This out-and-back course is fast and flat. Starting at SW Pine and Naito, 8K runners will head north on Naito, passing the Burnside, Steel, Broadway, and Fremont Bridges as they transition onto NW Front Avenue. Participants continue along the Willamette River before reaching the turn around just south of NW 26th. The 8K finishes at SW Stark and Naito, just across from the Morrison Bridge and a few steps from the finish line festival.
