What we do know is where Perfect Heir comes from. The sire is Perfect Power, a horse that was electric over short distances at two and went on to win at the highest level, so there is natural speed in the bloodline. The dam — Perfect Heir's mother — is by Selkirk, a stallion associated with horses that tend to be tough, reliable, and effective on a variety of ground conditions. It is a combination that could produce a sharp, precocious type who takes to racing early, though with any debutant, that remains to be seen.
The trainer is Andrew Balding, based at the famous Kingsclere yard in Hampshire — a place with a long and distinguished history in British racing. Balding's team has been in outstanding form this season, sending out 204 winners, which is a remarkable number and a sign that horses leave that yard fit, well-prepared, and ready to run. When a stable is operating at that level, it gives even a first-time runner a degree of credibility. Balding knows what he is doing, and horses making their debut from Kingsclere in good form are worth watching closely.
Beyond that, the honest answer is we simply do not know yet. Today is the beginning of the story, not a chapter in the middle of it.
