Zurich: Jamaican sprint star Usain Bolt has been confirmed for the Weltklasse Zürich Diamond League here in August, officials said.

Bolt is the biggest drawing card in world athletics and will be defending his Olympic sprint titles at the London Olympiad which starts in July.

The Weltklasse Zürich meet runs off Aug 30, just weeks after the conclusion of the London Olympics August 12.

"It will be great to be back at Weltklasse Zurich. I have great memories of the fantastic organisation and passionate crowd at the Letzigrund Stadium," Bolt said.

"Zurich is often called the one day Olympics and I expect this year to be a very special meeting 18 days after the London Games."

Bolt has not yet indicated which sprint he will contest, with both events on the card.

The World record holder in both events, Bolt won the 100 metres here in 2008 in the wake of his stunning performances in Beijing and returned to win the following year, just after similar histrionics at the Berlin World Championships.

Organisers said they were anxiously looking forward to Bolt's presence.

"Usain is the most popular track and field star of the millennium. We are delighted to have him back in Zurich," said meet director Patrick K. Magyar.

Bolt launched his season in style two weeks ago when he posted a world-leading time 9.82 seconds in the 100 metres. (IANS)
