After lighting up London 2012, six-times Olympic gold-medallist Usain Bolt has tweeted a goodbye from Heathrow Airport.
The Jamaican, looking typically relaxed, rode shotgun in one of the airport's buggies ahead of travelling back for a homecoming in the Caribbean.
Bolt retained his 100 and 200 metres Olympic title at the 30th Olympiad, before going on to win the 4x100m relay sprint again with a world record time.
Along with Yohan Blake, Nesta Carter and Michael Frater, the quartet ran the race in 36.84 seconds.
