Lacking evidence from unbiased studies I will go with the medical knowledge on the effect of excessive stress on immature bones and joints.
There's a reason why Arabians are not allowed to race until, they are 3YOs

It all depends on the breeding of the horse, who's handling the horse, what surface they are racing on (hard or soft) and how much excursion they have to use to compete early in their career. If you start on one before their bones have closed you will have problems later on. I personally wish they wouldn't start racing until they are three, but we all know that's not going to happen. Too many owners want those 2 year old checks to cover expenses.
