Bolt targets season world 100m best

World record holder Usain Bolt has targeted a season's 100m best at Friday's final Diamond League meeting of 2011 to help ease a little of the lingering pain of his sensational world championships disqualification. Olympic champion Bolt, who saw compatriot Yohan Blake take his world title in Daegu last month after his infamous false start, believes the Memorial meeting track in Brussels will encourage a fast time. "I really want this world year best and I feel good. I think I have it in me to run the fastest time of the year. The track in Brussels is simply excellent", said Bolt, who has fellow Jamaican Asafa Powell's season-best of 9.78sec in his sights. Bolt, who still managed to win gold medals at the world championships in the 200m and 4x100m, arrived in Belgium straight from Zagreb where he ran 9.85sec on Tuesday, his best time of the season. "Whether I'm more nervous at the start now? Not really, but it does linger on in my mind a bit," he admitted. "As a professional, I have to learn to deal with such matters. "There's always room for improvement. For example, the first 30 to 40 metres in the 100m. By continuing to work hard, I think that I can ran faster still." Bolt won't have to worry about Blake in the 100m on Friday as his countryman will race only in the 200m on Friday. Blake showed in Zurich and Berlin over the last week that his world title performance was no one-off, twice clocking 9.82sec.
