Course
50K Course
Out and back course. Run commences from Sunrise Trailhead parking area and follows Pacific Crest Trail North to Mason Valley Truck Trail, where runners will begin their descent down Oriflamme Canyon into the desert. At the base of Oriflamme Canyon, runners will turn onto the California Riding & Hiking Trail, crossing S2 and then proceeding through Box Canyon into Blair Valley and the turnaround point.
Overview: 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. There is a 9 hour time limit for this run. 150 runner limit. Technical t-shirt to all entrants and medals to all finishers. Early 6:00 a.m. start is available for those of you wishing to do a little sightseeing.
