(September 11, 2020 from Lance Jennings) – Officials with Petaluma Speedway and the United States Auto Club (USAC) have announced the Saturday’s race (September 12) at the Sonoma-Marin Fairgrounds has been postponed. Track promoter Rick Faeth and USAC are working on a make-up date for the event.

“Petaluma Speedway regrettably announces that tomorrow night’s scheduled races are being postponed due to a predicted AQI (Air Quality Index) in excess of 350 reaching a classification level of “Hazardous.” Foremost in this decision is the health, safety, and well-being of the competitors, sponsors, broadcast crew, staff, and the neighborhood as a whole. Petaluma Speedway will continue to operate as a good community partner and we will work with the Sonoma-Marin Fairgrounds Staff to find a potential makeup date for tomorrow’s event,” said Faeth.

The USAC West Coast Sprint Car Series is scheduled to return to Petaluma Speedway on Saturday, September 19th.
