"The Steve Prefontaine Memorial Jogging trail is located in Alton Baker Park, and is accessible from parking lots at three trailhead entrances at each of the three main loops. There are two footbridges, providing access from the University of Oregon campus, located just across the Willamette River. From campus, the Center Loop can be accessed via the Autzen Footbridge (south of Autzen Stadium, half a block north of Franklin and Agate Streets), and to the southeastern Big Loop via the Knickerbocker Footbridge (near Franklin and Riverview Streets)."
"Steve Prefontaine, or "Pre," was impressed with the style and terrain of European cross country running courses while competing overseas. Upon return from Europe, he suggested to local officials about building a running trail through Eugene's Alton Baker Park. Lane County worked with the Oregon Track Club and University of Oregon track coach Bill Bowerman to design and build Pre's Trail. Within four months of Pre's death in an auto accident in 1975, the new trail served as venue to a memorial race of approximately five hundred participants in his honor." (Source - Wikipedia)
