The ProKart Challenge will make its second ever visit to the Spring Mountain Karting Complex. The program travels to the Pahrump, Nevada course over the September 12-13 weekend for Round Five of the Superkarts! USA regional championship series.

The second half of the 2026 ProKart Challenge began over the August 15-16 weekend at Sonoma Raceway. The Sonoma, California circuit welcomed the series for the second of back-to-back trips, hosting the fourth round of the season championship on the ‘Reverse National’ layout. Picture-perfect weather greeted the nearly 160 entries across 11 categories for the weekend.

The opening two rounds of the 2026 Superkarts! USA ProKart Challenge were held over the April 24-26 weekend at K1 Circuit. The Winchester, California facility welcomed the SKUSA regional program for rounds one and two of action to begin the six-round championship schedule. A total of 11 categories began the title chase for the 2026 season with five drivers able to leave the opening weekend with two wins toward their point total.

The opening weekend for the 2023 California ProKart Challenge took place over March 11-12 at the Buttonwillow Raceway Park. Nearly 100 competitors participated on the weekend at the California facility with two full days of action for the first event of the six-round championship program. The 7/10-mile circuit in the counter-clockwise direction welcomed nine drivers earning their first victories on the season at the Superkarts! USA regional program.

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.
