AP Photo/Geert Vanden Wijngaert LONDON (AP) - Usain Bolt is as quick backtracking on his retirement plans as he is sprinting on the track. Less than three weeks ago, the Olympic and world champion announced he would stop racing after the 2016 Rio de Janeiro Olympics. But during a visit to London, Bolt said Thursday: "I am definitely reconsidering. I think my fans especially have really voiced their concern about me retiring. Pointing to commercial motives, Bolt says the fans "think I should carry on and so do my sponsors. I have discussed it with my coach and he says it is possible. The Jamaican says he is looking to extend his career by a year after the 2016 Olympics, meaning he could leave the sport after the 2017 world championships in London.
