The Grand Tours are the three most prestigious multi-week stage races in professional road bicycle racing. The competitions are the Giro d'Italia, Tour de France and Vuelta a España, contested annually in that order. They are the only stage races permitted to last longer than 14 days. The Giro d'Italia, Tour de France, and Vuelta a España are collectively known as the Grand Tours of cycling. The oldest of the races, the Tour, began in 1903, while the Giro first started in 1909 and the Vuelta in 1935. The modern editions of the races all consist of 21 days of racing with two rest days spread throughout race calendar, giving riders at most 63 chances to win a stage in a Grand Tour each year. Winning a stage in a Grand Tour is a significant achievement and winning a stage in each Grand Tour is a rare feat that only 104 riders have achieved in their careers. Fiorenzo Magni was the first rider to win a stage in each Grand Tour with his victory in the stage 7 individual time trial at the 1955 Vuelta a España. The most recent rider to accomplish this task was Rigoberto Urán after he won stage 17 of the 2022 Vuelta a España. Cyclists are ranked on the basis of their total stage wins in the three Grand Tours. When there is a tie between cyclists they are listed alphabetically. The majority of stage winners across the three tours have come from Europe, however, there have been a few non-European cyclists who have accomplished this feat. Colombian Luis Herrera was the first non-European rider to win a stage in each of the Grand Tours when he completed the triple with his victory in stage 13 at the 1989 Giro d'Italia. The first North American to complete this feat is Tyler Hamilton. American Tyler Farrar became the only other North American to do so with his victory in stage 3 of the 2011 Tour de France. Simon Gerrans became the first person from the Southern Hemisphere to win a stage at each Grand Tour with his victory at the 2009 Vuelta a España in tenth leg. Djamolidine Abdoujaparov is the only Asian cyclist on the list. Eddy Merckx, with 64 victories, has won the most stages at the Grand Tours. Mario Cipollini is second with 57, Mark Cavendish is third with 53. Merckx and Cavendish
