Hello, Elle!
I'll miss Mag, all right!
She will now become a broodmare.
The very good horses are retired and have a good life.
Kauto Star, the Gold Cup winner, took up dressage when he retired!
I suspect some horses may not be wanted when they retire.
A sad end indeed, lies ahead for some of them.
Younger horses will replace them, and the stable girls will be broken hearted when the lorry comes to take away a horse they have lovingly tended.
Unfortunately, racing is not all about winner's enclosures.
