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.[1] Hosted by the Club de Atletismo Popular de Alcobendas,[2] the Cross de la Constitución takes place in Parque de Andalucia near the industrial centre in the city.[3][4] Almost 600 runners took part in the races in 2010.[5]
The men's elite competition is held over roughly 10 km, while the women elite runners compete over approximately 6 km.[6] The exact race distances of the courses on the park's looped circuit vary from year to year, thus no course record is kept. The women's race was previously about 5 km but has been around 6 km since 1999.[7] The race day's events include nine categories of competition: six are youth races by age group, short and long course races are held for senior athletes, and a separate veteran's race is also held for older runners.[2]
