Eugene sits in the Willamette Valley of western Oregon, a university city known as Track Town USA. The University of Oregon gives the city its campus and its running heritage, and Hayward Field, the historic track stadium, has hosted Olympic trials and world championships. The Willamette River runs through town with paths for walking, running, and biking, and Skinner Butte rises above downtown with views across the valley. The Saturday Market, one of the oldest weekly open-air markets in the country, fills a downtown park with crafts, food, and music.
