Course
The 50K runs to the edge of the Three Sisters Wilderness through Ponderosa pine, past ground scarred by wildfire, alpine meadow and alongside a mountain stream. The half marathon is a point-to-point with a net downhill that produces fast times. Both run on mountain trail in the Oregon Cascades.
