Umatilla Rim Ripper : Tollgate, OR (September 26, 2026)
The Umatilla Rim Ripper is a trail running event hosted by Run Oregon in Tollgate, Oregon. The event uses mostly single track on the Umatilla Rim Trail with a short section of forest service access road and pavement near the finish. The course is open to the public during the race; runners may encounter other trail users and motor vehicles on the access road and must yield and exercise caution.
Four distances are offered:
- 23.0 miles (22.8 miles listed) with about 2,324 ft vertical gain
- Half marathon (13.6 miles) with about 1,434 ft vertical gain
- 11K (6.8 miles) with about 691 ft vertical gain
- 7K (4.5 miles) with about 423 ft vertical gain
Courses will be marked with colored flagging at major intersections and occasional confidence markers, but runners are responsible for navigation. The 23 mile distance is new for 2026. Pacers and pets are not allowed on course.
Aid stations and logistics: aid station counts vary by distance and provide water, electrolytes, and fuel as described by distance. There is an aid station at the start/finish for all runners. This is a cup less course; runners should carry a drinking vessel. Reusable bottles will be available for purchase at the start line for cash only.
The Start/Finish is at Horseshoe Prairie near Oregon Highway 204 with portable toilets, finish snacks, parking across the highway at Andes Prairie SnoPark, and a place to stage bags without formal security. Bib pickup occurs the morning of the event. Registration via the event platform closes the Wednesday before the race and race day registration is available with an added fee. Organizers are monitoring wildfire activity and may use an alternate course if the Rim Trail is closed. Visit the organization's website for the most recent information.
