Portland Marathon

Portland Marathon course route

The Portland Marathon is a city loop starting and finishing at Waterfront Park, crossing the Willamette River, passing Powell's Books, and following the Springwater Corridor. The Springwater and waterfront sections are the easiest because they stay relatively flat and shaded, while the bridge approaches and subtle inner eastside rollers are tougher; spectators gather at Waterfront Park, along the bridge crossings, and on the Springwater Corridor.
