Caitlyn Jenner, 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 requiring surgery. Coach L. D.

After intense training, Jenner won the 1976 Olympics decathlon title at the Montreal Summer Olympics, 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.Jenner has six children from marriages to ex-wives Chrystie Crownover, Linda Thompson, and Kris Jenner. Since 2007, Jenner has appeared on the reality television series Keeping Up with the Kardashians with Kris, their daughters Kendall and Kylie Jenner, and step-children Kourtney, Kimberley, Khlo�, and Rob Kardashian.
