Welcome to the Thunderhill Open
May 15-17, 2026
We’re doing this our way.
Three days of racing, drifting, music, and motorsport culture —
part Augusta, part Caddyshack, and full throttle.
For one long, loud weekend each year, Thunderhill Raceway Park turns into something bigger than a race event — it becomes a full-tilt gathering of modern grassroots motorsport.
Come race, come hang, come watch it all unfold.

How to get here
The Thunderhill Open takes place at Thunderhill Raceway Park, located just west of I-5 in Northern California.
The track is easily accessed via County Road 306 off Highway 162 and is the single entry point for all attendees — racers, crews, spectators, vendors, and media.
Follow posted event signage on arrival. Plan ahead and arrive only through the main gate.
