The third event in the annual “Run Big Trail Series”. The Annual Ridgeline Ramble trail running classic covers the entirety of the Ridgeline Trail in South Eugene, over Memorial Day weekend. The 20K and 10K courses are approximately 80% trails and dirt roads, with the remainder on paved roads. The trails are hard packed dirt and bark chip, with some rocks, roots, and a stream crossing. The 20K has a 459′ net elevation drop from start to finish, while the 10K drops 341′ from start to finish. The relay exchange point is the same as the 10K start location. The 20K starts at the Blanton Road trailhead, while the 10K starts at the Fox Hollow trailhead. Shuttles provided from LCC.
