400 metres Freestyle, Women

Date	17 – 18 October 1964
Status	Olympic
Location	Kokuritsu Yoyogi Kyogijo, Shibuya, Tokyo
Participants	31 from 16 countries

Marilyn Ramenofsky of the United States had set three world records in this event earlier in 1964 and came to Tokyo as the favorite. In fact it was thought that the Americans could sweep the event, with Ginny Duenkel, already a bronze medalist in Tokyo in the 100 back, and Terri Lee Stickles. Ramenofsky led the final through 175 metres, when she was caught by Duenkel who gradually pulled away from her teammate. Duenkel held on to upset Ramenofsky and win the gold medal, with Stickles completing the American sweep by outlasting Australia’s Dawn Fraser. Duenkel posted 4:43.3, a personal best for her by 3/10ths of a second, but well off Ramenofsky’s world record of 4:39.5.
