The 20th season of the California ProKart Challenge will continue on the April 20-21 weekend with a return to the Buttonwillow Raceway Park. The Superkarts! USA flagship regional series kicked off the 2024 season in March with its first visit to the Buttonwillow, California facility and will make another trip for the second round of the championship. This time, competitors will contest the 11-turn, 7/10-mile circuit in the clockwise direction.

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 completed the 2022 season over the October 1-2 weekend, signifying the end of two things. First, the sixth and final round of the Superkarts! USA regional program was contested at the CalSpeed Karting facility. Secondly, the Fontana, California facility hosted its final regional event prior to its closing later this year. CalSpeed has been the site to many Superkarts! USA events during its history, and the final chapter of that story helped to decide this year’s series champions. The backdrop was perfect with weather sunny and warm for the nearly 100 drivers competing over the two-day event on the ‘Classico’ layout.

The California ProKart Challenge traveled to the CalSpeed Karting Center for the lone double-round weekend of the 2022 season. The June 24-26 event at the Fontana, California facility hosted Rounds Three and Four of the Superkarts! USA regional championship program.

The California ProKart Challenge completed the second round of the 2022 season over the May 14-15 weekend at the Buttonwillow Raceway Park. It was the second straight event at the central California facility, with the opening event contested there in April. This time it would be in the clockwise direction around the 7/10-mile circuit. Another chunk of the $70,000 prize package for this season was awarded following the two days of action at Buttonwillow – with all but two drivers earning their first wins of the series this year.

The 2021 season for the California ProKart Challenge came to a close over the October 2-3 weekend with the sixth and final round of the year held at the CalSpeed Karting facility. It was the second visit to the Fontana, California facility in 2021, previously hosting the double-header weekend in June. For the series finale, the near 100 Superkarts! USA regional entries took to the ‘Classico’ layout to decide this year’s series champions.
 

The California ProKart Challenge hosted the penultimate round of the 2021 season on the September 11-12 weekend at the Willow Springs International Raceway. The Rosamond, California facility has been the site of many Superkarts! USA regional program events in the past, including both the famed Streets of Willow course and the karting circuit. The two-day event for Round Five of the 2021 championship program was held on the nine-turn, 6/10-mile kart track in the counter-clockwise direction.
