The 2026 ProKart Challenge championship hosted its sixth and final round of the season at the K1 Circuit over the October 3-4 weekend. It was the second visit to the Winchester, California facility of the year, opening the 2026 championship and ending the chase at the same location with a different layout each time. The nearly 150-entry paddock was greeted with perfect racing weather over the two days of action to decide this year’s final winners and championship drivers.
