Section 163.130 - Number of horses to compete

(a) In the absence of specific conditions, the maximum number of starters in a race shall be limited to the number of starting positions afforded by the association starting gate and extensions thereof. The maximum number of starters is further limited by the number of horses which, in the opinion of the stewards, considering the safety of the horses and riders, can be afforded a fair start. When an entry in a stakes race is denied the opportunity of starting because the number of entries exceed the capacity of the stall gate starting machine and extensions thereof, it will be entitled to refund of nomination or entry box fee or both. In handicap stakes preference will be given to high-weights. In allowance stakes preference will be established by the amount of total winning purses.

(b) The number of starters in an overnight race is limited by the width of the track at the starting post, the maximum number to be determined by the stewards. The number of starters shall be reduced to the proper number by lot or by division, also by lot of the race, at the option of the association.
