Entries Open for 2026 WeatherTech Championship

Continuing a recent trend of opening entries shortly after the Road America race weekend in early August, IMSA opened its entry application process today for the 2026 IMSA WeatherTech SportsCar Championship season.

Entries are open for all full-season, partial-season and Michelin Endurance Cup race events.

Both the quality and quantity of WeatherTech Championship entries have been on display in recent years, with many events running at or near capacity grid size. In recent years, there have been more entries than those that can be accommodated.

“The enthusiasm surrounding the IMSA WeatherTech SportsCar Championship continues to grow, and we’re once again expecting more entry applications than we can accommodate,” said IMSA President John Doonan.

“It’s a testament to the strength of our platform and the commitment of our teams, manufacturers, and partners. As we open entries for 2026, we remain focused on delivering a competitive and compelling championship for all stakeholders and especially IMSA race fans.”

The deadline for those entering the Roar Before the 24 and Rolex 24 At Daytona events is Tues., Oct. 7. If entries fill prior to that date, IMSA will close entries at that time.

The event and driver confirmation deadline comes a week later, on Tuesday, Dec. 2.

The 2026 WeatherTech Championship kicks off with the Roar Before the Rolex 24 on the weekend of Jan. 16-18, followed the next week by the season-opening Rolex 24 At Daytona from Jan. 21-25.
