Must look out for that funny back leg walk in future.

Stringhalt!   easier to say than Equine Reflex Hypertonia.

Would this be the reason horse was gelded?

It would have made it difficult to market him as a stallion prospect. So you might as well geld him and make him easier to train.

Screaming - Not sure having stringhalt hampers training. There are quite a few top class stringhalt; we've seen one today. I think one of the American classic winners (Preakness?) was such.

Yes indeed, interesting that never ran as a 2 yo and straight into 12f races as a 3 yo, good middle distance horse its German sire Alderflug, must have watched a bit of goose stepping.

No, I meant a gelding is easier to train than a colt. So, if stringhalt means a colt isn't likely to become stallion, then you might as well geld him/

What I'm trying to say is that stringhalt is a symptom of some sort of underlying nerve problem. You're not going to send your mare to a stallion with a nerve problem which he might pass on to his offspring.

So, without a future as a stallion, regardless of how he performs on the track, your only remaining target is prize money. Off-hand, I think that the Arc is the only race from which a 4yo-plus gelding would be excluded. Other than that, a 4yo-plus gelding would generally be more readily trainable and would win more races and prize money than a 4yo colt
