Brussels  - American Sanya Richards, Russian Jelena Isinbayeva and Ethiopian Kenenanisa Bekele on Friday picked up 333,333 dollars each as they shared the one-million-dollar jackpot on offer at the Golden League series.

The jackpot was shared by the athletes who manage to win the same events at all six Golden League meets in one season.

Bekele looked beatable at one stage in the men's 5,000m race at the Memorial Van Damme meet as he seemingly held back, but on the final straight he proved too strong for compatriot Imane Merga, who finished 0.35 seconds behind.

Bekele's winning time was 12:55.31 seconds, while Vincent Chepkok took third place.

World record holder Jelena Isinbayeva failed at breaking her own world record of 5.07 metres in the women's pole vault, but as she managed to clear 4.70 with her first jump, she won the competition and 333,333 dollars.

It was the second time that she won a share of the jackpot and she said that some of the money would go towards orphans in her country.

She said it was not easy competing. "It was cold outside, but inside I felt I was able to jump."

Poland's Monika Pyrek and German Silke Spiegelburg took second and third place respectively with the same height that Isinbayeva cleared.

Richards won the women's 400m race - as she has in all five previous Golden League meets this season - and thus was the first athlete to be assured at least a share of the jackpot. It is the third time that she cracked the jackpot.

Richards, who also won the gold at the world championships last month, took first place in a world-best time this year of 48.83 seconds, beating Britain's Christine Ohuruogu into second place by more than a second.

Ohuruogu finished in 50.43. Jamaican Shericka Williams was third.

Jamaican sprint sensation Usain Bolt again showed that he is currently unbeatable as he comfortably took the men's 200m in a time of 19.57.

A capacity crowd of 50,000 spectators, who braved moist conditions in the King Baudouin stadium, celebrated yet another display of complete dominance by Bolt, who last month won the sprint double at the world championships in Berlin.

American Wallace Spearman was second in 20.19, while third place went to Ramil Guliyev from Azerbaijan.

The 23-year-old Bolt admitted that he felt a bit tired. "You could see that on the last 25 metres. That is why I am quite happy with my time. The spectators gave me the last push."

Although Bolt did not run the men's 100m, it was still a Jamaican double as the bronze medal winner from Berlin took first place in 9.90 seconds, beating Americans Tyson Gay (10.00) and Darvis Patton (10.88) into second and third place.

In the women's 100m race Armerican Carmelita Jeter won in a time of 10.88, ahead of Jamaicans Shelly-Ann Fraser and Kerron Stewart.

The men's Kenyan 4 x 1,500m relay team set a new world record, beating the 32-year-old previous best mark set by Germany in 1977. William Biwott, Gideon Gathimba, Geoffrey Rono and Augustine Choge won in a time of 14:36.23 minutes, to beat the oldest world record on book of the sport's governing body IAAF.

Another impressive performance belonged to Kenya's Paul Koech, who won the men's 3,000 steple chase in 8:04.05 minutes, beating his compatriot Richard Mateelong
(8:06.92).

Third place went to Finland's Jukka Keskisalo (8:13.34).

Other winners were Kenyan David Lekuta Rudisha, who won the men's 800m, Ryan Brathwaite from Barbados, who won the men's 110m hurdles in 13.30 and men's javelin winner Tero Pitkamaki. The Finn won with a distance of 86,23 m.

Jeremy Wariner won the men's 400m.

The American said that he was satisfied with his race. "I would give myself an eight. It's always nice to win in front of a big crowd. But this weather. I trained here on Monday and Tuesday, then it was ideal for a 400m."

World champion Blanka Vasic won the women's highjump with a leap of 2.00 metres. "I'm very satisfied. 2m is very good with this weather.

"I opened the window this morning and I when saw the rain I wondered how I would survive this today. But I did very well and I'm happy. Winning a Golden League is always great. This was my third competition in seven days. I'm a bit tired now," the Croatian said.

Cuban-born Yamile Aldama, who now competes for Sudan, won the women's tripple jump with 14.27m, while Jamaican Brigitte Foster- Hylton took the women's 100m hurdles.

Anna Willard from the US won the women's 800m in a time of 1:59.14 minutes.  dpa
