The three were among the contenders at the start of the Final, along with Hand, who climbed to the lead by lap three. Cagle was part of the fight until getting shuffled down the order after the halfway point of the 22-lap event. Hand continued leading until the final lap when Drew was able to go from third to first, winning the drag race to the checkered flag by 15 thousandths.

The ProKart Challenge is returning to action to continue its 2026 campaign with a trip to Sonoma Raceway. The May 23-24 weekend will host Round Three of this year’s Superkarts! USA regional championship program, coming off a two-round event at K1 Circuit in April. This event will mark the second time racing in Sonoma, California since 2017, with last year’s trip being the return of SKUSA competition to the ‘NorCal’ facility. This year’s schedule has the program visiting Sonoma twice, with the second event coming in August for Round Four.
Those two days of racing in April at K1 Circuit helped to shape the early title chases in the 11 categories competing in the 2026 ProKart Challenge. Six-time SKUSA SuperNationals winner Billy Musgrave bested the 21-driver field in both rounds of Pro Shifter presented by Axis Kartsport. Four-time winner in Las Vegas Danny Formal stood on the podium twice on the weekend to sit currently in second for the championship standings – while Jacob Gulick had two top-five runs at K1 Circuit to be third in points. Four drivers are separated by 40 points after two rounds of racing in KA100 Senior presented by Hayner Racing Team. Jake Drew secured the Round One victory and leads the standings by 22 points over Stephen Eisert, who recorded two top five results at K1. Gavin McCune drove to a podium finish in Round Two and is third in the early title chase, just ahead of Round Two winner Matthew Cagle.

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.
A total of 21 drivers battled in the very competitive Pro Shifter class presented by Axis Kartsport that featured multiple drivers at the front throughout the weekend. Jesus Vasquez Jr. was able to secure the opening round fast time in qualifying in only his second class start of his career. A 56.569 set the pace, edging out Jacob Gulick by 59 thousandths. Vasquez fell to third over the opening lap of the Prefinal, allowing Gulick to lead all nine laps. In the opening laps of the 18-lap Final, Gulick fell out of the top five and allowed four-time SKUSA SuperNationals winner Danny Formal to lead the way. Former series winner Keawn Tandon took over the point on lap nine and showed the way until a charging 2025 SKUSA Pro Tour champion Billy Musgrave put himself into the lead at lap 13. From there, Musgrave held off Tandon and Formal to record the victory. Gulick recovered to fourth with Hunter Pickett completing the top five.
