Track and field star Betty Cuthbert was known as Australia's "Golden Girl." In 1956, Cuthbert set a world record of 11.4 seconds in the 100-meter dash, as well as records in 1958 (though those would later be broken). She won three gold medals in 1956 and then retired in 1960. However, her retirement didn't last long. She competed in the 1964 Olympics and won a gold medal in the 400-meter dash. Soon after, she retired permanently.
