iRacing: Indy 6 Hour 2025 Endurance Challenge

iRacing Indy 6Hrs

Every September, sim-racing fans have an unmissable date: the Indy 6 Hour, an endurance race that captures the essence of long-distance racing and that irresistible team spirit that keeps us coming back.

It’s not just about driving for six hours; it’s an experience that blends strategy, teamwork, and pure passion for competition.

The stage couldn’t be more iconic: the Indianapolis Motor Speedway – Road Course, a layout that breathes racing heritage. While Indy is often linked to ovals, its road course delivers a unique challenge: technical corners, long straights, and that unmistakable atmosphere only a place with such legacy can offer.

Racing there even virtually makes you feel like you’re part of something bigger.

Classes on track

  • GTP & HYP
  • LMP2
  • GT3 (IMSA)

That blend of lightning-fast prototypes and more “grounded” GT cars produces memorable battles. Whether you’re at the sharp end or in the heart of the pack, there’s always action around you.
