Janet Beth Evans (born 28 August 1971) is a former American Olympic champion who is currently a motivational speaker and corporate spokesperson for companies such as AT&T, Speedo, Campbell's, PowerBar, John Hancock, Cadillac, and Xerox.
In 1987, she broke the world records in the 400m, 800m, and 1500m freestyles. At the 1988 Seoul Olympics, she won three individual gold medals, setting a new world record in the 400m freestyle that stood for 18 years. Her 1500m freestyle record, set in 1988, was finally broken in 2007. Evans' world record in the 800m freestyle, 8:16:22 set in 1989, stood until 2008.
Evans became the first woman to win back-to-back Olympic and World Championship titles in any one swimming event by winning the 1988 and 1992 Olympic gold medals and the 1991 and 1994 World championships in the 800 meter freestyle race. Evans won the 400 meter and 800 meter freestyle swims at the U.S. National Championships 12 times each.
At the end of Evans' swimming career, she held seven world records, five Olympic medals (including four gold medals), and 45 American national titles — third only to Tracy Caulkins and Michael Phelps.
