The 2026 IMSA WeatherTech SportsCar Championship concludes Saturday at Road Atlanta with Petit Le Mans, a 10-hour race that will decide titles across GTP, LMP2, GTD Pro, and GTD.

Jack Aitken leads the GTP standings by 147 points over Laurin Heinrich, with 350 for victory, keeping the championship open despite his cushion. His season form is profiled in the Jack Aitken IMSA GTP analysis.

LMP2 is even tighter. Jeremy Clarke and Tom Dillmann hold a four-point lead over George Kurtz and Alex Quinn, making execution and reliability decisive across traffic-heavy stints.

GTD Pro is led by Corvette duo Nicky Catsburg and Tommy Milner, with Connor De Phillippi and Neil Verhagen 47 points back, keeping strategic options wide open. Key permutations feature in the GTD Pro finale Petit preview.

In GTD, Philip Ellis and Russell Ward lead, while Robby Foley and Patrick Gallagher sit 37 points behind. Caution timing and driver time management could swing the outcome.

A 54-car entry underlines the challenge: 11 GTP, 11 LMP2, 14 GTD Pro, and 18 GTD. The full roster appears in the Petit Le Mans 54-car grid overview.

Headline contenders include the #60 Meyer Shank Racing Acura ARX-06 for Tom Blomqvist, Colin Braun, and Scott Dixon. BMW M Team WRT’s #24 features Dries Vanthoor and Sheldon van der Linde.

The #31 Whelen Cadillac V-Series.R pairs Jack Aitken with Earl Bamber, maintaining Cadillac’s late-season momentum.

Track action ramps up from Thursday. VP Racing SportsCar Challenge runs 1:05–1:55 p.m., followed by Mazda MX-5 at 2:10 p.m., then Porsche Carrera Cup from 5:20–6:05 p.m. ET.

Friday brings more VP Racing and MX-5 running, then the IMSA Michelin Pilot Challenge from 11:35 a.m. to 1:40 p.m. WeatherTech qualifying follows at 2:15–3:35 p.m., before Carrera Cup at 3:50–4:35.

The main event starts at noon Saturday and runs to 10:30 p.m. Coverage is available on YouTube, Peacock, IMSA.TV, and USA Sports, ensuring accessible, uninterrupted viewing.

With titles unresolved, risk management, stint length optimisation, and traffic discipline will define the race. Caution timing and night running typically compress margins at Road Atlanta.
