Jackie Joyner-Kersee

Jackie Joyner-Kersee's heptathlon world record of 7,291 points has stood since 1988—over 35 years, making it 50% longer than #1 Serena Williams's Grand Slam record reign. With three Olympic golds and a 1991 long jump mark of 7.49 meters (24 ft 7 in), she was named the greatest female athlete of the 20th century by Sports Illustrated. Her versatility across seven events remains an unprecedented benchmark.
