context: Thorpe began competition in 2002 at the Australian Championships in Brisbane in March, which were used to select the team for the 2002 Commonwealth Games in Manchester and the 2002 Pan Pacific Swimming Championships. After his record six gold medals in Fukuoka, the meet was surrounded by further expectations of world records and speculation that he would match Mark Spitzs seven gold medals. His winning time in the 400 m was the second fastest in history, but such was the expectation on him that his failure to break a world record was the talking point. He claimed the 100 m and 200 m events in times outside his best, making it the first time that he had failed to break a world record at a major meet since 1999. He also experimented by adding the 100 m backstroke to his repertoire, placing second. This earned him a Commonwealth spot in a seventh event, leading to further media speculation that he could match Spitz.          By this time, Thorpes relationship with Frost was beginning to unravel. Thorpe had always insisted that his swimming was about enjoyment and improving himself in setting faster times, rather than victory or defeat. This contrasted with Frost, who had a more aggressive and combative mindset, often making bold public statements. Thorpe ignored Frosts advice and bulked up his upper body by a further 5 kg to 105 kg, making him the heaviest elite swimmer in history. His reasoning that the strength gains would outweigh any loss in flexibility raised concerns over his physiological strategy. On the first night in Manchester, Thorpe again lowered his Swimming at the 2002 Commonwealth Games – Mens 400 metre freestyle by 0.09 s to 3 min 40.08 s, before anchoring the 4 × 100 m freestyle relay team to another gold. Prior to the 200 m final, Thorpe was seen arguing with Frost in the warm-up area.
