Usain Bolt is sacrificing fast food in a bid to extend his sprinting career. In an interview with the IAAF Inside Athletics programme, the 28-year-old said he had cut back “on a lot of things”. “I’ve started eating healthy. That’s the hardest thing for me right now is the sacrifices, eating vegetables all the time,” said Bolt, who had a reputation in his younger years for liking the nightlife and eating chicken nuggets. “Everything else is easy to give up, but eating healthy is really hard.” Bolt who has been struggling with a pelvic injury is due to compete at the Diamond League meet in London on Friday.
