Catch me if you can, says world's fastest man after triple

Usain Bolt may have two more races to run this season, but his thoughts have already turned to holidays after he notched up a second treble gold at the world athletics championships.

The 26-year-old won the 100 and 200m individual titles in dominant fashion at Luzhniki Stadium and appropriately anchored the Jamaican team to victory in the 4x100m relay, the final event of the nine-day competition.

His world medal haul now stands at eight golds, the same as American women's 200m specialist Allyson Felix and retired US track stars Carl Lewis and Michael Johnson.
