London 2012 Olympics: Dwain Chambers to run against double world silver medallist Walter Dix in Manchester The event is in its fourth year and has previously hosted star names such Usain Bolt and Tyson Gay, but this will be the first time that Chambers has been offered a lane by the organisers, Nova International. Since being cleared to compete at the London Olympics, the 34-year-old has been handed the chance to compete against Bolt in Ostrava on May 25, while UK Athletics has indicated he will be offered a 4x100m relay spot at the Diamond League meetings in Rome and at Crystal Palace. Chambers, who has spent the last seven weeks training in Kingston with former world record-holder Asafa Powell, will face a stiff test in Manchester as he will be up against American Walter Dix, the world 100m and 200m silver medallist, Richard Thompson, the Trinidadian who won 100m silver at the 2008 Beijing Olympics, and fellow Briton Marlon Devonish. Bolt set a world best of 14.35sec for the rarely run 150m distance at the inaugural Manchester meeting in 2009. Devonish holds the British best mark of 14.87sec.
