Brussels Acerta Ekiden Relay is the biggest relay marathon in the world. In 2012 over 1300 teams composed by 6 runners each have registered.
The term "Ekiden" has japanese origins, and originally referred to a post-horse or stagecoach which transmitted communication by stages. The first ekiden race was sponsored by the Yiomiuri Shimbun in 1917, and was run over three days between the old Japanese capital of Kyoto and the modern capital of Tokio, a distance of 508 km, to celebrate the anniversary of the moving of the capital to Tokio.
