Come watch the sunrise over the desert and then run down into it. It's a 50K with a little bit of everything... single track along the Pacific Crest Trail, a more than 2,000 foot drop into the desert, a run through the beautiful desert scenery of Box Canyon, and then the climactic 5+ mile climb back up via Oriflamme Canyon.
