The 2021 season for the California ProKart Challenge is set to close out next weekend (October 2-3) at the CalSpeed Karting facility. The Fontana, California circuit outside the Auto Club Speedway is hosting the sixth and final round of the championship chase. The program contested a double-round weekend here back in June, with this single-round event set to battle around the ‘Classico’ layout in the counter-clockwise direction. Action in Fontana will be the final step of the 2021 championship program, with drivers taking the best five of six rounds toward the final standings.

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.
