Rolling Thunder 2026

Thunderhill Raceway Park

About this event

58th Season Finale, Thunderhill Raceway Park
(103dB sound limit event)

The racing is chill, the weather is exquisite, everyone gets lots of track time and the Saturday dinner is delicious, fun and memorable.  Opt for a full Friday of testing and then at least four sessions (but sometimes six!) on the weekend and you will return home ready for a winter's rest! There will be midday Mechanical Picnics on both weekend days and maybe even a street car session.  This year we are thrilled to have the Porsche Club of America’s Golden Gate Region racers join us.  A welcome addition to this racer weekend.  Come see how great racing at the hill can be and help grow this event. 

Fees: CSRG requires all drivers be either a Full Racing Member of CSRG, or a Single-event Member.  Our friends from other racing organizations may choose the Single-event Membership for $100.
