IMSA has revealed the 11-race 2025 WeatherTech Sportscar Championship calendar during this weekend’s 12 Hours of Sebring.
IMSA shocked both the racing community and fans by revealing the 2025 race calendar for its premier series in March on the eve of its second race of 2024. This was made possible in part by the schedule’s rigidity, which maintains the same venues and order for the current season.
The 11-race 2025 IMSA WeatherTech SportsCar Championship season will feature five endurance races, which together will make up the IMSA Michelin Endurance Cup.
The 10-race Michelin Pilot Challenge program will be back, with one stand-alone race featuring the series at Mid-Ohio Sports Car Course.
The 2025 race calendar for the IMSA WeatherTech Championship and the Michelin Pilot Challenge was revealed by IMSA President John Doonan during a IMSA stakeholders meeting held at Sebring International Raceway ahead of this Saturday’s Mobil 1 Twelve Hours.
“On behalf of my teammates at IMSA, I am proud to be able to announce our schedule for 2025 at such an early date,” John Doonan. “This was made possible through a great spirit of collaboration with our promoter partners, and we are grateful to them for enabling us to make our 2025 plans known today.
“Putting next year’s schedule into everybody’s hands so soon allows fans, competitors and partners to get well ahead in planning for an amazing 2025 season, even with so much of our 2024 season still to come.”
The 63rd Rolex 24 At Daytona will kick off the 2025 IMSA season over the weekend of January 23–26 at Daytona International Speedway as announced last week.
The annual Roar Before the Rolex 24 will take place the weekend before the race on January 17–19, and will once again serve as the opening event of the WeatherTech Championship and Michelin Endurance Cup seasons.
Following Daytona, the 73rd Mobil 1 Twelve Hours of Sebring will take place at Sebring International Raceway from March 12–15. All four WeatherTech Championship classes—GTP, LMP2, GTD PRO, and GTD—will take part in the two opening events.
The WeatherTech Championship will later make its routine journey west to the Acura Grand Prix of Long Beach for its first sprint event, which will include the GTP and GTD classes. GTD PRO will then return to WeatherTech Raceway Laguna Seca in May for the next race.
At the end of May, Detroit, which was reintroduced for 2023, will be returning to the GTP and GTD PRO schedule. The Sahlen’s Six Hours of The Glen will be held at Watkins Glen International on the last weekend of June, with participation from all four classes, following a brief break for the 24 Hours of Le Mans.
Canadian Tire Motorsports Park will be the next to host a race in July with LMP2 as the main event among three classes. The annual WeatherTech Championship visit to Road America in Elkhart Lake, Wisconsin, will take place on July 31–Aug. 3, and all four classes will be back in action.
The only GT-only race on the 2025 schedule will be Virginia International Raceway, with the six-hour Battle on the Bricks at Indianapolis Motor Speedway taking place in September.
The 10-hour Motul Petit Le Mans at Michelin Raceway Road Atlanta, which serves as both the championship race and the Michelin Endurance Cup, marks the conventional climax of the season.
The 2025 IMSA Michelin Pilot Challenge schedule is identical to the WeatherTech Championship schedule with the exception of the two races held in tandem with the NTT IndyCar Series and the inclusion of its main event at Mid-Ohio in June.
