The story began in the 1950s when a group of local mountaineers and hikers decided to recover the tradition to climb to the Sanctuary of Sant Joan de Penyagolosa from Castellón. This challenge and a project to restore ancient roads and trails resulted in the Sender de la Lluna Plena (Full Moon Trail), GR-33, which connects the city of Castellón with the peak of Sant Joan de Penyagolosa, at 1814 meters of elevation.
In the 1990s it went initially from a two-day hike to a single day, which marked the birth of the Pujada a peu Castelló-Sant Joan de Penyagolosa (Castelló-Sant Joan de Penyagolosa Foot Race). Then in 1998, the MIM Marató i Mitja (63K) was conceived. From then until now, almost 20 years’ experience of organizing sports events through mountain paths of ancient pilgrimage routes steeped in history and tradition have been added up.
