IMSA has revealed its 2027 schedules for the IMSA WeatherTech SportsCar Championship and IMSA Michelin Pilot Challenge.

The WeatherTech Championship again features an 11-race season with some subtle changes, while the Michelin Pilot Challenge again features 10 races but will include a second headlining event in 2027. All 11 venues that have hosted the series for the past several seasons are returning in 2027.

The season will start with the 65th running of the Rolex 24 at Daytona, slated for the weekend of January 28-31, on the 3.56-mile Daytona International Speedway circuit. Daytona again kicks off the "36 Hours of Florida," and will be followed by the milestone 75th running of the Mobil 1 Twelve Hours of Sebring on March 17-20.

Both races again will be part of the five-race IMSA Michelin Endurance Cup season and will include all four classes--Grand Touring Prototype (GTP), Le Mans Prototype 2 (LMP2), Grand Touring Daytona Pro (GTD PRO) and Grand Touring Daytona (GTD).

The 30th Motul Petit Le Mans at Michelin Raceway Road Atlanta in Braselton, Georgia, will close out both the 2027 WeatherTech Championship and Michelin Endurance Cup seasons on October 6-9.

The two-class IMSA Michelin Pilot Challenge---featuring the Grand Sport (GS) and Touring Car (TCR) classes--will be the weekend headliner for two of its 10 event weekends in 2027 as the series tops the bill in a return to Lime Rock Park in addition to being the main attraction with its annual four-hour race at Mid-Ohio Sports Car Course.
