They may live in a guilded cage and have fancy names, but their lives arent great. Kept in most of the time, turning out would be too risky if they got injured
Come of it Monty, stop spreading ignorance. Most TB broodmares have a great life with turnout, the young racestock are turned out for 2 years in large natural herds (which is more than beef cattle get) and have a lovely adolescence. Racehorses are exercised 6 days a week and turned away for large periods of time, and many racehorse trainers do turn out. Which again is more than many livery yards do in winter. And indeed showjumping and dressage yards.
Plenty of horses will refuse to run and jump. We just dont usually see them on racecourses. They will have been dispatched long before that, either put down (the lucky ones) or sold on to be tranported to foreign abbatoirs or to foreign tracks or into a spiral of neglect in unsuitable homes
So exactly the same as might happen to any horse bred for riding then.
The wastage in the industry is such that there would need to be a race horse retirement venue in every town, but I dont seem to have seen them
I'm pretty sure that if every poster on this thread donated £50 or £100 to the Retraining of Racehorses Charity instead of salving their consciences due to a once a year tv event, they could make quite a difference. You of course will have done your part no doubt by buying an ex-racehorse off a trainer, as most of them will let them go very cheaply to a good home, and they are usually quite easy to ride, being traffic proof (I worked 5 summers in a row as a stable lass in racing during university holidays).
that includes not knowingly putting them into dangerous situations
Your average amateur riding going round a cross country course is far more dangerous.
Personally, I think encouraging the import of young over-worked dressage horses from the Continent with hocks that are sure to spavin is far worse. But my major animal concerns are live transportation of animals long distances to slaughter and halal killing.
