The 24 Hours of Nürburg is an annual endurance race held at the Nürburgring Nordschleife in Germany. The course is over ten miles in length, and has hosted the event since the beginning. The course also hosted grand prix racing, but it has since been replaced with a much smaller grand prix circuit. That circuit has hosted the German and European Grands Prix. The event was a part of the World Sports Car Championship for many years.
