X 5K GRAU DE CASTELLO 2026

The 5K Grau de Castello is a 5,000-meter popular road race in Castellon de la Plana, in Spain’s Castellon province. The listed edition was scheduled for a Saturday evening, which makes it a short, accessible race rather than a long-distance event. C.A. Grao Runners organizes the race, and the edition numbering shows a local series with at least ten runnings. The source gives no detailed route map, but the name points to Grau, the city’s maritime district, as the race’s local identity.
