This year marks the 100th anniversary of the Le Mans 24-Hour Race – you may have heard of it – an endurance event held on an 8.4-mile track in the French countryside. Its venue, Circuit de la Sarthe, combines public roads and private track that weave through the woods on the outskirts of town, and the race features prototypes and sports cars – vehicles with huge speed differentials, all fighting to win their respective classes while dodging each other day and night.
