Umatilla Rim Ripper

The Umatilla Rim Ripper is a trail race event in Tollgate, Oregon, hosted by Run Oregon. The event offers four distances with courses that use mostly single track trail along the Umatilla Rim and short sections of forest service access road and pavement. Runners will see vistas of the North Fork Umatilla Wilderness and mixed forest terrain.

Distances:

  • 23-Miler 22.8 miles, ~2324 ft vertical gain
  • Half Marathon 13.6 miles, ~1434 ft vertical gain
  • 11K 6.8 miles, ~691 ft vertical gain
  • 7K 4.5 miles, ~423 ft vertical gain

Courses are marked with colored flagging tape at major intersections and occasional confidence markers, but runners are responsible for navigation. The route is not closed to the public; other trail users, including mountain bikers, horses, and motor vehicles on a short paved road section, may be present. Pacers and pets are not allowed.

Aid station support varies by distance: four stations for the 23 mile, two for the half marathon, and one each for the 11K and 7K, plus a start/finish aid station. This is a cup less course so runners must carry a drinking vessel. Portable toilets, finish snacks, and bag staging will be available at the Start/Finish at Horseshoe Prairie off Oregon Highway 204. Parking is at Andes Prairie Snopark across the highway.

The event has a 2pm course cutoff. Race day bib pickup begins the morning of the event. Registration follows published windows and pricing and refunds are not offered. The event is USATF sanctioned and permitted by the Walla Walla Ranger District, Umatilla National Forest. Visit the organization's website for the most recent information.
