Olympic and world champion Usain Bolt won the 100 metres with a late surge at the Weltklasse Golden League meeting on Friday while Russian Yelena Isinbayeva broke her own world record in the women's pole vault.

Bolt, who was paraded around the Letzigrund stadium in a rickshaw before the meeting, was slow out of the blocks and trailed fellow Jamaican Asafa Powell with about 20 metres left.

But the irrepressible Bolt, who last week smashed the world record in astonishing style with a time of 9.58 seconds at the world championships in Berlin, found an extra burst of speed to win in 9.81.

Isinbayeva atoned for her Berlin flop by clearing 5.06 metres to beat her previous record set at last year's Beijing Olympics by one centimetre.

Ethiopia's Kenenisa Bekele, world and Olympic champion at 5,000 and 10,000 metres, comfortably won over the shorter distance in 12 minutes 52.32.

Bolt, the world and Olympic champion over 100 and 200 metres and world record holder in both sprints, finished the evening by producing an electrifying last leg as Jamaica won the 4x100 relay to beat the U.S. by three hundredths of a second.

"I would say this was a shaky race," Bolt said after the 100. "My body was sitting at the start, I was a little bit tired through the race.

"At the end, I needed to pick up my speed as my body did not respond well to the race."

Powell, third at the worlds, said: "This race gives me a lot of assurance that I can win races. I just need to work on the last part of the race.
