The legendary quartet defining the IMSA summer stretch
It is that time of year when the IMSA WeatherTech SportsCar Championship finds its true rhythm. After the intensity of Daytona and Sebring, the series settles into a summer tour across four historic, natural terrain road courses: Watkins Glen International, Canadian Tire Motorsport Park, Road America, and VIRginia International Raceway. As Roman De Angelis, co-driver of the No. 23 Aston Martin THOR Team Aston Martin Valkyrie, puts it: the racing gets more aggressive and the events come quicker.
The energy surrounding these stops is palpable. Watkins Glen International kicks things off with the Sahlen’s Six Hours of The Glen, where year-over-year ticket and camping sales are hitting their marks. Canadian Tire Motorsport Park is tracking toward its largest crowd in history for the Chevrolet Grand Prix, while Road America is preparing for the expansion of its Motul SportsCar Endurance Grand Prix into a six-hour endurance race in 2026. VIRginia International Raceway rounds out the stretch with the Michelin GT Challenge, reporting rising ticket counts that reflect the growth of motorsports in the region.
Beyond the track, the culture of these venues is defined by their atmosphere. Whether it is the fan engagement at events like the IMSA Preview Party at Seneca Lodge or the tradition of multi-generational camping, these circuits offer more than just speed. With track lengths varying from the 2.459-mile layout at Canadian Tire Motorsport Park to the 4.048-mile sweep of Road America, fans are encouraged to explore the paddocks and find their own vantage points. For anyone heading out to these historic grounds, the advice is simple: arrive early and immerse yourself in the paddock.
