Course and logistics
All courses run on gravel roads on and around Jump off Joe Mountain. The half and full routes reach the mountain summit and offer views over the Tri-Cities and into Oregon. The course is not certified; measured distance and elevation may vary slightly. The 10k is out-and-back with an aid station at the turnaround. The half has three aid stations with one passed twice. The marathon has six aid stations with two passed twice. Aid stations are spaced about 3 to 5 miles apart. Some stations provide limited service (water, gels, electrolytes, ice) and others full service (PB&Js, chips, fruit, drinks). This is a cup-less race; participants must bring their own bottle, bladder, or reusable cup. There are no restrooms on the course. The course is not closed to traffic and runs on private-property-adjacent roads, so participants must stay on the roads and watch for vehicles. Appropriate footwear for rough gravel is recommended.
