Three Sisters Skyline

Three Sisters Skyline includes a 50K and a Half Marathon held in and around Sisters, Oregon. The courses offer views of the Three Sisters and other high Cascade peaks.

The 50K travels to the edge of the Three Sisters Wilderness and runs through Ponderosa pine forests, areas recovering from a 2012 forest fire, alpine meadows, and alongside a mountain stream. The Half Marathon is a point to point course with a net downhill.

Race logistics note that runners take a roughly 15 minute shuttle ride to the start and are not permitted to be dropped off there; parking is limited near the start. Runners may bring warmups to the start; those items will be transported back by the race director's truck. Do not leave items on the shuttle as those buses do not return to the finish.

Awards and services: every finisher receives a finisher medal; top three finishers in female, male, and non-binary categories receive prizes from sponsors. Pre-race offerings include products from local sponsors and coffee, and a post-race burrito bar will be available for runners and volunteers.

The event benefits Sisters Trail Alliance, a non-profit that plans, builds, and maintains multi-user, non-motorized trails in and around Sisters. The race is held under a special use permit with the Deschutes National Forest and the City of Sisters. Visit the organization's website for the most recent information.
