IMSA reveals 2026 WeatherTech Championship schedule
IMSA announced the 2026 WeatherTech SportsCar Championship calendar this afternoon as part of the build-up to the Mobil 1 Twelve Hours of Sebring. The schedule for next year features no changes in the number of dates and venues; however, two key race format tweaks have been made.
Road America's IMSA SportsCar Weekend has been shifted to a six-hour race and will become part of the Michelin Endurance Cup, while the race at Indianapolis Motor Speedway will revert to a two-hour, 40-minute sprint contest. These two races will maintain their existing calendar slots -- with Road America on the Aug. 2 and the shorter race at Indianapolis set to be held on Sept. 20.
The 64th annual Rolex 24 At Daytona will open the season on Jan. 24-25, followed by the 74th annual Sebring 12 Hours on March 21.
The sprint season begins with IMSA's visit to Long Beach on April 18, followed by the weekend in Laguna Seca on May 3, and then the Detroit Grand Prix on May 30.
After Le Mans, IMSA returns with the Six Hours of Watkins Glen on June 28. The series will visit Canadian Tire Motorsport Park (Mosport) on the July 12, with the LMP2 class headlining the CTMP round once again.
VIRginia International Raceway hosts its annual GT-exclusive sprint on the Aug. 23, before Indianapolis in September. The season will close with the 28th annual Motul Petit Le Mans at Michelin Raceway Road Atlanta on the Oct. 3.
“The collaboration between IMSA and our event and promoter partners has allowed us to reveal our 2026 calendar at such an early date for a second consecutive season,” said IMSA President John Doonan. “This collective spirit will help our paddock and fans in preparation for next season, even as we have the majority of the 2025 season still to run.”
The schedule for the Michelin Pilot Challenge series has also been shown off. Consistency and date equity carry through to the 2026 season there too, with a 10-race calendar for Grand Sport (GS) and Touring Car (TCR) class competitors. Pilot Challenge will continue to run alongside the WeatherTech Championship at every round aside from street course races in Long Beach and Detroit.
The series also steps into the headliner spotlight at Mid-Ohio Sports Car Course with a four-hour endurance race on June 5-7. That four-hour race joins the Daytona four-hour race, with the remaining eight rounds continuing at two hours.
The schedule flows from Daytona to Sebring, Monterey to Mid-Ohio, then alongside WeatherTech Championship rounds at Watkins Glen, Canadian Tire Motorsport Park, Road America, VIR, Indianapolis and Michelin Raceway Road Atlanta.
