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, running through Ponderosa Pines, alpine meadows, and areas recovering from a 2012 forest fire. It includes a steady climb of about 2,300 feet in the first 9.7 miles, totaling 3,700 feet of ascent and 4,700 feet of descent, mostly on single-track trails with three aid stations.

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