Thousands of elite, amateur and celebrity runners took part in the 32nd London Marathon which covered a 26.2 mile route through the city.
Sunday's race was the last chance for Britain's elite runners to qualify for the London Olympics.
Claire Hallissey is now likely to be named in the Great Britain Olympic team alongside Paula Radcliffe and Mara Yamauchi after completing the race in a new personal best of two hours 27 minutes 44 seconds. The 29-year-old finished 11th in the elite race.
Britain's David Weir equalled Tanni Grey-Thompson's record of six London Marathon wheelchair titles and hailed the British paralympian as a "great role model". Fellow Briton Shelly Woods won the women's wheelchair race.
Prince Harry congratulated elite winners Wilson Kipsang and Mary Keitany. He said: "It's the first time I've been on the finish line to watch it. It's fantastic - a great atmosphere. Everyone's very, very happy."
The event was marred by the death of a 30-year-old woman who collapsed and died while running. Organisers said the woman collapsed at Birdcage Walk, near St James' Park, on the final stretch of the race and died despite receiving medical attention.
Sasha Kenney, 34, hoped to raise more than £2,000 for the NSPCC as she attempted to break the six-hour mark for the quickest hula hooping runner.
For the first time since 2007 runners were able to see the covers off the Cutty Sark which was ravaged by fire. It will officially reopen to the public on Thursday.
James "Arg" Argent, from "structured reality" show The Only Way Is Essex was among a number of celebrities who took part in the marathon.
Shadow chancellor Ed Balls raised £56,000 for Whizzkids, a charity for disabled youngsters, and Action for Stammering Children. He completed the race - his first London Marathon - in five hours and 33 minutes.
The finish line is likely to have come as a welcome relief for runners, marking not only the end of the gruelling course but months of preparation. Participants, many of whom raised thousands for charities, were rewarded with a medal and a foil blanket for their efforts.
