Three Sisters Skyline

The Three Sisters Skyline is a trail running event held in Sisters, Oregon, featuring two race distances: a 50K and a half marathon. The 50K course offers stunning views of the Three Sisters and other Cascade peaks, with a challenging route that includes a steady 2,300-foot climb early on, totaling 3,700 feet of ascent and 4,700 feet of descent over mostly single-track trails. Runners traverse alpine meadows, Ponderosa pines, and areas recovering from a 2012 forest fire.

The half marathon is a fast, point-to-point race with a net downhill of 1,500 feet, mostly on single-track trails, ideal for achieving quick times. Both races finish in the scenic mountain town of Sisters. Visit the organization's website for the most recent information.
