The second stage of the Tour de France has got under way in York with thousands of people lining the route.
A procession marking the start of the 124-mile (201km) stage began at York Racecourse at 11:00 BST and the race officially started at 11:20.
However, British cyclist Mark Cavendish is out of the Tour after dislocating his shoulder in a fall near the finish line in Harrogate on Saturday.
Large crowds have led to some being turned away from sites on the route.
BBC reporter Dave Edwards at the event's Police Silver Command in York, said officers were asking stewards to redirect people from Oxenhope, Hebden Bridge, Mytholmroyd and High Bradfield because of the huge numbers already at those sites.
The police command centre said it expected more than 50,000 people at the Holme Moss site.
The 197 riders face some of the UK's toughest climbs in Sunday's stage.
One of the focal points for spectators is Holme Moss on the Yorkshire/Derbyshire border - the highest point on the stage at 1,709ft (521m).
The route will pass through Harrogate, Keighley, and Huddersfield before reaching Sheffield at about 16:30, taking in areas made famous by the Bronte sisters and TV series Last Of The Summer Wine.

More than a million people lined the route of stage one of the Tour between Leeds and Harrogate.
Along today's route the riders will tackle nine categorised climbs, which have been given French prefixes, including Cote de Holme Moss and Cote de Jenkin Road, in Sheffield.
The route will also pit the competitors against Cragg Vale - the longest continuous ascent in England.
The first stage of the 2,277-mile (3,664km) race began in Leeds with riders processing to Harewood House where the race was officially started by the Duke and Duchess of Cambridge and Prince Harry.
The peloton passed through towns and villages including Otley, Skipton, Ilkley, Hawes, Leyburn and Ripon before a sprint finish saw Germany's Marcel Kittel claim victory.
