Born in Sydney, Thorpe struggled to swim as a child because of an allergy to chlorine. At the age of 15, already standing at more than 1.8 metres, Thorpe caught the worlds attention when he became the youngest world champion in history after winning the 400m freestyle. In the lead-up to the 2000 Sydney Olympics, he broke 10 world records four of them in four days at the 1999 Pan Pacific titles. In 2004, despite his split with long-time coach Doug Frost, the talented swimmer broke new ground at the Athens Olympics when he became the first Australian to win a total of five Olympic golds. Thorpe announced his retirement in 2006, but has signalled a comeback for the 2012 London Olympics.
