When you think of the most incredible achievements in motorsport history, the inimitably versatile Graham Hill and his Triple Crown remains a legendary and unique accomplishment. In more recent times, Michael Schumacher won seven Formula 1 world championships, a feat matched by Lewis Hamilton. Valentino Rossi won seven top-level motorcycle world championships in MotoGP, and Sébastien Loeb won nine WRC drivers’ titles. But while all of those achievements are scarcely believable, they were all accrued in a single category of racing. The Triple Crown, if you didn’t know, is made up of what many consider to be the three greatest motor races (from three different disciplines) in the world – the Monaco Grand Prix, Indy 500 and Le Mans 24 Hours.
