Patti Catalano Dillon (née Lyons, April 6, 1953) is a former long-distance runner from the United States who is recognized by the International Association of Athletics Federations as having set world bests in the half marathon, 30 kilometers, and 20 kilometers.
She grew up in Quincy's working-class Houghs Neck neighborhood, the eldest of nine children. Her father was second-generation Irish from Dorchester and an all-Navy boxer. Her mother, a Micmac Indian, had run away from home in Nova Scotia when she was 11 and wound up in Quincy working as a nanny after lying about her age.
Catalano has held American road records in the marathon, half marathon, 30 kilometers, 15 kilometers, 10 miles, and 5 mile (now 8 kilometers). Described as "one of the most dominating American female road runners of the 1970s" and "the queen of U.S. women distance runners", she was inducted into the National Distance Running Hall of Fame in 2006.
Catalano won five of the first six runnings of the Ocean State Marathon (1976-1979, 1981) and four consecutive at the Honolulu Marathon (1978-1981). Included among the many races she has won are the Montreal International Marathon (1980), Crim 10 miler (1980, 1981), the Crescent City Classic 10 km (1980, 1981), and the Rio de Janeiro Marathon (1985).
In 1992, Catalano married her fourth husband, Danny Dillon. Dillon was a Big East champion in the 3,000 meters and a cross country All-American at Providence College. As of 2003, they live in New London, Connecticut with their two children.
