Stanfield, who has always been considered an "iron man" by his friends, partners, and competitors, showed no signs of wearing down. He had made it through his first 16 hours without a hiccup, and was getting faster as time went on. Each pit stop, about every hour on average, he assured the crew that he was feeling great and would have no problem finishing the duration of the run. "We knew that Wayne would hold up well" commented Walksler of Stanfield, who had undergone strict diet, exercise, and sleep regiments in preparation for the run. "Our biggest worry was his ability to maintain speed at night, and he showed us that wasn't a problem."
