Three Sisters Skyline

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.
