We love circuits. Circuit de la Sarthe, is a semi-permanent race course chiefly known as the venue for the 24 Hours of Le Mans. Still comprising private, race-specific sections of track in addition to public roads which remain accessible most of the year, its present configuration is 13.626 kilometres (8.467 mi) long, making it one of the longest circuits in the world. The 'infernal roundabout' holds a special place with all sport car racing fans. We love Le Mans.
