Clásico El Ensayo

The Clásico El Ensayo, also known as the Clásico El Ensayo Mega for sponsorship reasons, is a Group 1 flat horse race in Chile open to three-year-olds, run at Club Hípico de Santiago in Santiago, run over a distance of . The race was first held in 1873, making it the fourth oldest horse race in the Americas (after the Queen's Plate, Travers Stakes, and Belmont Stakes), and the oldest in Latin America.

It is generally considered the most important horse race in Chile, on par with the Epsom Derby, the American classics, the Prix de l'Arc de Triomphe in France and the Gran Premio Carlos Pellegrini in Argentina. It is the first race in the Chilean Triple Crown.

El Ensayo is restricted to only horses that have won at least one race. Provided by Wikipedia
