The last thing we need, as racing fans, is to see accusations of the Coliseum raised, where animals are pitted against man-made difficulties to see whether they're 'brave' enough to survive. And what of the horses that can't complete? Does that make them cowards? I don't like the gladiatorial tone that race analyses often take, although I'm guilty of falling into those cosy cliches myself. Yes, they're brave - or perhaps just stupid - to keep going when their natural instinct would be to stop. Why do they? I've no idea. But if an animal is at the point of exhaustion when it gets to the line, I think we've gone too far in exploiting it for our pleasure or gain, just like spectators at the Roman circus.
We can drive ourselves to exhaustion all we want - we have the brains to make that choice. Driving any animal, not gifted with human intellectual notions of choice, to exhaustion is plain wrong, whether it's a brutalized Cairo carthorse, a brickfield donkey in India, or a well-maintained racehorse in the UK. Any animal used by us deserves humane treatment, and I think we're close to losing that in the rush to stage races at any cost, so as not to lose income.
Racehorses are bred to race, of course, but that doesn't mean that we should force that issue when commonsense and human decency should indicate otherwise.
(And before someone rushes in with "they stop if they can't go on" - that's not borne out by the number which need rehydrating offstage, or which grind to a walk to get home. They're supposed to gallop, not wobble, across the finish line. DEANO'S BEENO got smart long before his connections did - he began his own revolt against being hauled out again and again, and even the "he loves it" doughty KINKEEL drew the line yesterday. So, fine, eventually - after a vast amount of mileage on the clock - some will stop themselves. And is that something that adds to the pride or lustre of the sport?)
