Woking town centre hosts cycling races
Major roads in and around a Surrey town centre have been closed to vehicles to create a mile-long (1.5 km) professional cycling race circuit.
Woking is one of 11 towns and cities staging one-day competitions for the Tour Series cycling event, now in its fourth year.
Last year more than 12,000 people lined the streets to watch community and professional races.
The 2012 event began at 12:30 BST with races for local schools and businesses.
The professional races begin at 17:15.
Calendar of events
"Given the nature of the circuit in Woking, the professionals do enjoy the twists and turns and inclines," said Woking Borough Council project manager Geoff McManus.
"We have got so many different people involved now and it is established as part of the cycling calendar and putting Woking on the map."
The Tour Series, launched in 2009, is a calendar of professional cycle races organised by events company SweetSpot, based in Weybridge.
Last year's Woking event was saved by commercial sponsors after the council said it could not afford the £50,000 needed to stage it.
Diversions are in place on Goldsworth Road from the A320 Victoria Way to Coign Church roundabout, Church Road West from Coign Church roundabout to the A320 Victoria Way and the A320 Guildford Road from the Sovereigns Pub to Lockfield Drive.
Surrey is also hosting four London 2012 Olympic cycling events, which will pass through the county on 28 and 29 July and 1 August.
The Olympic cyclists will travel on a large loop through Surrey, taking in Walton on Thames, Weybridge, West Byfleet, West Horsley and Dorking.
The cyclists will ride a 15.5km (9.6 miles) circuit around Box Hill, including the National Trust's Zig Zag Hill.
