Stunning courses with amazing views of the Three Sisters and other high Cascade peaks of Oregon. The 50K takes you to the edge of the Three Sisters Wilderness, running amongst Ponderosa Pines, remnants of a forest fire that occurred in 2012 where regrowth is occurring, alpine meadows and a picturesque mountain stream.
