Amaury Sport Organisation (ASO) was set up in September 1991 within the Amaury group, publisher of the sports daily L'Équipe. It brought together the Société du Tour de France, its cycling arm, and Thierry Sabine Organisation, which runs the Dakar Rally.
It later expanded: the Paris Marathon in 1998, Paris-Nice in 2002, the Open de France golf in 2003 and the Critérium du Dauphiné in 2010. In 2008 it also took a stake in Unipublic, organiser of the Vuelta a España.
In sailing, ASO bought the Tour de France à la voile from Éditions Larivière in 2012. It is based in Boulogne-Billancourt.
