Experience dramatic scenery, demanding trails and genuine support on this point-to-point mountain course. The Castle Peak 100k trail race starts near the historic Donner Camp in Truckee, California, where runners will climb (and descend) some 14,000 feet at an average elevation of 7,100 feet. The course tours the Tahoe National Forest, Tahoe Donner, Donner Lake Rim Trail, Basin and Castle Peaks, Royal Gorge and Sugar Bowl before descending Cold Stream Canyon to the finish at Donner Memorial State Park. Please be advised that the course includes a 1.25-mile section (the Palisades) of very technical, risky and exposed scrambling and may not be appropriate for those with a fear of heights.
