About This Distance

A Western States 100 qualifier from Bend to Sisters. 10,900 ft of gain, 11,400 ft of loss, 12 full aid stations, and a finish on the Sisters School District track. The elevation is front-loaded into the first 100K, so the race that looks friendly on paper will ask real questions of your pacing.

Full crew access, pacer support, drop bags, and hot food at night-time aid stations. 32 hour course limit with a sub-24 hour buckle for athletes chasing that goal.

Course Details

Optional $35 one-way shuttle from the finish in Sisters to the start line on race morning (departs Sisters Middle School at 4:30AM sharp). 8 hours of pre-race trail work or volunteer hours required in 2026.
