A TELEVISION advert is being filmed on Box Hill near Dorking on Thursday and Friday this week.
The commercial, for Halfords, features a large number of colourfully-clad cyclists riding the company's range of bicycles up and down the hill's Zig Zag Road.
A fake bike race finish line has been set up outside the Box Tree Cafe and hundreds of extras and crew members are busily at work in the attraction's hilltop car park.
As a result of filming, Zig Zag Road will be closed from Old London Road to the Box Hill café/car park on both days.
Visitors will still be able to access Box Hill facilities via Box Hill village.
