The inaugural RideLondon cycling event is expected to raise between £3m and £5m for charities, according to its organisers.
Four cycling events are taking place in London this weekend as part of the initiative, including the London-Surrey 100 – a 100-mile bike ride taking place on closed roads in and around the capital on Sunday 4 August. Organisers said that about 5,000 of the estimated 25,000 places in the London-Surrey 100 had been offered to charities.
The event is being managed by the London and Surrey Cycling Partnership, a joint venture between the organisers of the London Marathon and the Tour of Britain.
The other events taking place over the weekend are FreeCycle, a family-friendly cycling event taking place on traffic-free roads; the London-Surrey Classic, a race for professional road cyclists; and a series of Grand Prix races for professional women, junior and hand cyclists.
A spokeswoman for RideLondon said in a statement that it was impossible to give an accurate prediction of how much money would be raised for charity in the first year, but estimated that the amount raised would be between £3 and £5m.
