But the Briton was forced to watch from the commentary booth today as her women only mark of 2:17:42 was erased from the history books by the courageous Keitany who claimed a third London Marathon title to go with her three NY crowns. Her pace in the first half suggested a finish time faster than the outright world record of 2:15:25, set by Paula Radcliffe in 2003. That's why I slowed the pace.
The men's elite and mass start races were started by Prince Harry and The Duke and Duchess of Cambridge.
"It was becoming tougher and tougher".
Meanwhile, Daniel Wanjiru completed the course in 2hrs 5min 48sec to add to his success at the Amsterdam Marathon previous year.
The six-time Paralympic gold medallist beat reigning champion Marcel Hug of Switzerland in a sprint finish to win for the first time since 2012.
Britain's David Weir won a record seventh London Marathon men's wheelchair title - and afterwards called it his "best victory ever".
President Uhuru Kenyatta on Sunday led the nation in congratulating London Marathon winners Mary Keitany and Daniel Wanjiru terming their triumphs "a great win for Kenya".
The retired British athlete still remains a world-record holder. We pushed and the sun was coming up and the day was lovely. Bekele boasted the fastest personal best of the field with his 2:03:03 from last September's Berlin Marathon.
However, Wanjiru stepped pressed on as Bekele seemingly went out of gas in the last 600m to let the Kenyan reign. Since the diagnosis, and losing two good friends from cancer recently, it's become even more apparent in my life, that i'm lucky and life is for living. "I'm really proud of you".
"There were times when perhaps I thought I'd never win again but this race is so special to me and I wanted this so badly".
Ms Jakhu said: "After learning about how extremely small a charity LAM is, I felt raising funds for it could make a real impact".
Ms Garcia said: "I needed to find a charity Liz, Amy's mum, would think was appropriate".
Kenyan runners have won the men's race eight times in the past decade but a strong Ethiopian triumvirate is tipped for success with last year's champion Eliud Kipchoge and runner-up Stanley Biwott both absent.
The date for the 2018 London Marathon is yet to be officially confirmed but it's a safe bet that it will fall on Sunday 22nd April. The London Marathon is ranked in the top six of events of its kind in the world and is a huge spectacle.
