You have beaten every people the best of the best when it comes to sprint race. So, is there any challenge left?

Usain Bolt, a two-time Olympic Gold medalist in sprint, is the fastest guy in the world. He has dominated the last two editions of the Olympics. He is running out of challenge and the one he turned to? A bus.

The Jamaican sprinting legend was in Buenos Aires, Argentina last week to attend an exhibition road race. He also participated in a special 120m race event that pitted him against compatriots Mario Forsythe and Kimmari Roach and Antiguan runner Daniel Bailey. The race took place in the city's famously wide 9 de Julio Avenue. However, what made the loudest noise in his Argentina visit was his battle against a bus.

Who won?

The race was broadcast live on an Argentinian network and millions of locals were able to witness on hand how fast 'Lightning' Bolt can run.  He outran the gargantuan piece of metal in an 80-meter race without even sweating, without even a sign of seriousness. But of course, the 27-year old Jamaican sprinter was able to edge the bus because the vehicle takes time before moving on such a high speed.

Bolt appeared so happy about his win and shooked the hands of the defeated driver and later on did his familiar race pose in front of the bus, in front of over 30,000 live spectators.

New Challenger?

After the fun race in Buenos Aiers, Bolt dared Chinese bus drivers to race against him his Weibo, China's version of Facebook,.

"Are there any Chinese buses want to race against me?" he asked.

His post generated a lot of reactions and quickly, a woman named Wang Ying, a public bus driver in Dalian with 15 years' experience, said she was ready for the challenge.

So far, Bolt hasn't made any press release whether the race between him and Wang will push through.
