The International Chiba Ekiden was an annual team road running competition held in Chiba, Japan in late November. The marathon relay race, or ekiden as it is known in Japan, is one of the prominent annual races of its kind. The competition is split into six legs which combine to make up the marathon distance of 42.195 km. The Chiba Ekiden was first held in 1988 and featured separate competitions for both men and women. Since 2007, each competing country selects three men and three women for their team. The legs are divided as follows: 5 km (men), 5 km (women), 10 km (men), 5 km (women), 10 km (men), and 7.195 km (women).
