Peter Dickson Pfitzinger (born August 29, 1957, in Camden, New Jersey) is an American former distance runner, who later became an author, exercise physiologist and sports administrator.
He is best known for his accomplishments in the marathon, an event in which he represented the United States as its top finisher in two Summer Olympic Games: the Los Angeles Olympics (where Pfitzinger finished 11th) and the 1988 Seoul Olympics (where he placed 14th).
In other marathons apart from the Olympic Trials and Olympic Games, Pfitzinger won the National Sports Festival (Syracuse, New York) marathon in 1981, the Winstones (New Zealand) marathon in 1983, and the San Francisco Marathon in 1983 and 1986. He was 2nd at the Montreal (Canada) marathon in 1983. He was 3rd at the Nike OTC Marathon in 1981 and at the New York City Marathon in 1987.
He was a consistent performer: All but his first 3 career marathons were run in times between 2:11:43 - 2:15:21 (2 in 2:11, 4 in 2:12, 3 in 2:13, 3 in 2:14, and 1 in 2:15). He won 8 of his 16 marathons, and finished 2nd or 3rd in 4 others. Apart from the Olympic Games marathons, his only other finishes outside the top 3 were at the 1986 New York City Marathon (9th) and at the 1985 Marathon World Cup (Hiroshima, Japan), where he finished 18th.
Pfitzinger was awarded the DeCelle Award in 1984 by USA Track & Field as America's best male long distance runner. In 1984, he was ranked #1 U.S. Marathoner by Track & Field News and was named the Road Runners’ Club of America Male Runner of the Year. Pfitzinger was also inducted into the Road Runners Club of America Hall of Fame and Cornell University Athletics Hall of Fame.
He also holds a Master of Business Administration from Cornell's Johnson Graduate School of Management and a Master of Science in exercise science from the University of Massachusetts at Amherst.
Pfitzinger is the co-author of two highly popular training books for distance runners - Advanced Marathoning (with Scott Douglas) and Faster Road Racing (with Philip Latter). He was formerly also a senior writer for Running Times Magazine.
Pfitzinger's wife, Christine Pfitzinger, is also a former world-class runner. The Pfitzingers have lived in New Zealand—Chrissey's country of origin—since 1997.
