The Jamaican sprinter who has twice taken bronze in the world 100 meter final but on two other occasions missed the championships with groin trouble, confesses that Olympics 2012 is his last chance to erase disappointments of the previous two Olympic finals.

Powell also confirms that one individual title the 2006 Commonwealth Games is a poor reward for his evident talent, and grabbing the gold in the 100 meter event in London is the final opportunity to stand among genuine title contenders.

“This is an important Games for me. This is probably my last one and I am going to give it my all. The 100m is my event because the 200m doesn’t love me very much and the feeling is mutual. I have learnt from Usain to stay more relaxed. I’ve learnt from him that you are doing it for yourself and no one else. It’s easier for me now. The final is a one man race in that you just solely focus on your lane and you don’t look around you and size up the opponents,” said Powell.

The 29-year-old, who held the 100m record for almost three years from June 2005 to May 2008, admits that the Olympic 100 meter event will be one of the most cut-throat competitions in Olympics history.
