American colleges and universities are fast becoming training grounds not only for members of the U.S. Olympic team, but Olympians from other countries. A recent example of this was at the National Collegiate Athletic Association track and field championships in Austin, Texas. Among the many top athletes competing there, 230 came from countries other than the United States. Many of these athletes will face each other, starting on Friday, in events at the IAAF World Athletics Championships in Doha, Qatar. Clyde Hart directs the track and field program at Baylor University in Texas. Hart has worked with many Olympic champions at Baylor. “We are the minor leagues for our track and field in this country to get to the next level,” he said. College athletes are a big part of American success in winning medals at the Olympic Games.
