If you have to drop please do so only at an aid station. Please inform the aid station captain on arrival that you intend to drop and whether you need assistance. If you need to drop out away from an aid station for medical reasons you must phone the race director immediately on the number provided at check in. A sweeper bus will operate throughout the race, collecting dropped runners. Please be patient with the volunteers if you need to wait for the bus. It travels with the cut offs.
