The 25-year-old had two male hares in front of him for most of the race but ran the last part himself. She got a white towel over her shoulders and celebrated the victory and the record. Unlike Kipchoge, she will have the time officially approved as a world record.
Paula Radcliffe's previous record was at 2.15.25 and no one has been near it since she reached London in 2003.Crushed the personal record by four minutes
Many believed that Kosgei, who broke his personal record by four minutes, had gone too hard when the first five kilometers went at 15.28, a time that pointed to a finish time of 2.12 but the Kenyan held and broke the previous record.
One month ago, Kosgei won the Great North Run half marathon in Newcastle in the fastest time ever, 1.04.28, which was 23 seconds faster than the world record. But the British course was not approved for official records.
It also became Kenyan in the men's class. Lawrence Cherono won a four-run sprint and reached the goal after 2.05.45. Mo Farah, chased by journalists who wanted to know more about the Nike Oregon project, finished ninth at 2.09.58.
