Thousands of spectators lined the streets of Liverpool to watch some of the world's most famous cyclists as the Tour of Britain got under way. The city hosted the Grand Depart, which saw riders set off on a looped circuit around the city centre. Huge crowds gathered and cheered as the riders began eight laps from the waterfront out to Sefton Park and back. The race will go on to follow a further seven stages around the country. Riders taking part include household names Sir Bradley Wiggins and Isle of Man-born Mark Cavendish - who chose to compete despite still recovering from his Tour de France-ending crash in Harrogate.
