The world's fastest man Usain Bolt says he's not out to set records this year, but that doesn't mean he'll be letting his rivals beat him.
After winning the 200 metres at the Shanghai Diamond league meeting in 19.76 seconds, Bolt said he won't be going all out because there are no major championships this year.
He's intent on staying unbeaten this season, but it won't bother him unduly if he loses the odd race.
