The Three Sisters Skyline is an annual trail running event held in the charming mountain town of Sisters, Oregon. The race offers two stunning distances for runners to choose from: a 50K ultramarathon and a half marathon. Both courses take participants through scenic landscapes, including alpine meadows and Ponderosa pine forests, while providing incredible views of the Three Sisters and other Cascade peaks. The event is a celebration of the region's natural beauty and also serves as a fundraiser for the Sisters Trail Alliance, a non-profit dedicated to building and maintaining local trails.
