Usain Bolt plots path to becoming an athletics 'legend'

Usain Bolt believes that World Championship gold is the next step to achieving the legendary status he craves within the sport.

The withdrawal through injury from the 100m of his fellow Jamaican Asafa Powell leaves the 25-year-old as clear favourite to retain his World title.

Bolt is unbeaten since losing to Tyson Gay in Stockholm last August but he has been far from his best this season, struggling with injury and loss of form.
