[1] Competitions in show jumping, dressage, eventing, four-in-hand driving, and vaulting are held at the CHIO Aachen.
In addition to the title and following the nomenclature for the tournament, the CHIO has been held under the self-chosen name "Weltfest des Pferdesports" (World Equestrian Festival) since 1992.
Because of the World Equestrian Games a flood light system was installed in the show jumping and in the Hauptstadion.
Eventing and vaulting were added to the CHIO Aachen in 2007, influenced by the World Equestrian Games.
