The Oregon half marathons we recommend as the best for beginners most frequently are:

The Shamrock Run Portland: Portland’s longest running St. Patrick’s Day tradition with over 25,000 runners participating across all distances. The massive crowds make this a festive environment and the finisher’s party has a green beer garden and live music.
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.
Columbia Gorge Half Marathon: A 7-hour cut off time with beautiful fall foliage alongside the Columbia River.
