More than 40,000 people participated in the 39th London Marathon on Sunday, with many runner targeting over 80 Guinness World Records.
Tennis ace Andy Murray fired the starting gun at this year's event as the participants descended on the British capital for the race, the BBC reported.
The marathon has raised 1 billion pounds since it started in 1981, according to race sponsors Virgin Money.
Event director Hugh Brasher said: "No other mass participation event comes anywhere near this kind of fundraising.
"We would like to thank every runner, supporter, donator, charity, volunteer, sponsor, spectator, staff member and everyone else who has contributed to this wonderful total."
Speaking about the funds raised for good causes, London Mayor Sadiq Khan said: "This is an astonishing achievement and my congratulations go to everyone involved in making the London Marathon such a world-renowned fundraising success - helping millions of people over the last 38 years."
