Thunderhill Raceway Park, nestled in the Sacramento Valley near Willows, California, stands as a premier motorsports complex, celebrated for hosting the United States’ longest automobile race, the 25 Hours of Thunderhill. With its expansive facilities, Thunderhill offers an original 3-mile track (Thunderhill East), a 2-mile addition (Thunderhill West), and the option to combine both for a formidable 5-mile road course, the longest in America.
The versatility of Thunderhill extends beyond traditional racing; the venue is adept at accommodating a wide array of events, from drifting and go-karting to corporate functions and even weddings. This adaptability makes Thunderhill not just a racetrack but a multifaceted event space capable of hosting a diverse range of activities.
Owned by San Francisco Region Properties, Inc. and operated as a wholly independent entity under the San Francisco Region Sports Car Club of America, Thunderhill boasts a rich history of motorsport dedication. Since its inception in 1993 as a 1.9-mile, 9-turn track, Thunderhill has undergone significant expansions, including a 1997 extension to its current 3-mile layout and the 2014 addition of Thunderhill West.
This continuous evolution reflects Thunderhill’s commitment to providing an exceptional racing and event experience, earning it the affectionate nickname “Thunderschleife” in homage to the legendary Nurburgring Nordschleife. Thunderhill Raceway Park’s blend of challenging tracks, comprehensive facilities, and a broad event portfolio cements its status as a cornerstone of California’s motorsports landscape.
