2026 will mark the Interstate Racing Association’s 60th Anniversary, and with such a historic season the series will have a new look to celebrate the achievement.
The IRA has been honored to represent the Bumper to Bumper brand for over two decades in one of the longest marketing partnerships in motorsports known as the Bumper to Bumper IRA Outlaw Sprint Series. The 2026 edition will have the Auto Value brand joining Bumper to Bumper to give the series a great one-two punch.
“Auto Value and Bumper to Bumper are excited to continue this partnership with the IRA Outlaw Sprints. We consider ourselves the hometown and local favorite for parts and service, which aligns strongly with motorsports,” stated Jim Holik, Director of Marketing at the Aftermarket Auto Parts Alliance, Inc, program headquarters for Auto Value and Bumper to Bumper.
“We’re looking for a great 60th anniversary year, and beyond,” IRA President Steve Sinclair added. “We’re extremely proud to represent these two brands which are a cornerstone in the region in which we compete.”
The Bumper to Bumper / Auto Value IRA Outlaw Sprints are finalizing a schedule that will bring their 60th Anniversary Tour to numerous tracks in a six-state region. The series is proud to release the initial 23 dates of that schedule today, which include returning favorites as well as completely new dates and tracks for 2026.
For the first time, the IRA will head to Maquoketa Speedway in Iowa on April 18, which will serve as the 60th season opener. The Western Iowa bullring is an exciting prospect for the series as this will be the first time winged 410 sprint cars have ever hit the Maquoketa track surface in a competitive setting.
The month of May will be a busy one once again for the IRA in 2026, beginning with a visit to the “Birthplace of the IRA” Wilmot Raceway on May 2. Another Iowa track in Davenport Speedway kicks off a doubleheader weekend on May 8, while the now annual stop at Sycamore Speedway in Maple Park, IL will fill the May 9 date. The familiar doubleheader of Saturday at Plymouth Dirt Track at the Sheboygan County Fairgrounds and Sunday at the historic Angell Park Speedway in Sun Prairie, Wis., makes a return on May 16-17.
The series will return to Wilmot Raceway for the annual Founders Night event on May 23, while the first of two visits to Francis Creek, Wisconsin’s 141 Speedway falls on May 24 to create a Memorial Day weekend doubleheader. May’s racing for the IRA will conclude with a return to the fearsome La Salle Speedway in northern Illinois on May 30.
June opens with a return to the Outagamie Speedway in Seymour, Wis. The series then shifts East to a Michigan double on Friday, June 19 at I-96 Speedway in Lake Odessa, Mich., and the hugely popular event from 2025 at the high banks of Butler Motor Speedway in Quincy, Mich., makes a return on June 20.
After a couple weekends off due to national tour racing in the area, the month of July sees a tripleheader of action beginning with the now fan and driver favorite stop at Mississippi Thunder Speedway in Fountain City, Wis., on July 24, followed by the 26th Annual Jerry Richert Memorial at Cedar Lake Speedway on the 25 and finishing at the Angell Park Speedway on Sunday the 26.
Before the series takes its annual reprieve for the Knoxville Nationals festivities, August will begin with a lone stop at the Plymouth Dirt Track on the first of the month. Racing returns for the series in August on the 22nd and 23rd, with the Kenosha County Fair race at Wilmot Raceway and the annual Corn Fest celebration at Angell Park Speedway.
September will once again be an action-packed month for the IRA. The final month of the season kicks off at 141 Speedway on Saturday, September 5 and is followed on Sunday the 6th by Door County’s The Hill Raceway in Sturgeon Bay, Wis.
The series is extremely proud to once again sanction the Jackson Nationals on September 18-19 at the Jackson Motorplex in Minnesota before wrapping up the 2026 season with the traditional Wisconsin Sprint Car Championships at the Plymouth Dirt Track on Saturday, September 26.
