The Indianapolis 500 is not just one of motorsport's biggest events, it also forms part of the legendary Triple Crown, an achievement many drivers consider the hardest challenge in global racing.
The Triple Crown traditionally consists of winning the Monaco Grand Prix, the Indianapolis 500 and the 24 Hours of Le Mans. The three races represent completely different forms of motorsport, forcing drivers to master Formula 1 street circuits, high-speed oval racing and endurance competition.
Because of the vastly different skill sets required across all three events, completing the Triple Crown has become one of racing's rarest accomplishments.

Graham Hill remains the only driver in history to officially complete the Triple Crown. The British driver won the Monaco Grand Prix five times during his Formula 1 career, claimed victory at the Indianapolis 500 in 1966 and finally secured the 24 Hours of Le Mans in 1972.
Hill's achievement has stood alone for decades largely because modern motorsport schedules and specialisation make crossover appearances increasingly difficult.
Several major drivers have come close without finishing the full set. Fernando Alonso remains the most famous modern example after winning Monaco and Le Mans before repeatedly targeting the Indianapolis 500.
Alonso's Indy 500 appearances with McLaren became one of the biggest crossover stories in modern motorsport history because Formula 1 drivers rarely leave the championship during their careers to compete in oval racing.
Juan Pablo Montoya and Jacques Villeneuve also moved within touching distance after winning both Monaco and the Indianapolis 500 during their careers.
The Indy 500's place within the Triple Crown reflects the race's global status beyond IndyCar itself. Winning at Indianapolis requires a completely different driving style compared to Formula 1 or endurance racing.
Modern Formula 1 drivers face additional obstacles because the Monaco Grand Prix and Indianapolis 500 traditionally take place on the same day. That scheduling conflict has made Triple Crown attempts far more complicated for current competitors.
The rise of specialist racing programmes has also reduced opportunities for drivers to switch disciplines regularly, especially with Formula 1 calendars continuing to expand.
McLaren remains one of the few organisations strongly linked to the Triple Crown because the team has won all three events across its racing history.
Even so, Graham Hill's achievement continues to stand alone more than 50 years later, highlighting why the Triple Crown remains one of the most respected accomplishments in motorsport.
