Well, thanks for that, Cantoris - I'm usually shot down in flames over this subject, but it's not the galloping that generally kills them - although fractures may well start on the flat and end up snapping on landing concussion. I would not want to see any jumping at any time of the year on Firm, full stop. I don't think it's a fair ask when we know that chasing (and to a somewhat lesser degree hurdling) can result in many horses being BD, sometimes multiply, and can hit the deck in a shoulder-shattering crunch, when they have been enjoying the race otherwise. With Soft, there are still cracks and crunches - really, only Soft to Heavy or even Heavy - which we saw a lot of this last winter - tends to ensure that more get round without bone-snapping, since speed is not a factor.
The firmer it is, the faster they go. That means that instead of lumbering up to the open ditch out of soggy ground, they're zinging it, with not just a much faster smash into the ground, but no chance for the ground to absorb some of the impact and to allow the horse to slide. It's a dumb joke that there is much pontificating about the unsafeness of Polytrack (or the perception of it being so, since no-one's yet hurdled on it) as it doesn't permit horses to slide once they hit the ground. Good is pretty much the equivalent surface, while GF and certainly F is just dead, like a lot of the animals which have the unfortunate happen to them. You might as well put jumps racing over Polytrack and see whether it results in the same amount of casualites or not.
GF/F - no absorption of impact, no chance to slither or slide, much more speed to the races. As far as setting up the chance of your horse not surviving a fall, it's brilliant.
As for the watering business, I'm sure that they could conserve their Euros if they didn't water all the track, but concentrated on the areas up to 70 feet from the landing side of the jumps, making them softer to land in. Yes, it would be an experiment of sorts, but it would provide for a more shock-absorbent landing, a couple of strides, and away. If the horse fell, it would provide enough area for a potential slide, rather than just a heavy dead smack into the ground.
However, that quite possibly contravenes some sort of watering policy laid down in IBHA rules, as far as I know!
Tracks can be very water-intensive and in these days of supposedly conserving resources, this would be one possible solution to those intent on running their heavier jumping horses on harder ground. It's rarely the bits between the jumps that does them in, so Clerks should perhaps reflect their cost concerns and say that there are one or two cheaper solutions. Their problem is that they have to start declaring the state of the ground so early and, given the vagaries of our weather, probably assume that as soon as they water, rain will come in drenching bucketloads, so don't want to start calling 'Good', only to find 'Soft, Heavy in Places' five days later.
Have you e-mailed the Clerks at Wexford and Punchestown to find out why they didn't continue their watering programme right up to racing? It'd be interesting to find out why they called things off and let the ground dry out so. As a well-respected connection in racing, they should have the courtesy to reply to you with a decent explanation.
