Course and race logistics
All courses run mainly on rough gravel roads and resemble a trail run more than a typical road race. Aid stations are spaced about 3 to 5 miles apart; some stations offer limited service with water, gels, electrolytes, and ice, while others offer full service with PB&Js, chips, fruit, drinks, and gels. The event is cup-less; participants must bring their own bottle, bladder, or reusable cup to refill at aid stations. There are no restrooms or porta-potties on the course, and runners are asked to pack out used toilet paper or wipes. Parking is allowed along Owens Road near the start/finish; do not park on Highway 397 or drive offroad. The organizer notes footwear should be appropriate for gravel roads. Registration fees increase on April 1 and August 1, with some in-person registration available. Visit the organization's website for the most recent information.
