Spanish Grand Prix
The first Spanish Grand Prix in 1913 was not actually run to the Grand Prix formula of the day, but to touring car rules, taking place on a 300-kilometre road circuit at Guadarrama, near Madrid, on the road to Valladolid.
Formula One
Six of the original seven races took place in Europe; the only non-European race that counted towards the World Championship in 1950 was the Indianapolis 500, which was held to different regulations and later replaced by the United States Grand Prix. The F1 championship gradually expanded to other non-European countries. Argentina hosted the first South American Grand Prix in , and Morocco hosted the first African World Championship race in . Asia (Japan in ) and Oceania (Australia in ) followed, and the first race in the Middle East was held in . The nineteen races of the season were spread over every populated continent except for Africa, with ten Grands Prix held outside Europe.
Some of the Grands Prix, such as the oldest recognised event the French Grand Prix, pre-date the formation of the World Championship and were incorporated into the championship as Formula One races in 1950. The British and Italian Grands Prix are the only events to have been held every Formula One season; other long-running races include the Belgian, German and French Grands Prix. The Monaco Grand Prix, first held in 1929 and run continuously since 1955, is widely considered to be one of the most important and prestigious automobile races in the world.
