Cross Internacional de la Constitución is an annual cross country running event which is held in early December in Alcobendas, Spain. The competition was first held in 1982 and began attracting top-level elite distance runners from the 1990s onwards. Hosted by the Club de Atletismo Popular de Alcobendas, the Cross de la Constitución takes place in Parque de Andalucia near the industrial centre in the city. Almost 600 runners took part in the races in 2010.
