In Pixar's Cars 3, which classic race track is associated with Doc Hudson's old racing career?

In Pixar's Cars 3, Doc Hudson's old racing career is associated with Thomasville Speedway.

Thomasville Speedway is a historic dirt track in Thomasville, Georgia, where Doc competed during his earlier racing years. Lightning McQueen visits the area while searching for a way to regain his competitive edge after newer racers begin dominating the Piston Cup circuit.

The track connects Lightning to Doc's past and introduces Smokey, Doc's former crew chief and mentor. Training at the old track helps Lightning understand that Doc's success depended not only on speed but also on strategy, adaptation, and a strong support team.

Thomasville Speedway is fictional, even though the film uses recognizable traditions from American stock-car racing. It should not be confused with real NASCAR venues such as Daytona International Speedway or Talladega Superspeedway. The Piston Cup is the fictional championship contested by Cars characters.
