Prix Royal-Oak
Under British National Hunt racing (i.e. Steeplechase) rules, to minimize health and safety risks, nearly all participating horses are gelded. On the other hand, in other parts of Europe, geldings are excluded from many of the most prestigious flat races including the Classics and the Prix de l'Arc de Triomphe (with an exception being the French classic Prix Royal-Oak, open to geldings since 1986). In North American Thoroughbred racing, geldings, if otherwise qualified by age, winnings, or experience, are allowed in races open to intact males. The same applies in Australia.
