The 2023 California ProKart Challenge came to a close on the September 22-24 weekend with the final two rounds contested at the Adams Motorsports Park in Riverside, CA. This was a revised series finale for the 19th championship season when Hurricane Hilary forced Round Five in August to be combined with Round Six. The new three-day weekend avoided weather issues, with perfect racing conditions for the drivers wrapping up the 2023 championship program.

The 19th season for the California ProKart Challenge has been put to the test as the program enters the second half of the championship chase. What was scheduled as a three-day, two-round race weekend at the Adams Motorsports Park in Riverside, California over August 18-20 became a shortened two-day, one-round event. Hurricane Hilary hit the southern California region on Sunday, forcing Superkarts! USA to postpone the Round Five action scheduled for that day. Round Four was contested on Saturday, with dry weather greeting the competitors at the historic Riverside, California facility.

The California ProKart Challenge began the second half of the 2019 championship season, hosting Round Four at the Marina Airport Kart Track on July 13-14. The Superkarts! USA regional program took to the home of the Monterey Bay Karters for the two-day event, with practice and qualifying held Saturday, Prefinal and Final held on Sunday. The weather was unseasonably colder, with strong winds dropping the temperature, making the July weekend feel like a winter trip along the Pacific Ocean. The racing was not affected, however, as a number of drivers added to their win totals to help their title chase hopes.
