The young horse is in the care of James Owen, a Newmarket trainer whose yard has already sent out 205 winners this season, a sign of a stable that knows how to prepare its runners properly. Owen's operation clearly turns out horses ready to race, which counts for something when a debut is imminent. What Ozone Friendly will make of the racecourse itself, though, remains an open question — first runs can reveal a horse's temperament and natural ability in ways that even the best breeding and training cannot fully predict beforehand. This is where potential meets reality, and where a debut winner becomes a genuine talking point, or where a stumble teaches everyone a lesson about patience. Either way, it will be worth watching.
