The 2025 schedule of HSR sprint and endurance events has been expanded to seven race weekends and includes the all-new HSR Classic Endurance Championship. The four-event series will include the new HSR Classic 10 Hour at Michelin Raceway Road Atlanta, which joins the existing HSR Classic tribute races at Daytona International Speedway, Sebring International Raceway and Watkins Glen International.

The season begins on March 7-9 at the HSR Classic Sebring 12 Hour and concludes at the same Florida facility for the HSR Pistons and Props, December 5-7.
