Kenya’s Priscah Jeptoo surged clear to win a sombre London Mara­thon on Sunday, as runn­ers paid tribute to the victims of the bomb attacks at the Boston Marathon.
Jeptoo, the silver medallist at last year’s London Olympics, streaked away from the women's field to claim victory ahead of compatriot Edna Kiplagat and Yukiko Akaba of Japan.
In the men’s race, British Olympic star Mo Farah helped set the early pace before dropping out, as planned, after an hour.
Earlier, a 30-second period of silence was observed prior to the start of the elite men’s and mass races, in tribute to the three people killed and around 180 injured in Monday’s twin bomb blasts in Boston.
Competitors also sported black ribbons in memory of the Boston victims, while the police presence was increased by 40 percent.
Despite security fears, organisers said 700,000 people took to the streets of London to watch the race on a day of blue skies and bright sunshine in the British capital.
