Usain Bolt 'feeling good' ahead of Olympics

Usain Bolt is back in full training and "feeling good," his agent said Tuesday, after concerns over an injury following successive defeats at the Jamaican Olympic trials.

Ricky Simms told The Associated Press in an email that Bolt is fit ahead of the defence of his titles in the 100, 200 and 4x100 relay at the London Games, which open July 27.

The world record-holder in both sprint distances, Bolt lost to Yohan Blake in the 100 and 200 at his national trials and had his right hamstring stretched out by a trainer after the 200.

Bolt then pulled out of the Monaco Diamond League meet on July 20 — his last planned race before the Olympics — with what his coach called "a slight problem," but Simms downplayed concerns that the injury could affect the defense of his three Olympic titles in London.

Simms also told Britain's Daily Telegraph on Tuesday that Bolt had struggled with a "slightly tight hamstring" at the trials.

"That's why, possibly, he didn't push as hard as he could have," Simms told the Telegraph. "He's back to normal ... he's good to go. The muscle tightness is gone."

Bolt's coach had decided the Olympic champion needed a little bit of massage and treatment on the hamstring, Simms said. Simms said Bolt would "train again hard next week so that he's ready for the Olympic Games."
