Greene: Bolt on another planet

Former world champion Maurice Greene believes Usain Bolt remains in a world of his own as the Jamaican begins his attempt to add World Championship glory to his three Olympic gold medals.

Greene won the world title three times in succession (1997, 1999 and 2001) and believes Bolt will relieve defending champion Tyson Gay of his 100 and 200 metres titles in Berlin.

“Usain is running on Mars, everyone else is still running on Earth,” insisted Greene, who dominated the sport on his way to world titles in Athens, Seville and Edmonton.

“I would tell Tyson Gay to try to block everything else out. The only person in the race is you. That’s how you have to go into it.

“In the 2000 Olympics I told my manager it was my gold medal to lose and that’s how Tyson has to approach it. That’s how his mindset has to be. He has to believe.”

The first two rounds of the 100m take place today with the semi-final and final scheduled for Sunday in an explosive start to the championships.
