The most striking number in De Aguiar's early record is his performance at Dundalk, Ireland's all-weather track that races year-round under floodlights. Eleven of his 16 winners have come there, from 51 runners — that means his horses win at Dundalk at a rate of around 1 in 5, noticeably better than his overall figures. For a new trainer, finding a track where your horses consistently perform is enormously valuable. Dundalk runs almost every week, which gives De Aguiar a reliable pipeline of opportunities, and he is clearly using it well.
The partnership with jockey Donagh O'Connor tells a similar story. Seven wins from 41 rides together works out at roughly 1 in every 6 — and when you narrow it down to their combined record, that is a meaningful chunk of everything De Aguiar has achieved so far. In racing, a trainer and jockey who genuinely click can make the whole operation look better than the sum of its parts. O'Connor clearly understands what De Aguiar wants from his horses, and that relationship looks like one to follow.
What makes this profile worth reading is not just the numbers — it is the pace of it. Most trainers spend years quietly grinding before any pattern emerges. De Aguiar has been at it for less than twelve months and
