MOORESVILLE, N.C. — While Interstate Batteries High Limit Racing continues to experience exponential growth, the Midweek Series which started it all remains at the heart of the operation.
As the mini-series within a series returns for a fourth season in 2026, Roto-Rooter, the country’s largest provider of plumbing repair and sewer and drain cleaning services for 90 years, has once again partnered with Interstate Batteries High Limit Racing as the title sponsor of the Roto-Rooter Midweek Series.
“Roto-Rooter is proud to now be in our third season of partnership with High Limit Racing and Kyle (Larson),” said Thad Reinhard, President of Roto-Rooter Corp. “Since our very first High Limit event in April 2024, we’ve seen High Limit grow exponentially, and with that, the exposure and promotion of Roto-Rooter. The vast network of Roto-Rooter technicians across the country not only get to feel at home when they attend a High Limit event, but they also get to see their company showcased on FS1 five times this season and on the NASCAR Channel for an additional race. The constant desire to be the best in the business directly aligns with our values at Roto-Rooter and we look forward to continuing that success for years to come.”
New in 2026, the Roto-Rooter Midweek Series is comprised of all standalone single-day events from Monday through Thursday on the Interstate Batteries High Limit Racing schedule – giving the series 15 races at 14 tracks in 11 states for the mini-series.
Of the 15 Roto-Rooter Midweek Series races, five will be live on both FloRacing and FS1 as sprint cars continue to garner network television coverage with Interstate Batteries High Limit Racing. The opener at New Mexico’s Vado Speedway Park on March 24 and the finale at Indiana’s Kokomo Speedway on September 23, along with Eagle Raceway (April 21), Grandview Speedway (May 19), and Red Cedar Speedway (June 3), are the five Roto-Rooter Midweek Series events on FS1. In addition, the Roto-Rooter Midweek Series event at Santa Maria (California) Speedway on August 20 will air live on both FloRacing and the NASCAR Channel.
“Roto-Rooter has been a great partner to High Limit and it’s great to have them return for a third season with us,” said Kyle Larson, co-founder of Interstate Batteries High Limit Racing and defending NASCAR champion. “The midweek series is how High Limit got started and it’s cool for me and Brad (Sweet, High Limit Racing co-founder) to have Roto-Rooter see the value in the midweek events.
“I’m looking forward to getting back into a sprint car and running as many Roto-Rooter Midweek Series events against these guys as possible.”
Nebraska’s Eagle Raceway is the lone track with two Roto-Rooter Midweek Series dates, the first being the April 21 race on FS1, and the second being the beloved $50,000-to-win FK Rod Ends Eagle Nationals on June 9 – the crown jewel of the Roto-Rooter Midweek Series.
The Roto-Rooter Midweek Series champion will receive a $25,000 bonus following the Driven2Save Lives Midweek Mayhem finale at Kokomo Speedway on September 23. Drivers are not required to complete the full Interstate Batteries High Limit Racing schedule to be eligible for the Roto-Rooter Midweek Series prize money. The 15 Roto-Rooter Midweek Series events do, however, count toward the overall Interstate Batteries High Limit Racing championship.
