"El Correo" was the promoter of "La Vuelta", the yearly bicycle race around Spain, between 1955 and 1978. However, due to ETA organising attacks on the race from the late 1960s, and increasing disorder around the race in the late 1970s during the Spanish transition to democracy, the Royal Spanish Cycling Federation banned the race from passing through the Basque Country, resulting in "El Correo"'s announcement in January 1979 that it would no longer organise the race. It was subsequently promoted by the sports event company Unipublic and did not return to the Basque Country until 2011.
