Course and support

The main course uses a cloverleaf design built from a larger 25K loop that contains three sub-loops called red, green and blue. Trails are primarily single track. Route features include basalt rock outcroppings, a waterfall, shoreline running near desert lakes and a section that drops into the Columbia River Gorge. The course description notes rolling terrain with no single climb or descent greater than 400 feet.

Runners pass a single central aid station multiple times during races. Aid stations will be cupless and runners are required to carry a hydration system capable of holding a minimum of 16 oz. Drop bags are available at the start/finish and are accessible after each loop. Search and rescue support is provided on course.
