Bolt was less enthusiastic, and demanded that he feel comfortable in his sprinting. He suffered another hamstring injury in March 2006, forcing him to withdraw from the 2006 Commonwealth Games in Melbourne, and he did not return to track events until May.

Usain Bolt not being at full fitness, he took the 100 and 200 m titles at the Jamaican national championships, with runs of 9.86 s and 20.25 s respectively.

Rival Tyson Gay suggested that Bolt's 100 m record was within his grasp, but Bolt dismissed the claim and instead noted that he was more interested in Asafa Powell's return from injury. Bolt defied unfavourable conditions at the Athletissima meet in July, running 19.59 seconds into a 0.9 m/s headwind and rain, to record the fourth fastest time ever over
