<p>A career that altered the sprinting landscape forever made its final Olympic bow on Friday. Usain Bolt, athlete without a parallel, signed off with a flourish – another gold medal in the 4x100M relay completing an unprecedented triple-triple for the man from Jamaica.<br /><br /></p>.<p>Bolt will be back next year for one final hurrah at the World Championships but never again on the Olympic Games, an arena that he lit up with his incredible talent, spectacular performances and sunny personality.<br /><br />The Jamaican, who turns 30 on the final day of these Olympic Games, leaves with a bag of records which is unlikely to be matched anytime in the near future. The latest addition came with a note of predictability when he anchored the relay squad, featuring Asafa Powell, Yohan Blake and Nick Ashmeade, to victory in 37.27 seconds, against surprise packets Japan.<br /><br />With 100, 200 and 4x100 gold medals from three Olympic Games making up a tally of nine, Bolt joins another exclusive club that features Paavo Nurmi and Carl Lewis, also winners of nine Olympic titles.<br /><br />“There you go, I am the greatest,” declared Bolt after giving himself the perfect birthday present. “As soon as I got the baton, I knew I was going to win this one, because there is none to outrun me in the anchor leg.<br /><br />“I am just relieved it has happened, it has been a lot of pressure, I am just happy, proud of myself. I am also sad that this is my last one, I am going to miss the crowd, the energy and the competition, I just love competing.”<br /><br />The Jamaicans were almost on par with the United States and Japan when Bolt got the baton in the relay. In just a few strides, he set that straight and blazed away to the finish, leaving Japan and the Americans in a fight for minor medals. With the American anchor Trayvon Bromell struggling, the Japanese edged ahead in an Asian record of 37.60 while the United States, who finished third, were disqualified for an exchange zone violation.<br /><br />Bolt’s farewell round was graced with Jamaican razzmatazz as the quartet displayed its dancing skills and mingled with the fans for selfies and pictures.
