IMSA 2026 Calendar: Discover the complete schedule of the 11 rounds of the American championship

As usual, the 24 Hours of Daytona opens the season from January 21st to 25th, followed by the Roar from January 16th to 18th. The season concludes at Road Atlanta with Petit Le Mans from September 30 to October 3.

Only one change is to be noted in this calendar: the penultimate race of the year, Indianapolis, reverts to a two-hour and forty-minute sprint, as it was for the inaugural edition in 2024. Five races are still scheduled in Endurance Cup since Road America takes over this six-hour format, during the first weekend of August.
