I don't have a problem with jumps racing done properly but in this country it's not or rarely done properly. Those other sports you mention Lee have evolved rapidly in recent years to protect themselves from accusations of horse abuse from animal welfare quarters. Dressage banned a controversial training method known as "Rolkur" even though the dutch used it with particular success to win many a gold medal. In dressage ANY trace of blood on a horse from a spur rub or in the mouth results in elemination from the competition. And don't think the judges won't do it, a Dutch rider who was favoured for the individual silver medal, and the dutch team the gold, was eliminated at the last world championship during her test because her horse displayed a trace of blood in its mouth. It was determined after the test by the vets that he had bitten his own tongue.
Whip rules in showjumping have changed, previously a horse was able to refuse 3 times in a competition before it was eliminated, and the rider could punish it on each occasion freely with the whip. Now a horse may only refuse twice before elimination, and a rider may only strike the horse 3 times with the whip on the first occasion and not at all on the second. Actually most riders will only strike a horse now twice if it refuses.
They are still in the rule book but virtually no one programs any of the old events in showjumping where the size of the fences kept increasing until the horses failed to be able to jump them. No one wanted to see horses tested to the max any more, and showjumping evolved into a competition where it was more about a horses education then his absolute ability to jump a big fence. I maybe on my own here but I would like to see harness racing evolve likewise to the point where people can be satisfied to see a horse win without being concerned about how fast it ran. That it is the calibre of the opposition that you defeated, not how fast you ran that determines the merit of the performance.Who here would say that Black Caviar is not a champion yet she has not once run a track record in her career. And I have no doubt that if a race track manager produced a surface on which she could have smashed the track record Peter Moody would have refused to start her.
Eventing removed the roads and tracks and steeplechase from the cross country in all but a few four star events throughout the world to protect the horse from the fatigue related falls that were occurring. Only the very best competitors in the world are accepted into a four star event these days with extremely strick qualifying conditions. And all events now are one fall at a fence or on the flat in the cross country and you are eliminated.
Pretending that people don't care about horse welfare or the use of performance enhancing drugs in harness racing is folly
