Its worth noting that Synchronised was not injured in its fall at Bechers Brook but was brought down at a later fence which it jumped without being forced to,and was brought down by another horse. Horses are running and jumping machines, and although I believe that every care should be taken its worth making the point that these magnificent animals do carry on running and jumping without a jockey on board. The number of runners is, IMO, the real issue as 40 horses charging at full tilt will only result in falls and interference. Rduce the maximum to 25 or 30 and see the result
