A couple of years ago a horse named St John Castle refused to race the Grand National. The jockey could not get him to move. The horse
had done it the previous year. Perhaps this particular horse thought done it once, got the T-shirt never again. If a horse did not want to do it they wouldn't.
But last year a flat horse broke its leg in a race and also one died on the gallops in Ireland. No fences involved.
If it was banned there would be so much unemployment. The farriers, the grooms, the feed merchants, the saddlers, the vets, all the people involved in the science of racehorses, the trainers so many. The community would also be lost.
