Kingston - Jamica Usain Bolt express his happinesss to be back on the tracks according to an interview done today by The Gleaner.

In the finals of the sprint relays at the London Olympics in 2012 and again at the Commonwealth Games in Glasgow last year, Usain Bolt got the baton almost even with the anchors for the United States' Ryan Bailey and England's Danny Talbot, respectively.

In both instances, the sprint champion pulled away from the respective anchormen to win convincingly.

On Saturday, the University of Technology's (UTech's) Tyquendo Tracey proved a different challenge.

Anchorman Tracey got the baton nearly 10 metres ahead of Bolt and the 'Lightning' man failed to catch him, as Bolt's Racers team was upset in the sprint relay for institutions at the Gibson McCook Relays at the National Stadium.UTech won in 38.23 seconds to Racers' 38.29.

While he was happy with the race, Bolt said he identified some of what he needs to work on as he prepares to defend his titles at the International Association of Athletics Federations (IAAF) World Championships in Beijing, China.

He revealed that he is in better shape than he was last year when an injury forced him to miss most of the season, but concedes that he needs to get a lot more done if he is to perform to his usual standards in China.

"I think I am getting there. I am not perfect yet. I am in better shape than last season, but I need a lot more work. My coach will now decide what else I need to focus on," he said.

One thing he doesn't lack is motivation. In his earlier years he was driven by the desire to be the best ever. The motivation this time round comes from how he feels about the way people talked about him when he was out of action for most of last season.

"For me, I will just keep working hard, continue working like I always do and bounce back, and show the world that for me it's never over," he said.

The Jamaican sprinter now has the chalenge of revalidating his world titles in 100 and 200 meters in Beijing, in the same plac when in 20008 he won the gold in 100,200 and 4 by 100 with world records in all cases.
