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.
Mexican Grand Prix
The Mexican Grand Prix was first held on 4 November 1962 at the Magdalena Mixhuca circuit. The circuit was the first international racetrack in Mexico and was built within a park in the center part of capital city of Mexico City. The race provided unique challenges for racing, standing at 2,240 (7,340 ft) above sea level, as well as the long, 180-degree, lightly banked and fast Peraltada corner that finishes the lap, in addition to being a bumpy racetrack from actively shifting soils beneath the circuit. The Mexican Grand Prix of this period was always the season finale Grand Prix, held in late October.
