It is considered by many fans of the sport to be the greatest 'single' achievement in cycling. Although mostly it means winning the Giro d'Italia, the Tour de France and the Road World Cycling Championship in one calendar year, occasionally a broader definition is also seen where the victory in the Giro d'Italia can be exchanged for the Vuelta a España; this alternative has gained traction as the Vuelta, historically the least prestigious Grand Tour, has gained in reputation and importance. A hat-trick which did not include the Tour de France and the World title would not generally be considered as the Triple Crown.
