Athletics: Manchester City Games

John Inverdale presents live coverage of the Great City Games, taking place on the streets of Manchester. 2009's inaugural event was lit up by triple Olympic gold medallist Usain Bolt, who ran a world record time in the 150m and there are plenty of top-class athletes on the bill once again. American Tyson Gay will attempt to break the straight 220-yard dash world record, currently held by the legendary Tommie Smith, who will be a special guest at the Games
