It began on April 10 and lasted for five days. In 1852 it was renamed the Union Race Course. In 2009, the Horseplayers Association of North America introduced a rating system for 65 Thoroughbred racetracks in North America. Of the top Fifteen, New Orleans Fair Grounds was ranked #12, behind Evangeline Downs in Opelousas, Louisiana, which was ranked #6.
