Conor McCullough attended Multyfarnham Agricultural College in County Westmeath for two years. He then studied in the United States, first at Kent State University and later at Boston University. He competed at both the 1984 and 1988 Olympics, although it was feared he would not compete again when in 1987 he was attacked in a nightclub in Santa Monica, California where he worked in the evenings as a bouncer. He had deep knife wounds in his back and also had his right eye stabbed – he overcame his injuries, however, and won his place on the Irish Olympic team for the Seoul Olympics the following year. McCullough won three Irish hammer titles (1988, 1990-91), and his best mark of 74.16 set on 24 July 1988 at the Irish Track & Field Championships remained an Irish Championship record through 2012.
Personal Best: HT – 74.16 (1988).
