Courses are marked with ribbon approximately every 200 yards and color coded by distance; polka dot flagging marks required turns and blue ribbons mark wrong ways. Aid stations are fully stocked every 5 to 6 miles with fresh fruit, salty snacks, candy, water, and Skratch electrolyte drink; participants are advised to carry at least 20 oz of water between aid stations.
