Course and race services

The course uses a cloverleaf design built from a larger 25k loop that contains three sub-loops (red, green, blue). Trails are primarily single track with rolling terrain and no single climb or descent over 400 feet. The red loop passes a waterfall and basalt outcrops, the green loop passes another lake and canyon-like terrain, and the blue loop drops into the Columbia River Gorge and runs along the river before climbing back to the finish.

A single central aid station is used repeatedly during the races. Participants must carry their own hydration system capable of holding at least 16 oz. of fluid; the aid stations are cupless. Drop bags are stored at the start/finish and are accessible after each loop. Pacers are allowed only in the 50 Mile race. Parking and packet pick-up are at the Bishop Recreation Area. Refunds and deferrals are not offered. Visit the organization's website for the most recent information.
