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.
Montjuïc circuit
In 1968, Montjuïc was selected as the venue for the Spanish Grand Prix, which had been held at the Jarama circuit in Madrid, with the inaugural Grand Prix being held there on May 4, 1969. The variable character of the anticlockwise course (with one half slow and the other very fast) made setting the cars up correctly a challenge.
