Jamaican track star Usain Bolt has admitted to sacrificing fast food in a bid to extend his stellar sprinting career.
In an interview with the IAAF Inside Athletics program released on Tuesday, Bolt said curbing off-track activities as the years rolled by had been easy compared to having to watch his diet.
"I've cut back on a lot of things," said the 28-year-old six-time Olympic gold medallist who had a growing reputation in his younger years for liking the nightlife and, famously, eating chicken nuggets.
"When I really realised I was getting older was last season when I got injured."
He said working his way back to fitness was a much greater struggle than when he was younger.
