About the race

Trail Trincheras XYZ is a trail race in Jérica (Castellón), in the Alto Palancia, that follows the trenches of the XYZ line, a Spanish Civil War defence now taken back by the pine forest, with views of the Sierra de Espadán, La Calderona and Penyagolosa. The Z is 28 km (+1,228 m), the Y 19 km (+834 m), the W 18 km and the X 12 km (+616 m), a fast one for a first trail; the Y, Z and W are in the UTMB Index. On the Saturday the Trinchera Vertical climbs 385 m in 4.8 km to the Alto de Sayas, and the Combinada adds it to the Y. It is organised by the Club Deportivo Chafaaliagas and the town council.
