Umatilla Rim Ripper, Tollgate OR

The Umatilla Rim Ripper is a trail running event held at Horseshoe Prairie near Tollgate, Oregon, hosted by Run Oregon. The courses run primarily on single-track Umatilla Rim Trail with a short section of forest service access road and offer views of the North Fork Umatilla Wilderness. The Start/Finish area is located just off Oregon Highway 204 with parking available across the highway at the Andes Prairie Snopark. Portable toilets and finish-line snacks are provided.

Distances offered:

  • 23-Miler (22.8 miles) with ~2324 ft vertical gain
  • Half marathon (13.6 miles) with ~1,434 ft vertical gain
  • 11K (6.8 miles) with ~691 ft vertical gain
  • 7K (4.5 miles) with ~423 ft vertical gain

All courses are marked at major intersections and include occasional confidence markers; runners are responsible for staying on the course. The course is not closed to the public and other trail users, including mountain bikers, horses, and occasional motor vehicles, may be present. Pacers and pets are not allowed. Spectators and crew may access the Start/Finish and aid station areas but are asked to remain off the course when possible. There will be an aid station at Start/Finish and additional stations on each distance; this is a cup-less course and runners are expected to carry a drinking vessel. A small number of reusable bottles will be available for purchase at the start line for cash only.

The event supports local youth programs, including the Weston Middle School Athletic Program and Athena Weston Youth Sports. Event sponsors include CHI St. Anthony Hospital, Edwards Jones, and Monahan, Grove and Tucker Law Firm.

A fire season update notes that the Hagen Fire has progressed across and around the rim trail, affecting the Rim Ripper course; planned alternate routes are unlikely to be viable given recent fire activity and contingency line work. Visit the organization's website for the most recent information.
