Prix Lupin
The Prix de Longchamps was one of several trials for the Prix du Jockey Club collectively known as the Poules des Produits. The others (listed by their modern titles) were the Prix Daru, the Prix Lupin, the Prix Noailles and the Prix Greffulhe. The Prix de Longchamps was restricted to the produce of mares covered by stallions born and bred in France. It was funded by entries submitted before a horse's birth, in the year of conception.
