Online registration for the ballot for next year’s Prudential RideLondon-Surrey 100 sportive is now open at www.PrudentialRideLondon.co.uk.

Taking place on Sunday July 29 2018, the final day of the three-day Mayor of London’s 2018 Prudential RideLondon festival of cycling, the registration will remain open until 80,000 registrations have been received – or until Friday January 5, 2018, if that is sooner.

Entry for the sportive, which takes place on closed roads in London and out into the Surrey Hills, will cost £69 – the same as last year’s price.

More than 100,000 cyclists took part over the weekend of this year’s event, with the festival also including a Free Ride, hand cycling, Brompton racing and the men’s and women’s UCI WorldTour races.

Event director Hugh Brasher said: “The Prudential RideLondon-Surrey 100 is now the most popular sportive in the world with more people applying to ride this event than any other ride on the international calendar.

“More than 100,000 riders have crossed the famous finish line on The Mall in [each of] the first five years of the event, raising tens of millions of pounds for charity on the way."

The route for next year’s event will be announced in due course, once a review of this year’s rides has been conducted.

Online registration for the shorter Prudential RideLondon-Surrey 46 will open in 2018.
