   I am not sure whether the rider or the horse   
   is considered to be the competitor.  But I think   
   they go together; if one of them breaks a leg and   
   must be shot, the other retires from the contest.   
      
   I suppose that a "competition" of this sort may   
   include several scores; time taken, number of   
   fences jumped, grooming, not leaving an additional   
   hazard on the course for the next competitor...
