The Lone Star Le Mans is an endurance sports-car race held at Circuit of The Americas in Austin, Texas, serving as the U.S. round of the FIA World Endurance Championship. The event features multi-class prototype and GT competition on COTA’s 3.41-mile, 20-turn counterclockwise layout—highlighted by the steep uphill Turn 1—and draws major manufacturer teams and global endurance drivers to compete for championship points. It is notable for the traffic management challenges of multi-class racing and its role as a premier international motorsport event in Austin.
