Jamaica trials boost Usain Bolt's confidence

Olympic champion Usain Bolt believes he is getting back to his best after the Jamaican trials gave him a confidence boost in the build-up to next month's world championships in Moscow.

The world record holder won the 100 metres at last month's trials to secure his place at the worlds, having been given a wild-card entry into the 200m by Jamaica as defending champion.

"The trials helped me to get a lot of runs, to define where I should be," Bolt said ahead of Saturday's Paris Diamond League event, where he will run the 200m. "And after the trials, I felt more confident. It felt great to run and actually accelerate at the end."

Bolt was beaten by Justin Gatlin of the United States in the Rome Diamond League 100m last month after returning from a hamstring injury.

But victory in the 200m in Oslo a week later, in a then-world-leading time of 19.79 seconds, followed by his win in 9.94 seconds in the 100m at the national trials, showed he was getting back to his best form.

American Tyson Gay has recorded the season's fastest 200m of 19.76 seconds since the Oslo run and tops the world leading times for the 100m with 9.75 ahead of Gatlin and Bolt.
