Jenner was a college football player for the Graceland Yellowjackets before incurring a knee injury that required surgery. Coach L. D. Weldon, who had coached Olympic decathlete Jack Parker, convinced Jenner to try the decathlon. After intense training, Jenner won the 1976 Olympics decathlon event at the Montreal Olympic Games, gaining fame as "an all-American hero". Jenner set a third successive world record while winning the Olympics. The winner of the Olympic decathlon is traditionally given the unofficial title of "world's greatest athlete". With that stature, Jenner subsequently established a career in television, film, writing, auto racing, business and as a Playgirl cover model.
