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.

Stuart “Stu” M Mittleman was born in New York City in 1951 to Irving Jacob Mittleman (1924-2009) and Selma R (Mitzner) Mittleman (1929-2023). His Mittleman grandparents were Jewish Russian immigrants who came to America in 1913.

When he was in high school in Dumont, New Jersey in the late 1960s, he was on the track team and ran the mile in 4:39 mile, the half mile in 2:01. He was better at wrestling in which he lettered and was a district champion. At the University of Connecticut, he continued wrestling for one season but switched to long-distance swimming and weightlifting. At Colgate University, he was on the dean’s list and earned his bachelor’s degree in liberal arts. He earned his master's degree at the University of Connecticut. He was a heavy smoker during school, going through two packs of cigarettes per day.

During the early ‘70s, he became disillusioned with the state of the country during the Vietnam War era and spent time on the West Coast, where he took up running again “for his head.” But while skiing in 1975, he had a terrible fall, tore his ACL and damaged cartilage. He had knee surgery and could not run for five months. When he could run again, he did it for relaxation and to find a quiet time for himself.

Becomes a Marathon Runner

In 1977, he ran up Flagstaff Mountain in Boulder, Colorado and fell in love with running. He went into a running store and asked how he could sign up for the Boston Marathon, three months away. They told him he needed to qualify, so he ran Mission Bay Marathon in San Diego with a qualifying time of 2:46. Early into his dream race at Boston, he was running in a drainage ditch in efforts to pass runners and twisted his ankle terribly. Disappointed, but determined, he tied ice around his swollen ankle and vowed not to drop out of the race. He finished in 4:03. He returned to Boston the next year and finished in 2:31:11. After finishing the New York City marathon six months later in 2:33:00, he couldn’t understand why he couldn’t run any faster, even though he was never tired at the end of his races. “I just started thinking, why did I have to stop? I wondered how much longer I could have run." This thought made him turn to “the longer stuff.

First Ultramarathon

Mittleman was 5’ 8” and about 140 pounds. As a graduate student in sports psychology at Columbia University, Mittleman ran his first ultra in 1978, running 6:11 in the Metropolitan 50 in Central Park, New York. That year the race was poorly organized, and the front-runner went off course, but he placed 8th with 6:13. “I ended up sprinting the last 10 miles and I was hooked.” He liked ultras better than marathons because they were less competitive and they had a friendlier atmosphere.

The 1979 Unisphere 100

With that elite performance, he qualified to enter the 1979 Unisphere 100, held at Flushing Meadows in Queens, New York, on a 2.27-mile loop road course around Meadow Lake. This 100-miler was first held in 1978, won by Park Barner in 13:57:36. In 1979,
