioned aid stations provide comprehensive support throughout each loop.
Runners in the timed events complete as many loops as possible within their time limit, while distance event participants complete predetermined loop counts. The loop format allows runners to gauge their progress and adjust strategy, while the sustained climbing on each circuit creates a cumulative challenge that tests both physical and mental endurance.
