Course and aid

All courses use double-track and single-track trails with zero pavement. There will be one main aid station at the Pisgah Point Group Camping Area offering water, electrolyte drink, assorted ultra-style snacks, and drop bag access. Drop bags are stored at the start/finish aid station and are available each time a participant returns there.

12-Hour format

The 12-Hour event uses a loop-based system determined by colored balls drawn from a bucket; each color corresponds to a marked loop. Balls include Green, Blue, Orange, Red, Purple, and Black. Pulling a black ball gives the runner either a short time-out or a task from the task master; completing the task can earn an override ticket for later use. Runners' results are the total miles recorded while they participate. Runners who complete at least one loop are listed as finishers.

Logistics and awards

The 10k, Half Marathon, and Marathon have an extended cutoff time. Camping is allowed on site with limited spaces and restrictions on vehicle types; only registered runners may camp with the event. Finisher awards are given to those who complete the 10k, Half Marathon, or at least one 12-Hour loop. No awards will be mailed. Visit the organization's website for the most recent information.
