holder Usain Bolt made it clear Sunday that he'll be seeking a sprint double at the Beijing Olympics in August. “I will be definitely going for the double,” Bolt said on his arrival at the Norman Manley International Airport in Kingston, just a day after he raced to a world record of 9.72sec in the 100m. The 21-year-old defied dismal weather to eclipse the mark of 9.74 held by compatriot Asafa Powell at the Reebok Grand Prix meeting in New York on Saturday night. Even after his stellar performance, the lanky Jamaican had insisted the 200m was still his favorite event, leaving some room for speculation as to whether he would pursue both in Beijing. After sleeping on it, he appeared to have made up his mind. “I broke the record, so I guess, that's the decision,” he said Sunday. “You just tell yourself that you have to do it,” he added. “I am now the fastest man in the world, so I have to run it,” he said. Powell sent congratulatory remarks to Bolt, but indicated he planned to recapture the record. “I am very happy for Bolt, he's a big guy and he trains very hard, he deserves the record,” Powell said in a statement issued through his manager Paul Doyle. “I know that I can run in the 9.6's.” Powell also looked forward to potential clashes with Bolt, including at the Olympic trials. “It will be a very exiting summer,” he said. Karpov, Chernova win In Austria, Dmitriy Karpov of Kazakhstan and Tatyana Chernova of Russia both set a world best Sunday to win the Hypo Meeting. Karpov, who led the IAAF World Challenge event after Saturday's first five disciplines of the decathlon, pulled away by winning the pole vault with a 5.30-meter jump. He finished on 8,504 points. Aleksey Sysoyev was seven points behind in second, while fellow Russian Aleksandr Pogorelov took third with 8,381. Both Sysoyev and Pogorelov earned a spot on Russia's Olympic team. In the women's heptathlon, Chernova finished on 6,618 to beat Lyudmila Blonska of Ukraine by 48 points. Anna Bogdanova, who led after the opening day, was third with 6,452 points. The 20-year-old Chernova, a junior world champion who was ninth going into the final day, won the long jump with a 6.78-meter effort and was runner-up at the javelin. Olympic decathlon champion Roman Sebrle, a five-time winner at Hypo, did not compete because of injury, while defending champion Andrey Krauchanka of Belarus was out with an illness. Olympic silver medalist Bryan Clay withdraw to concentrate on the US Olympic team trials in July.
