"It's hard to explain," [Bolt] said. "I don't really know what went wrong." "I was looking to come here for a good time. I guess it's one of those days," he said. "I just never got going." "I did some starts and I was flying from the blocks so I said, "Yeah, this is good". I can't tell you what happened."
Bolt will be part of a star-studded cast that includes compatriot Veronica Campbell-Brown in the women's 100, as well as LaShawn Merritt and Oscar Pistorius in the 400, Christian Cantwell and Dylan Armstrong in the shot put, Dayron Robles at 110m hurdles, and Barbora Spotakova in the javelin.
