IMSA has confirmed the 2025 WeatherTech SportsCar Championship schedule, some five months ahead of its traditional release date, featuring an unchanged calendar to this year.

It is believed to be the first sanctioning body in any motorsports series to have already released its 2025 schedule.

The earlier-than-expected release is understood to help eliminate potential date clashes with other races and series after it released its 2024 calendar last August.

“On behalf of my teammates at IMSA, I am proud to be able to announce our schedule for 2025 at such an early date,” said IMSA President 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.”

As is the case this year, the WeatherTech Championship calendar will feature 11 races, five of them also serving as rounds of the Michelin Endurance Cup.

The season will kick off with the 63rd Rolex 24 at Daytona in late January following the annual Roar Before the Rolex 24, before returning to Sebring International Raceway for the second round of the overall season and Endurance Cup that will feature all four classes in action in mid-March.

Long Beach will again host the GTP and GTD classes only for a 100-minute race, followed by a trip to WeatherTech Raceway Laguna Seca where the two categories will be joined by GTD Pro entries.

The streets of downtown Detroit will feature the GTP and GTD Pro classes in late May for the second 100-minute race of the season, followed the return of LMP2 alongside the three other classes at the Sahlen’s Six Hours of The Glen, which returns to its traditional late June date as the third Endurance Cup round of the season.

This year’s Watkins Glen round has been moved up by one week to avoid a date clash with the CrowdStrike 24 Hours of Spa.

CTMP will again be a LMP2 headline race in 2025, also featuring GTD Pro and GTD in mid-July, with all four classes returning to action in early August at Road America.

Virginia International Raceway will serve as the sole GT-only race on the schedule again, with GTD Pro and GTD in action, followed by the six-hour Endurance Cup contest at Indianapolis Motor Speedway for the Battle on the Bricks in September.

The ten-hour Motul Petit Le Mans will close out the Endurance Cup and overall season on Oct. 8-11, with champions crowned at Michelin Raceway Road Atlanta.
