logo for IMSA Sportscar Endurance Challenge
2025 Season 1 - Races every other Saturday at 4 & 15 GMT and Sunday at 0 GMT, 20 GMT
Just like its real-world counterpart, iRacing’s IMSA SportsCar Endurance Challenge allows you to get behind the wheel in both the LMP3 and GT4 classes for some more approachable multi-class road racing. In this series, though, you’ll race in extended events rather than just sprints! Races are held every other week starting in Week 1.
