After a breakout 2025 season and winning the USAC National Most Improved Driver award, 22-year-old Hayden Reinbold of Gilbert, Arizona, will contest the full 29-race USAC NOS Energy Drink Midget National Championship in 2026. He will drive the Reinbold-Underwood Motorsports No. 19AZ entry and has returned to full-time USAC National Midget competition for 2026. The campaign will open April 24-25 at Kokomo Speedway with the Kokomo Grand Prix.

Reinbold’s 2025 season produced his first USAC National Midget victory in September at Eldora’s 4-Crown Nationals, his 101st national start, where he also recorded his first fast qualifying time. He finished the year 11th in the standings with two top-five and seven top-ten results, and USAC named him the National Most Improved Driver, the first Arizona to earn the honor since Jerry Coons Jr. in 2001.

Reinbold began his USAC National Midget career in 2020 as a 16-year-old at Tulsa’s Port City Raceway. Reinbold-Underwood Motorsports calls the 2026 full-season effort a step up in commitment and ambition, seeking stronger results across the USAC National Midget tour as Reinbold builds on the extra seat time that drove his 2025 improvement.
