The Racing Arabian encompasses purebred Arabian horses bred and trained specifically for competitive racing, whether on flat tracks or in endurance events spanning distances up to 100 miles. These horses represent the athletic branch of the world's oldest and most influential breed, selected for speed, stamina, and competitive drive while maintaining the distinctive Arabian type and beauty.
The Arabian Horse Association (AHA) serves as the primary registry for purebred Arabians in North America, maintaining records for over one million horses. The AHA formed through a merger between the Arabian Horse Registry of America and the International Arabian Horse Association, consolidating record-keeping and promotion under one organization. All purebred Arabians must be DNA tested and qualify to registered parents for AHA registration.
The Arabian Jockey Club (AJC) specifically governs flat racing for purebred Arabians in North America. Organized around 1959, Arabian racing has grown steadily with sanctioned races held at tracks throughout the United States. The Darley Awards, named for the Darley Arabian who founded one of three Thoroughbred foundation sire lines, honor excellence in Arabian racing annually.
Recent genetic research has revealed concerning findings about some racing Arabian bloodlines. Studies have detected Thoroughbred DNA in significant percentages of horses used for flat racing, with some individuals carrying up to 62% Thoroughbred genetics despite being registered as purebred Arabians. The Heritage Arabian Racing Club (HARC) has excluded certain stallion lines proven to carry Thoroughbred ancestry, and some registries now mark descendants of these lines as ineligible for purebred registration.
