Kyoto (Japan) (AFP) - Closing in on his 104th birthday, a twinkle-toed Japanese sprinter has thrown down the challenge to the world's fastest man Usain Bolt, telling him: "let's rumble!"Hidekichi Miyazaki -- who holds the 100 metres world record for centenarians at 29.83 seconds and is dubbed 'Golden Bolt' after the Jamaican flyer -- plans to wait another five years for his dream race and was happy to reveal his secret weapon: his daughter's tangerine jam."I'd love to race Bolt," the wispy-haired Miyazaki told AFP in an interview after tottering over the line with a joyful whoop at a recent Japan Masters Athletics competition in Kyoto.
