[Dawn Fraser] was gone, after having won the event in 1956, 1960, and 1964, and in her absence, there was no real favorite. [Sue Pedersen] had won the US Nationals and Olympic Trials over [Jan Henne] and they both made the final, each winning a semi, with Canada’s [Marion Lay], silver medalist at the 1967 Pan American Games, winning the first semi. In the final Pedersen led by inches at the turn, but Henne surged past her to win the gold medal, with the Americans sweeping, Pedersen in second, and [Linda Gustavson] winning bronze, Lay placing fourth.
