Elevation gain by distance ranges from 710 feet for the 8K to 4,530 feet for the 50K. Surfaces are primarily single-track and dirt road with some asphalt. Fully stocked aid stations appear every 5 to 9 miles with fruit, salty snacks, candy, water, and Skratch drink; runners are advised to carry at least 20 oz of water between aid stations.
