The double reigning World Champion,Sifan Hassan of the Netherlands has set a new one-hour world record of 18,930m at the Diamond League meeting in Brussels.
Hassan – who is 10,000m and 1500m world champion – pulled away from Kenyan marathon world record holder Brigid Kosgei, who was later disqualified.
The 27-year-old’s effort surpassed Dire Tune’s record of 18,517m, set in 2008.
“I’m very happy. When I started, I didn’t feel good,” Hassan said. “But after I found every single minute very easy.
“It was a very strong race and I’m so happy. I never thought I was going to run so far.”
Kenyan Faith Kipyegon, the reigning Olympic 1500m champion, missed out on the 1,000m record by less than a second.
The 26-year-old finished in two minutes 29.92 seconds, with Russian Svetlana Masterkova’s record having stood at 2:28.98 since 1996.
