This will be my final season: Bolt

Jamaican sprint star Usain Bolt insists this "emotional" season will indeed be his last, bringing the curtain down on a glittering career which galvanised track and field at a time of doping and corruption scandals. Bolt has won eight Olympic and 11 world gold medals but importantly was the outgoing, larger-than-life personality on whom athletics administrators could rely

Bolt has won eight Olympic and 11 world gold medals but importantly was the out going, larger-than-life personality on whom athletics administrators could rely for a positive slant, an athlete widely recognised globally. Asked whether he might carry on after this season, Bolt said: "No, I don't think so! "It's just been a great career, I've really enjoyed the ups and downs, all the experience I've gathered, It's been a wonderful career and I've done everything I've wanted to do and it's coming to an end and I'm fine with it."
