Geistige Behinderung
During the 1980s, there were 8 classes for cerebral palsy competitors, 3 classes for competitors with visual impairments, 9 classes for competitors with ambulatory issues and six classes for Les Autres athletes. Intellectual disability athletics classifications existed by the 1984 within the context of the Special Olympics. In some cases, one intellectual disability class existed with events broken down by age in order to allow equal competition for runners. Some of these races were held in Canada and disability classes competed during able bodied events.
