1. The PR angle - public perceptions of eventing as "cruel". As a sport it HAS to be doubly careful to make sure that no more ammunition is given to those against, otherwise it risks being banned. For the avoidance of doubt I am very much pro-eventing and want it to look as good as possible. Therefore the FEI has to be seen to act.
2. The partnership between man and horse in competition HAS to be based on the premise that the human is responsible for the welfare of the horse. If there is any doubt about the horse's fitness, it is the rider's duty to pull up, whether it is the Olympics or the local 1'6" horse trials. In fact the duty is heavier on the Olympic rider as they should have the experience to feel the uneven gait. The rider has no right to gamble with the health of the horse, under any circumstances.
Well, I just had a look and THERE IS NO SHOWING forum on there, at least I couldn't find one. But then (I don't want to sound rude or bigotted, but) it is AMERICAN.
Sorry, can't be doing with it. Just my own personal opinion, of course.
There is no Showing forum because we don't have Showing classes in North America in the way that you understand it. There are "hacks" (which just means a class with no jumping) in the hunter divisions and Breed shows (Quarter Horses, Welsh etc.) have "flat" classes but there are no seperate Ridden classes, or Hunters that don't jump, or M&Ms, or even competative lead line classes in our recognised shows. Some smaller, local shows offer versions of such classes and there are "suitable to become" classes for young horses but they are not a discipline per se. There are no non-jumping ridden classes at our big, year end version of HOYS, The Royal Agricultual Winter Fair, except one for young horses and a division for GP dressage horses.
