I want to talk about one of the greatest athletes of Ukraine, Yana Klochkova. She started swimming at age six. Ever since childhood, Jana has showed outstanding results in swimming. During her career she managed to set 50 records of Ukraine. She twice represented our country at the Olympic games. For the first time Jan has won two gold medals and one silver medal in 2000 in Sydney. The second time she won two gold medals in 2004 in Athens. In Sydney she set a world record in the men's 400 meters and European record in the 200m individual medley. For his outstanding talent swimmer in the people began to call her “goldfish”. All the credit and rewards even difficult to enumerate. Unfortunately, the sports career does not last long. In 2008, Ian left the sport. However, her glorious achievements will forever remain in history.
