That's quite an interesting point of view there, JAP, from the Sceptical Punter. He does briefly mention trainers getting horses (in particular 2 y.o.'s) ready early vs those who bring them only later, but surely by now we all know that the Hannon yard is virtually a 2 y.o. factory, where, while they'll all be out early, some may never come out again, and he's not given to waiting out slow-growers/late learners, and the like. They're expected to bounce out, win, and try not to fracture any bones before they win a couple more times and may never be seen out at 3, let alone 4. At that stage, if they're still sound, they're often away to other trainers and the 'coming on for a run' starts all over again. I can't think of the Hannon set-up as ever bringing horses back, because once they're busted, they're gone for good.
Conversely, there are other trainers who don't believe in battering the babies, and treat their youngsters individually, thus they won't all be required to 'come on for a run' as the instructions may well be to just take it steady and try out a different placing/riding tactic.
He's right about the inane prattle, though. What horse doesn't 'come on' for a run, unless it's unfit and shouldn't be running? They're supposed to be athletes and, like athletes, it's only by going at full competitive pace that they truly stretch their skills, mental and physical.
