About

The Three Sisters Skyline takes place in Sisters, Oregon, through mountain forest and protected wilderness terrain in the shadow of the Three Sisters volcanic peaks. Runners can choose between a half marathon (13.1 miles) and a 50K ultramarathon (31 miles), both set against the rugged high-country scenery that gives the race its name. Whichever distance you pick, expect a trail run through some of Central Oregon's most striking alpine terrain, with the mountains as a constant backdrop from start to finish.
