Runners follow an out-and-back loop course for both the marathon and the half marathon through the wilderness of Sauvie Island, which lies just to the northwest of Portland. From the starting line at the Sauvie Island Pumpkin Patch, the course takes runners on a clockwise loop around the island — one time around for those running the half, and two loops around for those running the 26.2-mile race.
Note: The course map above provides the approximate route for the race. Though every effort has been made to ensure its accuracy, changes are sometimes made to race routes due to weather conditions, road closures or other circumstances that can require a course to be changed.
