The California 8 Hours was a sports car endurance race held at WeatherTech Raceway Laguna Seca in Monterey, California, United States from 2017 to 2019 as part of the Intercontinental GT Challenge.[1]
The inaugural edition was open to GT3 and GT4 cars. TCR Touring Cars were added for 2018.[2]
For the first two years, the California 8 Hours served as the season finale of the Intercontinental GT Challenge. In 2019, the date was brought forward to fill the second race of the season. The event was replaced as the American leg of IGTC by the newly created Indianapolis 8 Hours event at Indianapolis Motor Speedway in the 2020 Intercontinental GT Challenge.[3]
Over the three editions of the event, it was broadcast in part on television by CBS Sports Network, and streamed live across the internet.[4] [5] [6]
