All horses shall parade, carrying their weight and wearing their equipment, from the paddock to the starting post. Any horse failing to do so may be declared by the stewards. No lead pony leading a horse in the parade shall be ridden so as to obstruct the public's view of any horse which is to race, except with the permission of the stewards or their delegate who shall report the granting of such permission and the reasons therefor to the Board.
