Powell leads sprint chase of world beater Bolt

Usain Bolt better not be celebrating his 2008 success too much if he wants to stay ahead of a hungry pack of sprinters, former 100 metres world record holder Asafa Powell said this week.

"If he is not working as hard as he did last year, he'll be in trouble," Powell told reporters about his fellow Jamaican at a news conference for today's Reebok grand prix meet in New York.

"You can get on top so fast, but you can jump back even faster. You have to really work to stay on top because there are some guys coming at you. You have to work harder and harder each year."

Powell counts himself as one of the gang chasing Bolt, who set world records in winning the 100 metres, 200 metres and 4x100 metres relay at the Beijing Olympics.

Powell begins a 2009 quest to reclaim his 100 metres record today in a race that also includes Olympic silver medallist Richard Thompson of Trinidad.

Bolt announced himself as a world beater last year at the Reebok grand prix by breaking Powell's 100 metres mark of 9.74 seconds with a time of 9.72.

Bolt, who ran a spectacular 9.69 in the Beijing final, is skipping the New York meet but his impact is unmistakable.

"It is the benchmark for sprinters worldwide," Thompson said about Bolt's times.

"Having run 9.6, all the people are going to be working harder, working smarter. You're going to see more people running faster."

Powell, who has been sidelined this year by a left ankle injury, held the world record from 2005 to 2008.

"Before I was the target so I know what it's like to be shot at," he said.

"Now Usain is the target. Everybody is going after him. I'm going after him also. I think everyone is training to run 9.6 because Usain showed that it's possible."
