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.

The layout for the weekend will feature the ‘Pro Track with Chicanes’, providing a different challenge from the opening double-round weekend that kicked off the 2026 schedule back in April.
