Known as the “Marathon de la Route,” the 1963 Liège–Sofia–Liège Rally was a brutal, non-stop endurance test across ten countries without any scheduled rest breaks. The rally forced drivers and co-drivers to stay alert for nearly 100 hours while navigating some of Europe’s toughest roads. The event's reputation for attrition, danger, and extreme fatigue made it one of the most feared and respected rallies in the world.
