Ian Thorpe - Tracey Menzies Era

Tracey Menzies Era

After the 2002 Pan Pacific Championships, Thorpe announced that he was splitting with Frost to train with one of his assistants, Tracey Menzies, who had no prior international experience. Admitting that tension existed between him and Frost, Thorpe asserted that the split was amicable. He cited waning motivation for the split, stating "I decided I either had to make the change or it was to walk away from the sport". The retired Talbot expressed concerns that Thorpe was making a decision whilst he was physically and emotionally drained, while other coaches felt that the new relationship would end up with Thorpe, rather than Menzies, making the decisions. Despite a turbulent year, he was again named by Swimming World as its World Swimmer of the Year.

Along with the switch of coaches, Thorpe indicated that he would put more focus on improving his sprinting ability. He thus dropped the 800 m freestyle despite being the reigning world champion and record holder. During this period, his times in the 400 m and 200 m freestyle deteriorated, and both he and Menzies were criticised. The criticism continued to mount during their partnership, particularly during the build-up to the 2004 Olympics. Following his victory in the 200 and 400 events in Athens, Thorpe said that his results justified his decision, despite posting substantially faster times as a young swimmer under Frost.
