Three Sisters Skyline

The Three Sisters Skyline trail race takes place in Sisters, Oregon, offering a 50K and a dog-friendly half marathon each September. Both races conclude in the town center, with courses providing runners clear views of the Three Sisters and other high Cascade peaks in Central Oregon. The 50K route extends to the boundary of the Three Sisters Wilderness, crossing Ponderosa pine forests, alpine meadows, recovering burn areas, and a section alongside a mountain stream. The half marathon is a point-to-point, net-downhill course designed for faster times. Participants use a brief shuttle to the start due to limited parking at the trailhead.
