In the summer of 1960, brothers Luis and Ángel Serrano from Bilbao, along with José Luis Sáenz de Olazagoitia from Vitoria-Gasteiz, embarked on a bicycle journey from Vitoria-Gasteiz to Rome. They carried in their saddlebags a petition to declare the Virgen de Dorleta the patron saint of cyclists, which they delivered to the Vatican.

This feat, which has become a symbol of Basque cycling, will be commemorated at the homage event on June 13th in Leintz Gatzaga.
