The Olympic Climb
Box Hill’s famous zigzag road became known worldwide when it featured as the decisive climb in the 2012 Olympic road race. The ascent rises roughly 120 metres over 2.5 kilometres via a series of tight hairpin bends cut into the chalk escarpment of the North Downs. Starting from the roundabout at the foot of the hill near Burford Bridge, the gradient averages around five per cent but kicks up sharply on several of the bends. At the summit, riders are rewarded with panoramic views south across the Weald and the chance to refuel at the National Trust café.
The full loop extends the climb into a satisfying circular route through the villages of Mickleham, Westhumble and Brockham before returning to Dorking. The roads are well surfaced and popular with cyclists, so drivers are generally accustomed to sharing them. Weekend mornings see large groups tackling the climb, and the route is a staple of many Surrey sportives. For those wanting to extend the ride, it links naturally to Ranmore Common and Leith Hill.
Route Details & Practical Tips
The loop begins and ends in Dorking, where there is ample parking at the mainline station or the Meadowbank car park. Head north on the A2003 to Burford Bridge, then take on the zigzag ascent. From the top, continue along the ridge road before descending via Headley Lane to Brockham Green, a picturesque village with a pub stop at The Royal Oak. Return to Dorking via the Brockham lanes.
The route is well signposted and largely on quiet roads apart from a brief section on the A24 near Burford Bridge, where care is needed. Mechanical support can be found at Dorking Cycles in the town centre. The climb is rideable year-round, though the hairpins can be slippery in wet conditions due to leaf litter in autumn.
