Having been named by Sports Illustrated as the ‘Greatest Female Athlete of the 20th Century’, Jackie Joyner-Kersee’s athletic credentials are unquestionably among the best ever, in all of sport. A six time Olympic medalist, including three Olympic gold medals, Joyner-Kersee dominated the Olympic heptathlon and long jump events throughout her career which spanned four Olympic Games.  Astonishingly, despite the advancements in technology and training used by athletes around the world over the last two decades, Jackie Joyner-Kersee still holds the World Heptathlon Record she set over 20 years ago at the 1988 Olympic Games in Seoul, Korea. – Source (Jackie Joyner-Kersee Official Website)
