Castellón Half Marathon

The Castellón Half Marathon is the oldest road running event in the province of Castellón and one of the most iconic races in Spain. First held in October 1984, it has grown into a landmark event in the national running calendar, attracting thousands of athletes every year to the streets of Castellón de la Plana.

Organised by the Unió Atlètica de Castelló (UAC), the race has built a strong legacy over more than four decades, becoming a symbol of consistency, community, and sporting passion. From its first winners in 1984 to today’s international field, the event continues to grow in scale and prestige.

The course is a fast, urban 21K designed for performance, personal bests, and accessible racing conditions. Its flat profile and city layout make it ideal for both competitive athletes and recreational runners looking for a well-organized half marathon in Spain.

With increasing participation and record-breaking editions, the Castellón Half Marathon stands out as a key early-season race, combining tradition with modern race organization.
