Debut event at anticipated facility welcomes big numbers in double weekend for Superkarts! USA regional program

 

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 second half of the 2023 California ProKart Challenge was revised due to the arrival of Hurricane Hilary. The fourth stop of the Superkarts! USA regional series in August was scheduled to be a double-round weekend, hosting Rounds Four and Five. Due to the weather issues, Round Five was moved to the upcoming series finale weekend on September 22-24 at the Adams Motorsports Park in Riverside, California.

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.
