Mary Keitany breaks a marathon record with 3rd London win

Radcliffe had also been the holder of the women's-only record thanks to her time in the 2002 Chicago Marathon but Keitany squeezed past that by 17 seconds.

In the men's race Kenyan Wanjiru held off the challenge of Kenenisa Bekele, who holds the 5,000 metres and 10,000 metres world records as well as eight Olympic and world titles, to win in 2:05.48.

Keitany beat Ethiopia's Tirunesh Dibaba, who finished second, after Dibaba began to struggle on the Embankment, even stopping at one point as she appeared to clutch her stomach. Only Paula Radcliffe, whose outright world best of 2:15:25 in the 2003 London marathon was set with the help of male pacemakers, has ever gone faster.

Mary Keitany and Daniel Wanjiru's spectacular performance at the London Marathon Sunday speaks volumes of Kenya's athletics prowess.

Mary Keitany also said in a post marathon interview, "It was a long time that I had not beaten a record". I felt my hamstring and my right calf.

She said all this with the sort of calm fluidity that mirrors the action of a marathon runner in motion, but combining motherhood with professional sport her way has undoubtedly been a detour to her previous approach to her job.

Wanjiru made his break rather later, the Kenyan going clear with five miles left to leave a string of world-class athletes behind him.

Karoki finished one minute 53 seconds down in third on his marathon debut.

Every £1 raised and every step of the 26 miles will be dedicated to Paul's dad, Margaret, Chrissie and the many others who have suffered from this bad illness.

"I've had a lot of background problems in my personal life".

She continued: "I dedicate each mile to someone or something that I love during marathons but I always keep the last mile for my dad".

"All I was thinking was "win, win, win".

She said: "Everyone was doing the marathon for their own individual reasons and when you start to get to know people more and you realise why they're running it, it gives the charity a whole new meaning for you - and in the end you're running for everybody".

Hug was just one second behind with Spain's Rafael Jimenez snatching third in 1:31:09.

Last year's men's and women's champions were missing from this year's race for different reasons.

After breaking the world best in Boston six days ago, Schär was again a class apart as she won by more than four minutes from Amanda McGrory with Susannah Scaroni third.

Asked if he had erased the memories of Rio, Weir said: 'I think so.
