Rolling Thunder 2026

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.
