What informal three-race motorsport crown includes the Indianapolis 500? The Triple Crown of Motorsport. It links the Indianapolis 500 with the 24 Hours of Le Mans and the Monaco Grand Prix.

The three races represent different challenges. Indianapolis is a high-speed oval race for open-wheel cars, Le Mans is a 24-hour endurance contest in France, and Monaco is a tight Formula One street race through Monte Carlo. Their formats, cars, and governing series differ, but all are historic, internationally recognized events.

The crown is informal rather than an official championship with a governing body or standardized trophy. It is a later motorsport comparison inspired partly by horse racing’s Triple Crown and by the prestige of winning major events in different disciplines.

Graham Hill is the only driver to have won all three races. His achievement came through victories at Monaco, Indianapolis, and Le Mans between 1963 and 1972. Winning any one of the three is a major accomplishment; completing the set remains exceptionally rare.
