River Run is a top to bottom, one of several that can be done at Sun Valley. It has varying difficulties, from black to blue to green. The upper section, called Upper River Run, is a black diamond mogul run, not too bad snow, but still a huge leg burner. At 5:00 in the video, Mid River Run begins, starting at where Roundhouse Lane intersects. It is a blue run, groomed, which allows it to be skied quite fast, making it a good cruiser. Once it passes the bottom of Lookout Express, the trail becomes Lower River Run, a green run that provides a good beginner slope. Overall River Run is one the largest vertical descents on any single run, with around 3250 feet of vertical.
