IMSA has released an unchanged calendar for the 2027 WeatherTech SportsCar Championship season, showcasing stability in its flagship series.

Announced on Thursday, some 317 days before next year’s season-opening Rolex 24 at Daytona, the sanctioning body has yet again become the first motorsport series to confirm its schedule nearly one year in advance.

As has become a tradition since the merger between Grand-Am and the American Le Mans Series, the WeatherTech Championship season will kick off at Daytona International Speedway, beginning with the Roar Before the Rolex 24 on Jan. 22-24, followed by the 65th running of the Rolex 24 at Daytona on Jan. 30-31.

It will be followed by the landmark 75th edition of the Mobil 1 Twelve Hours of Sebring on March 20, before the annual GTP and GTD-only sprint race on the streets of Long Beach in mid-April and first two-hour and 40-minute race of the season at WeatherTech Raceway Laguna Seca in early May, which will feature all classes except LMP2.

GTP and GTD Pro machinery will again be on the streets of Detroit in early June, while all four classes return for the third round of the Endurance Cup season at the Sahlen’s Six Hours of The Glen on June 24-27.

Canadian Tire Motorsport Park will be next up on July 9-11 and will again be a LMP2 headline event with GTD Pro and GTD, followed by the all-skate six-hour Endurance Cup round at Road America on July 29-Aug. 1.

The Michelin GT Challenge at Virginia International Raceway will again be staged for GTD Pro and GTD only on Aug. 20-22, followed by the two-hour and 40-minute Battle on the Bricks at Indianapolis Motor Speedway on Sept. 17-19.

As tradition, the 30th Motul Petit Le Mans will close out the season on Oct. 6-9.

“Announcing our schedule this early in the year, which has now become our tradition, is a testament to the stability of our events and our promoter relationships, and we are grateful to all of our promoter partners,” said IMSA CEO Ed Bennett.

“It also provides an opportunity for everybody involved – from stakeholders and participants to IMSA race fans – to adequately make their plans to attend well in advance.

“Nearly all of our events have seen year-over-year attendance increases the past few years, so it is conceivable that our strategy of announcing our schedules in March is paying dividends.”

IMSA President John Doonan added: “Each season presents an opportunity to build on IMSA’s incredible momentum, and the 2027 schedule represents the very best of our longstanding partnerships and world class venues.

“We are grateful for the continued collaboration with our television partner, NBC Sports, whose support allows us to showcase IMSA’s thrilling, multi-class racing to race fans everywhere.

“We also appreciate the cooperation from our fellow sanctioning bodies as we all work together in good faith to minimize date conflicts and create the strongest possible calendar for teams, partners, and fans.

“The 2027 season is especially meaningful as we celebrate several historic milestones: the 75th running of the Mobil 1 Twelve Hours of Sebring, the 70th anniversary of WeatherTech Raceway Laguna Seca, the 65th Rolex 24 At Daytona and the 30th running of Motul Petit Le Mans.

“These iconic events represent the heart and soul of sports car racing, and we look forward to honoring their legacies with our competitors and passionate fanbase next season.”
