Perhaps we had better redefine what was
observed. If you define "overridden" as not fit to continue he was not
being overridden. What was observed was a horse that was taking awhile to
come down in pulse (say 15 minutes, well within the allowed parameters), and at
the trot out acting more tired than an average horse should at that point in the
ride.
If, as almost all riders do when requested by the
vet, he had slowed down for the second loop the horse would have finished
fine. It is never possible to have a crystal ball and stop everyone from
going into the gray area of running a horse faster than the horse really should
that day, but slower than the pace that would cause a crash.
