The Triple Crown of Motorsport is an unofficial motorsport achievement, often regarded as winning three of the most prestigious motor races in the world in one's career:
For eleven years (1950–1960) Monaco and Indianapolis were part of the FIA World Championship of Drivers (now synonymous with Formula One) but in 1961 Indianapolis was dropped from the World Championship series. In 1987 the Monaco race date was changed to be about two weeks later than earlier years. Since then both it and the Indianapolis race have been held on the same day making it impossible for one driver to compete in both races the same year.
Graham Hill is the only driver to have completed the Triple Crown. 17 drivers in motorsports history have competed in all three legs of the Triple Crown and have won at least one of the events.Juan Pablo Montoya is the only active driver to have won two of the three events.
An alternative definition 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.
Endurance sports car racing has its own Triple Crown which features Le Mans and has added the 24 Hours of Daytona and the 12 Hours of Sebring. This crown has been won by several drivers, namely A. J. Foyt, Hans Herrmann, Jackie Oliver, Jacky Ickx, Al Holbert, Hurley Haywood, Mauro Baldi, Andy Wallace, Marco Werner and Timo Bernhard. Many drivers have come close to winning the crown with 2nd-place finishes in the third event, such as Ken Miles (who was famously denied the win by a technicality at the 1966 24 Hours of Le Mans), Mario Andretti (Le Mans 1995) and Allan McNish (Daytona 2012).
