The synthetic rubber surface was poured into place rather than rolled out like a carpet to ensure consistency and energy efficiency.

"I think Zurich is probably the most advanced track there is in the world," Magyar said.

"It needs time to settle in so we expect the track to be in better condition for the athletes than last year."

Bolt is slated for a rematch with Olympic runner-up Richard Thompson of Trinidad and Tobago and Walter Dix of the United States, who won the bronze medal.

The 100-meter record has been equaled or broken on three previous occasions at the meet.

In 1960, Armin Hary of West Germany clocked the first 10.0 time, while Carl Lewis in 1988 equaled the 9.93 mark he shared with fellow American Calvin Smith.

Two years ago, Bolt's Jamaican rival Asafa Powell ran 9.77 for the third time.

Bolt ran the 200 at Weltklasse last year, clocking 20.19 to finish second behind Xavier Carter of the United States.

He was also beaten at the 2007 Athletissima, where his 20.11 run trailed far behind American Tyson Gay's time of 19.78.

Pasche said Bolt has missed the meet just once since debuting in 2003 but has never won there. World record or not, that streak seems sure to end.
