Bolt could run 9.4 in London: Coe

Olympic chief is expecting record-breaking performances at the Games this year

Usain Bolt, the world's fastest man from Jamaica, could possibly run 9.4 seconds over 100 meters at this year's London Olympics, Games organizing committee chairman Sebastian Coe said on Wednesday.

Asked about media reports Bolt was planning an assault on his world record of 9.58 in London, Coe said Bolt had the ability to tear up the laws of physics.
