The summer stretch of IMSA WeatherTech SportsCar Championship action intensifies with the run of four straight historic, natural terrain road courses starting with next weekend’s Sahlen’s Six Hours of The Glen at Watkins Glen International. The race is also the third of five IMSA Michelin Endurance Cup rounds.
Among the 54 cars in four categories, a number of endurance-specific entries and drivers return, including Mobil 1 Twelve Hours of Sebring GT class winners Manthey and Af Corse USA, both with tweaked lineups. There’s also a handful of new faces dotting the four classes.
The sixth of 11 weekends in the 2026 season marks Round 6 for Grand Touring Prototype (GTP), Round 3 for Le Mans Prototype 2 (LMP2) and Round 5 for both Grand Touring Daytona Pro (GTD PRO) and Grand Touring Daytona (GTD). Here’s what else you need to know heading into the weekend in upstate New York:
