Chambers' coach Mike McFarlane struggled with the workload of full-time training. Frustrated by the distance between himself and the top sprinters, Chambers decided to relocate to California to work with Ukrainian coach Remi Korchemny and nutritionist Victor Conte. After parting ways with American sprinter Tim Montgomery, Conte looked to Chambers to fill the athlete's berth. In the run up to the year's major events, Chambers was in fine form and recorded a 200 m personal best of 20.27 s in Athens on 10 June 2002. Montgomery, impressed by Chambers' training regime, tipped the Briton to win the gold at the forthcoming 2002 Commonwealth Games in Manchester, England.
