Bolt seeks Paris boost on his return from injury

World sprinting sensation Usain Bolt admits that he is firing at only 80 per cent, but has still targeted 9.7 seconds for his 100m outing at Friday's Diamond League meet in Paris.

The world record holder in the 100 and 200m returned from an achilles tendon injury with a clear win in 9.82sec at the Diamond League in Lausanne last Thursday.

And the Jamaican, a triple Olympic and double world champion, said his goal was now to remain undefeated during the season, which for him features no major championships.

"I definitely feel good," the 23-year-old said.

"I'm happy where I am at the moment.

"My main goal this season is to stay unbeaten. The other was to remain injury-free but that went out of the window."

He added: "I'm probably 80 per cent fit. It'll be another 2-3 more weeks before I start going full speed. The goal on Friday is definitely not to lose the race.

"I'm getting back into shape and I'll be trying to go 9.7 seconds. It should be a good race."

Bolt said he was not expecting to have everything his own way, however, from a field that includes compatriots Asafa Powell and Yohan Blake, and up-and-coming French sprinter Christian Lemaitre who set a new French record of 9.98 seconds last weekend.

"Conditions should be good on Friday, and when the competition is keen and Asafa is coming, you know it's going to be fast," he said.

"The field is hard: there's Powell, Blake, Lemaitre... a lot of guys will go under 10 seconds.

"It'll be my first time competing with Asafa this season so it should be interesting. He's in great shape this season. I'm looking forward to it. I don't want to be beaten this season."
