Eugene Marathon: We love the course from Eugene to Springfield, alongside the Willamette River, and on the same roads that have been run for over 50 years. Most notable – the finish at historic Hayward Field, the University of Oregon track, home to iconic runners like Steve Prefontaine and Bill Bowerman of Nike.
