The 2026 season for the ProKart Challenge program is set to close out over the October 3-4 weekend, hosting the fifth and final event of the year. The sixth round of the Superkarts! USA regional championship is heading to the K1 Circuit in Winchester, California. 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.

Titles will be on the line across the board with the best five of six championship format for all categories. Three drivers enter the weekend separated by 99 points in the KA100 Senior presented by Hayner Racing Team standings. Stephen Eisert has not won over the first five rounds, however, his consistency has him leading in the chase by 74 points over two-time winner Jake Drew. Archer Eversman is a close third, still seeking that first win on the season as well. Spring Mountain winner Jacob Gulick leads the standings in Pro Shifter presented by Axis Kartsport where the top three are separated by only 46 points. Former series champ Billy Musgrave sits second with two wins while Round Four winner Jesus Vasquez Jr. is in the hunt sitting third in the standings.

The 2026 ProKart Challenge championship finished another step toward crowning this year’s title winners, hosting Round Five of the program at the Spring Mountain Karting Complex. The Superkarts!

KA100 Senior presented by Hayner Racing Team welcomed a new winner on the 2026 season. Texas driver David Ybarra made his debut with fast time in qualifying, posting a 1:13.653 to clear the 25-driver field by nearly two tenths. Qualifying fourth was Archer Eversman, who was able to beat out Round Two winner Matthew Cagle for the win in the Prefinal as Ybarra slipped to fourth behind Gavin McCune. Eversman and Cagle fought for the lead over the first half of the Final before Sebastian Hauser took over. Making his second start on the season, Hauser was able to grab the lead on lap eight and drove away to a 1.6-second advantage for the victory.

The ProKart Challenge will make its second ever visit to the Spring Mountain Karting Complex. The program travels to the Pahrump, Nevada course over the September 12-13 weekend for Round Five of the Superkarts! USA regional championship series.

The program last visited the facility in April 2025, competing on the ‘North’ circuit that replicates the former Las Vegas Karting Center where the SKUSA SuperNationals were held from 1997 to 2001. The 2026 visit will feature the ‘Full Track’ at 1.12-miles and 19 turns, including the long front straightaway that is over 800 feet long.

The penultimate round of the ProKart Challenge puts an emphasis on the championship chases heading into next weekend. Reaching high speeds around the Spring Mountain Karting Complex includes Pro Shifter presented by Axis Kartsport. Multi-time series champion and six-time SKUSA SuperNationals winner Billy Musgrave has two wins in 2026, however, only leads the standings by 16 points over Jacob Gulick. New class winner Jesus Vasquez Jr. is third, only 62 points out of first. Two wins also puts Jake Drew at the top of the standings in KA100 Senior presented by Hayner Racing Team. His lead is 130 points over Stephen Eisert with Round Two victor Matthew Cagle holding third.

The second half of the 2026 ProKart Challenge began over the August 15-16 weekend at Sonoma Raceway. The Sonoma, California circuit welcomed the series for the second of back-to-back trips, hosting the fourth round of the season championship on the ‘Reverse National’ layout. Picture perfect weather greeted the nearly 160 entries across 11 categories for the weekend.

The largest field of the season competed in Sonoma in KA100 Senior presented by Hayner Racing Team, featuring 43 drivers. Stephen Eisert used home track knowledge to grab the fast time in qualifying, earning his third top qualifier honor of the season by posting a 48.480 lap time to edge out Sebastian Hauser and two-time winner Jake Drew by 90 thousandths. Drew led most of the second half of the 12-lap Prefinal, including the final lap to score the win after Eisert was shuffled back on the final lap to outside the top five. Eighth in the race was Chase Hand, runner-up in Round Three at Sonoma. Hand quickly moved up in the 22-lap Final, reaching second by lap eight to sit behind Drew. It was Drew leading the way until the final lap when Hand was able to secure the lead, crossing the line first to claim his first victory of the season. Drew settled for second with Flavio Aquini winning the battle for third over Archer Eversman and Round Two winner Matthew Cagle in fifth.
