Zig Zag Road is a tarmac (pristine and smooth) road winding its way up North Downs in Surrey, in the South East of England.
The road climbs up to Box Hill, a mountain pass at an elevation of 224 m (735 ft) above the sea level. The road is asphalted, steep and very narrow and is a popular test of fitness for cyclists. This narrow road called the zig zag on the face of the hill shows a a steady climb of 120 metres (390 ft) over 2.5 kilometres (1.6 mi) and, although on a much smaller scale, has been likened to the Alpe d'Huez in the French Alps. The Zig Zag Road featured prominently in the 2012 Summer Olympics cycling road race events: in a mid-race circuit at Box Hill, the men climbed the road nine times and the women twice.
