The Duke and Duchess of Cambridge and Prince Harry will officially open the Tour de France when it begins in Yorkshire later.
Almost 200 riders will be given a royal send-off when they leave Leeds Town Hall and will be greeted by a Red Arrows fly-past when they reach Harewood House.
Up to two million people are due to line the route with many roads closed around the country.
