All courses begin and end in North Bend State Park. The altitude of the area ranges from 500 ft to 1300feet above sea level. The first portion of the race is along winding paved roads, and returns back to the park along the NorthBend Rail Trail, which is similar to a dirt/gravel road that is very flat and straight.
