The Greatest World Record Ever
Thursday, April 19, 2012 at 10:34AM In 1981, Mary T. Meagher established world records in the 200 fly (2:05.96) and the 100 fly (57.93) at the U.S. Long Course National Championships in Brown Deer, Wisconsin, both of which lasted nearly two decades. Her 200 fly time was rated as the fifth-greatest single event performance of all time by Sports Illustrated magazine. Marys 100m record was broken by Jenny Thompson (U.S.A.) in 1999 and her 200m record fell to Susie ONeill (Australia) a year later.
