Umatilla Rim Ripper
The Umatilla Rim Ripper is a trail running event near Tollgate, OR, hosted by Run Oregon and permitted by the Walla Walla Ranger District, Umatilla National Forest. The Start/Finish is at Horseshoe Prairie, just off Oregon Highway 204, with parking across the highway at the Andes Prairie Snopark. Portable toilets and finish line snacks are available. A place to stage bags will be provided but items are not secured.
The courses run almost entirely on flowy single-track along the Umatilla Rim with short sections on forest service access roads and pavement. Courses are marked with colored flagging tape at major intersections and occasional confidence markers; runners are responsible for navigation and should study the course map. The course is open to other users, including mountain bikers, horses, and occasional motor vehicles; runners must yield and exercise caution.
