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 climbs about 3,700 feet and descends 4,700 feet, mostly on single-track trails through Ponderosa Pines, alpine meadows, 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, primarily on single-track trails, ideal for runners seeking speed and scenic vistas.

Both races finish in the mountain town of Sisters, providing a vibrant atmosphere and support from local aid stations. Visit the organization's website for the most recent information.
