Charities are being invited to apply to become the official charity partner of the London Marathon in 2020.
The event sponsor, Virgin Money, said in a statement that it would choose a charity that had, or was looking to start, a project or programme that encouraged people to participate in sport, or which used sport to make a difference.
The 2020 race will be the 40th London Marathon and will also be the 10th year of Virgin Money's sponsorship.
The successful charity will receive 250 guaranteed race places in the 2020 event, 50 in 2021, 25 in 2022 and 10 in 2023.
It will also become Virgin Money's corporate charity of the year for 2019/20 and benefit from staff fundraising initiatives. It will receive advertising space in the official marathon magazines.
Charities have until 9 February to apply.
The nominated charity for the 2018 event is the Teenage Cancer Trust. The selected charity for 2019 has yet to be revealed – the organisation is usually named in the days after the previous year’s race.
Hugh Brasher, event director for London Marathon Events, said: "I am delighted that Virgin Money has chosen sport to be the beneficiary of the 40th running of the London Marathon.
"Our co-founders, my father Chris Brasher and John Disley, were huge advocates of the power of sport in transforming lives for the better."
A Virgin spokesman said nominated charities did not always declare how much they raised. He said: "The 2015 event saw Cancer Research UK raise a record £3.2m excluding Gift Aid for the new Francis Crick Institute."
