( CNN ) -- He 's beaten the best sprinters the world has to offer -- but how would Usain Bolt fare against a Buenos Aires bus ? The six-time Olympic champion from Jamaica is never one to shirk a challenge , even if it means racing something 20 times his size . But while the bus -- crammed with passengers -- worked through the gears Bolt cruised to victory on 9th of July Avenue in Argentina 's capital . The stunt was part of a drive to encourage more kids to take up athletics with the 27-year-old also racing against a clutch of fellow sprinters overs 120m . Bolt told a press conference he hoped to be back in South America for the 2016 Rio Olympics to defend his 100m , 200m and 4x100m relay titles for the second time . `` One of my main goals is to go to the Rio Olympics , as I was saying , to do it again , '' he told reporters . `` To defend my titles and it 's never been done three times so , for me , that 's me trying to set the bar as high as possible . To just push the barrier . '' Bolt , who also holds the 100m and 200m world records , spoke of his first foray into running as part of the drive to boost participation in Argentina . `` The first race I actually won was when I was 10-years-old , '' he explained . `` My cricket coach bet me to run at my sportsday -- if won I would get a box lunch and I won . It was great . '' Bolt 's defeats are few and far between but he revealed the occasional reverse helps to refocus him . `` Losing helps to learn how to motivate myself to learn how to win again , '' he said . `` Winning is happiness for me .
