The 20-turn, counterclockwise circuit takes advantage of the naturally undulating landscape, including an intimidating 133-foot hill at Turn 1 that must be seen in person to be believed. It is home to the only Formula 1 and MotoGP races in the country — the UNITED STATES GRAND PRIX and Red Bull Grand Prix of The Americas — and has played host to ESPN's X Games, the FIA World Endurance Championship, IMSA WeatherTech SportsCar Championship, Pirelli World Challenge and more.
