Prix d'Amérique is a harness race held at the Hippodrome de Vincennes in Paris, France. The race takes place on the last Sunday of January every year, and has been doing so since 1920, with the exception for the years 1940-1941 when it was cancelled due to World War II. It was established to thank the US for the help given to France in World War I.[1] It is widely considered the most prestigious harness race in the world.
