The International GT Endurance Series (IGES) is a competitive GT endurance racing championship built around professional organization, fair competition, and immersive endurance racing.

Featuring Pro, Pro-Am, and Am classes, IGES gives drivers the opportunity to compete against racers of similar skill levels across an eight-round championship. Events range from three-hour races to full 24-hour endurance classics at iconic circuits around the world.

Every championship round features live commentary, live stewarding, and professional race control, while drivers and teams battle for the Drivers’, Teams’, and Manufacturers’ Championships.

From strategy and pit stops to driver swaps and late-race battles, IGES is building a community for racers who want endurance competition that feels organized, competitive, and worth showing up for.

Pitmark Racing Co. is proud to partner with IGES and support the people putting in the laps, building the community, and leaving their mark on endurance racing.
