Cyclists have pushed off from the start in the Prudential RideLondon mass participation event and are heading into Surrey.
Unfortunately, adverse weather has forced the organisers to change the route.
The course has been shortened from 100 miles to 86 miles, cutting the section that included Leith Hill and Box Hill.
Surrey County Council chairman David Munro is set to send the world’s best cyclists on their way in the professional race at 1pm.
The RideLondon-Surrey Classic then heads back to the capital via Dorking and Esher for a finish on The Mall.
With thousands of spectators set to line the course, organisers have provided local homes and businesses with the information they need to prepare and make the most of the events.
The latest on the weather can be found by visiting the Met Office website.
Surrey County Council Cabinet Member for Community Services Helyn Clack said: “Sunday promises to be a special day for cyclists and spectators alike.
“All the information people need to plan ahead and make the most of the events in Surrey is available on the Prudential RideLondon website. We’d urge everyone to use it, check the county council website or follow @SurreyTravel on Twitter for regular updates on the day.”
