Classical Dressage is an Olympic discipline based on the harmony between rider and horse, through which, a series of movements are made, of great difficulty, indicated following a pre-established program in a text called reprise. The movements executed by the horse, although natural for the horse, require large doses of training and preparation of the binomial. The horses move laterally, turn on themselves, change their feet at the gallop and execute airs of extreme difficulty and beauty such as Passage and Piaffe among others, always observed by the judges who score them inside a 20m x 60m track.
