The 2011 edition of the "Usain Bolt Show" begins this weekend in Daegu, South Korea, when the 13th Track and Field World Championships start a nine-day run (August 27-September 4).
Bolt, who won dominating sprint victories in both the 2008 Beijing Olympics and the 2009 Berlin World Championships, has looked merely mortal this season, winning races but not running particularly fast, especially by his world record standards.
Bolt will benefit by the absence of American star Tyson Gay (the last sprinter to defeat Bolt) due to injury. The Jamaican’s main competition will come from fellow countrymen, especially Asafa Powell in the 100 meters.
The meet will serve as a clear preview of the track and field competition at next summer's Olympic Games in London.
