In just one week, the California ProKart Challenge returns to action and hosts the lone double-round weekend of the season. Competitors from all over the west coast will converge on the CalSpeed Karting Center facility in Fontana, California during the June 24-26 weekend for Rounds Three and Four of the Superkarts! USA regional program.

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.
