In the year 2004, AP Tri-Val (founded in 1972) and Unión Deportiva de San José de Valderas (born the year before) merged to create Club de Fútbol Trival Valderas. It first reached national competition (Tercera División) five years later. The beginning of the new decade was difficult, as in the 2010-11 and 2011-12 seasons the club had to fight to stay and avoid falling into one of the relegation places in Tercera División. Finally it saved its place in the Spanish fourth tier both times.[4]
