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.
1962 Mexican Grand Prix
The I Gran Premio de Mexico (or 1st Mexican Grand Prix) was held on 4 November 1962 at the Magdalena Mixhuca circuit, Mexico City. The race was a non-championship event run to Formula One rules and attracted a large entry, including many top teams and drivers. The race was run over 60 laps of the main circuit, and was eventually won by Jim Clark and Trevor Taylor, sharing a drive in a Lotus 25. The race meeting was marred by the death during practice of local driving prodigy Ricardo Rodríguez. The circuit would later be renamed the "Autódromo Hermanos Rodríguez" to honour him and his brother Pedro.
