With the 2000 Sydney Olympics approaching, Chambers studied the technique of other sprinters. In an interview with BBC journalist Tom Fordyce, Chambers commented on the stamina Greene and Surin had gained from running in the 200 metres event and Jason Gardener's improved acceleration through running the 60 metres event. He experimented with distances at the beginning of 2000, sprinting over 50, 60 and 200 m in various competitions. He set a personal best of 6.55 s in the 60 m event in Ghent in February. A hamstring injury caused him to miss six-weeks of training and when he returned his 100 m performances were lacklustre. He finished ninth at the Golden Gala in Rome with a slow time of 10.41 s and was seventh in a tame 10.30 s at the London Grand Prix, results that led him to consider quitting the season altogether. A late rejuvenation at the British Olympic trials guaranteed his selection as he snatched first place with 10.11 s (just one hundredth of a second ahead of Darren Campbell). Victory against in-form world record holder Maurice Greene in Gateshead raised Chambers' confidence and he stated his aim to take home a medal from the Games.
