Usain Bolt Shatters his Own 2009 Beijing Olympics Record, Clocks 9.58 in 100M at IAAF World Championships to Beat Tyson Gay (VIDEO)

UPDATE

After a phenomenal year, Usain Bolt has pulled out of the Daegu Pre-Championship Meeting in South Korea this month citing fatigue, organisers say. His withdrawal means he is also likely to miss the Shanghai Golden Grand Prix which takes place five days earlier.

"Bolt's agent on Wednesday informed us that he cannot take part in the competition in Daegu due to his not-good physical condition," said an official from the Daegu organising body. "We feel really sorry not to have him at the competition given the huge publicity effect he can bring to any athletic event."
