Juan Pablo Montoya and Fernando Alonso are the only active drivers to have won two of the three events . </P> <P> An alternative definition, as espoused by Triple Crown winner Graham Hill, and Jacques Villeneuve replaces the Monaco Grand Prix with the Formula One World Championship; Graham Hill is also the only driver to have accomplished this, winning the F1 Drivers' Title in 1962 and 1968 . </P>
