| Bolt unleashed his signature 'Lightning Bolt' during his victory lap |
Usain Bolt won the rematch and 200m gold as he ran a wonderful bend to once again leave rival Justin Gatlin chasing silver and fresh air.
On a sweaty, sticky night in the Bird's Nest, Bolt was out of the blocks quicker and opened up an unassailable lead over the first 100m before coming away down the straight and jabbing his thumbs at his chest as he crossed the line.
