Caitlyn Marie Jenner (born October 28, 1949), formerly known as Bruce Jenner, is an American television personality and retired Olympic gold medal-winning decathlete.
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.
