Dubbed the 'home of British motorsport,' Silverstone is arguable the most well-known venue on the British GT calendar.

Silverstone also hosts the third round of the FIA World Endurance Championship in its 2018/19 Super Season.
Located near Marseilles in the South of France, Circuit Paul Ricard was constructed in 1969 and featured the impressive 1.8km Mistral Straight.

Located in the Belgian Ardennes, Spa-Francorchamps is widely regarded as one of the finest race circuits in the world and plays host to the fly-away round of the British GT Championship, the opening round of the FIA World Endurance Championship as well as the 24 Hours of Spa.
