The capital-based cycling event RideLondon, which has raised more than £66m for good causes since 2013, is to continue for a further decade.
A statement from London Marathon Events said it had been given a contract by the Mayor of London and Transport for London to run the event between 2021 and 2030.
Prudential RideLondon has established itself as one of the largest annual mass-participation charity fundraising events.
More than 100,000 cyclists took part in seven RideLondon events over the weekend, which includes mass-participation rides over 19, 46 and 100 miles, FreeCycle, which enables people to ride around traffic-free roads in central London, and the Brompton World Championships final.
The other two events are races for professional riders.
The contract has been awarded after a competitive tendering process managed by TfL on behalf of Sadiq Khan, the Mayor of London.
A spokesman for London Marathon Events declined to confirm how much the contract was worth.
Will Norman, London’s Walking and Cycling Commissioner, said RideLondon was "the world’s greatest festival of cycling".
He said: "I’m delighted that London will continue to host this fantastic event."
Next year’s RideLondon will take place on 15 and 16 August.
