Familiar WeatherTech Championship Slate Set For 2026

SEBRING, Fla. – The International Motor Sports Ass’n revealed its 2026 calendar Thursday at the Mobil 1 Twelve Hours of Sebring, marking an early start on the upcoming season for the second consecutive year.

IMSA becomes the first major motorsports championship to reveal its 2026 schedule.

Stability and consistency continue with the IMSA WeatherTech SportsCar Championship slate, as all 11 venues where the series races in 2025 will carry into 2026.

“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 biggest change to the 2026 WeatherTech Championship schedule sees Road America joining the traditional complement of IMSA Michelin Endurance Cup races: the Rolex 24 At Daytona, Mobil 1 Twelve Hours of Sebring, Sahlen’s Six Hours of The Glen and Motul Petit Le Mans.

The midsummer WeatherTech Championship race at Road America – which will feature Motul as its new title partner – will increase to a six-hour endurance race.

Meanwhile, the penultimate race of the season at Indianapolis Motor Speedway becomes a two hour and 40-minute battle in September 2026, setting the stage for another epic championship showdown.

Aside from race lengths changing at Road America and Indianapolis, the WeatherTech Championship schedule remains consistent from 2025 to 2026.

The season begins with the Roar Before the Rolex 24 mandatory test on Jan. 16-18, followed by the 64th Rolex 24 At Daytona from Jan. 21-25. Next up is the 74th Mobil 1 Twelve Hours of Sebring on its traditional spring weekend, March 18-21.

Both races feature all four WeatherTech Championship classes: Grand Touring Prototype (GTP), Le Mans Prototype 2 (LMP2), Grand Touring Daytona Pro (GTD PRO), and Grand Touring Daytona (GTD).

California hosts the start of the WeatherTech Championship sprint race schedule with annual back-to-back trips to the Streets of Long Beach on April 17-18 for the GTP and GTD classes. The series then continues a few hundred miles up the California coast to WeatherTech Raceway Laguna Seca in Monterey for a two-hour and 40-minute race on May 1-3 for the GTP, GTD PRO and GTD classes.

WeatherTech Championship GTP and GTD PRO competitors then head to the Streets of Detroit for a third consecutive year, May 29-30.

Watkins Glen (N.Y.) Int’l hosts the Sahlen’s Six Hours of The Glen from June 25-28, with all four classes back for the first time since March, before IMSA makes its annual trip north of the border to Canadian Tire Motorsport Park, July 10-12.

At CTMP, LMP2 is the headliner for a third straight year alongside GTD PRO and GTD.

The Road America six-hour race is next from July 30 through Aug. 2, with all four classes, before the GT-only round at VIRginia International Raceway, Aug. 21-23.

All four classes will participate in the final two races of the 2026 season, at Indianapolis Motor Speedway on Sept. 18-20, and the annual Motul Petit Le Mans at Michelin Raceway Road Atlanta, Sept. 30 through Oct. 3.
