2011 Diamond League 100m champion and former world record holder Asafa Powell is not ruling out the possibility of next year's Olympic Games in London being his last but at the same time, is not quite ready to put a timeline on his swan song as yet.

By the time the 2012 Olympic Games start in July next year Powell will be a few months shy of his 29th birthday, while he'll be chasing 33 when the 2016 Olympic Games, which are scheduled for Rio De Janeiro gets under way.

Powell, who will next month be receiving the University of Technology's Chancellor's Medal in recognition of his achievements in the sport, says he will certainly be approaching the London games as his last, though he would not explicitly rule out the possibility of him featuring in 'Rio'.

"I will approach it as if it's my last Olympics," said Powell.

"You definitely have to go into these championships as if it's your last and I will approach London as if it's my last."

"I am never going to give up until it's really time. I am here and I'll continue to be here until my time comes," Powell added in reference to his resilience and determination.

In his two appearances at the Olympic Games, Powell is yet to win an individual medal and has only managed a 4x100m relay gold at the 2008 Games in Beijing, China.

At the Athens 2004 games, Powell ran 9.94 for fifth place in the 100m final, returning four years later in Beijing with a similar performance and finish; crossing the line in 9.95, which was once again only good enough for fifth.

The two-time World Championships 100m bronze medalist, who had to sit out this year's 'Worlds' after he failed to recover in time from a groin injury, is already focusing on the upcoming season and will be watching his fitness situation over the next week or two before going into full training.

"I will start working on that (injury) maybe next week, and I think the real training will start in three weeks or so," said Powell.

"Honestly, I just want to take it step by step, I have to get the training out of the way and then I have the national trials and then on to London, so it's a step by step process and I just want to make sure I am fit and in great shape heading there," Powell added.
