Stu Mittleman was the sixth person to be inducted into the American Ultrarunning Hall of Fame. During the 1980s, while a college professor from New York, he became the greatest multi-day runner in the country who won national championships running 100 miles, but ran much further than that in other races. During that period, no other American ultrarunner, male for female, exhibited national class excellence at such a wide range of ultra racing distances. He brought ultrarunning into the national spotlight as he appeared on national television shows and became the national spokesman for Gatorade.
