GLOBAL TIME ATTACK

May 30–31, 2026

Thunderhill Raceway Park – Willows, California

Global Time Attack makes its debut at Thunderhill Raceway Park with an all-new, multi-discipline motorsports weekend: Thunderhill Circuit Jam.

This is more than a competition — it’s a grassroots motorsports showcase bringing together time attack, road racing, drifting, and track day driving into one action-packed weekend.

What to Expect

Global Time Attack Competition
GTA drivers will take on the East 3-Mile Bypass circuit across two full days of competition. With limited run group sizes and multiple sessions, drivers get clean laps and a safe, high-quality racing environment. [Register Now] KERBZ

SCCA Time Attack & Track Day

Spec Racer Ford (San Francisco Region)
Wheel-to-wheel racing from the Spec Racer Ford group brings close competition and nonstop action to the schedule.

Lone Star Drift
Drift cars take over the West circuit on Saturday, with additional action on the skid pad all weekend — including drift ride-alongs for spectators.

Why Thunderhill

Thunderhill Raceway Park is one of the most respected driver’s tracks in the country, known for its fast, flowing layout, elevation changes, and wide racing surface. The East 3-Mile Bypass rewards precision and commitment, making it the perfect stage for time attack competition.

For Drivers

At Global Time Attack, we do not oversell our run groups.
Driver counts are intentionally limited to ensure:
