World Athletics Championships

Starting Friday 4th August - BBC One, BFBS Channel 2 (BBC Two) & BFBS Sport

London prepares to host its biggest event since the glorious success of the 2012 Olympic Games, the World Athletics Championships. The event promises to provide a send-off to Usain Bolt, as the eight-times Olympic champion looks to sign off in his last major event by adding to 11 world championship gold medals.
