KINGSTON (AFP) - Beijing Olympic sprint star Usain Bolt was pleased with two runs on winning relays here Saturday at the Gibson Relays, but says more work is needed to get into top shape. "Overall I think I did pretty well, but it was a little bit tiring, because I am not in the best shape," Bolt said. "But I am getting there." Bolt, who won Olympic 100-meter gold in a world record 9.69 seconds and took 200m gold in a world record 19.30 seconds, helped his Racers Lions Club in the 4x100-meter and mile relays. In the 4x100, Bolt led his team home in a meet record 38.10 seconds, the fastest time in the world this year, eclipsing the 38.62-second performance by Jamaican Asafa Powell's MVP squad at the Sydney Classic. The time beat the previous meet record of 38.70 set by the High Performance Centre in 2007 and was .38 ahead of the runner-up Racers Track Club, the second of the Glen Mills-coached group on show. Bolt returned later to run the third leg of the Racers Lions mile relay. The team, which included Olympic 400m semi-finalist Ricardo Chambers and Commonwealth Games bronze medalist Jermaine Gonzales, won in 3:04.27.
