Tracy Caulkins (born January 11, 1963, Winona, Minnesota, U.S.) is a former American swimmer who is considered one of the sport’s most versatile athletes. She is the only swimmer to set U.S. records in every stroke, and she won a record 48 U.S. national swimming titles.
Caulkins began swimming when she was eight years old and won her first titles at the 1977 Amateur Athletic Union national indoor championships, where she set U.S. records in the short-course breaststroke and long-course individual medley events. In 1978 she became the first woman to swim the 200-yard individual medley in under 2 minutes, posting a time of 1 min 59.33 sec. By the end of the year, Caulkins had broken or tied 27 world or U.S. records, an achievement that was due, in part, to the ability of her knees to bend backward, which gave her a powerful dolphin-like kick when she swam. She received the James E. Sullivan Memorial Award as the top U.S. amateur athlete of 1978, becoming the youngest recipient of the honor.
Tracy Caulkins was able to hyperextend her knees backward, which gave her extraordinary flexibility and a dolphin-like kick when she swam.
Caulkins would have been favored to win gold medals at the 1980 Moscow Olympic Games but was unable to compete because of the U.S. boycott. By 1982 she had surpassed Johnny Weissmuller’s record of 36 U.S. national titles and won more titles than any other U.S. amateur athlete. While competing at the University of Florida, she won 12 NCAA championships and twice received the Honda–Broderick Cup as the nation’s outstanding female collegiate athlete (1983, 1984). She set NCAA records in the 200- and 400-meter individual medleys, the 100-meter breaststroke, and the 200-meter fly.
At the 1984 Los Angeles Olympic Games, Caulkins won three gold medals, with victories in the 200- and 400-meter individual medleys and the 4 × 100-meter medley relay. She retired after the 1984 Games, having won 48 national titles and set 66 world or U.S. records. In 1990 she was inducted into the International Swimming Hall of Fame. Caulkins later made her home in Australia, where she was awarded the Medal of the Order of Australia in 2008.
