In road bicycle racing, a Grand Tour is one of the three major European professional cycling stage races: Giro d'Italia, Tour de France, and Vuelta a España. Collectively they are termed the Grand Tours, and all three races are similar in format, being three-week races with daily stages. They have a special status in the UCI regulations: more points for the UCI World Tour are distributed in Grand Tours than in other races, and they are the only stage races allowed to last longer than 14 days, and these differ from major stage races more than one week in duration.
