The Egyptian owners are running a big risk keeping the first Triple Crown Winner in 37 years on the track. Losses, or worse, an injury that requires the horse to be put down, are possible. Balanced against the 10s or 100s of millions of dollars to be made in stud fees. Just plain stupid.
Racing is not all about the money. They are trying to prove the greatness of their horse. In much of the horse world glory is more important than money. Even in the lower levels of the show world proving your horse is a good one is what matters. I know. Have some really good horses but no money-lol.
