"Carrying the flag is an honour," Bolt said Thursday. "For my country Jamaica, I'll do anything — to be on TV. I'm happy. I'm looking forward to tomorrow."
At the 2008 Beijing Olympics, Bolt set world records in winning the 100 and 200 metres. He also helped the Jamaican team set a world record in the 4x100 relay for a third gold medal.
But Bolt will enter the London Olympics after losing to teammate Yohan Blake in the 100 and 200 at the Jamaican trials.
