The broader career numbers back this up. Eleven wins and 17 places from 32 races, with a win rate of around 1 in every 3 — that is exceptional. Most horses at this level are doing well to win 1 in 5. Stuart Williams, who trains Quinault out of Newmarket in Suffolk, has had a strong season with 67 winners sent out from the yard, and Quinault represents the kind of top-end performer that defines a stable's reputation. Jockey Marco Ghiani has been a key part of the story too — the pair have won 4 of their 10 races together, which works out at 40%, or roughly 2 in every 5 times they go to post.
The prize money tells you exactly what level this horse operates at. Four Class 1 wins in 2024 alone — at York, Chester, and Newmarket — plus another at the top level this June, is a remarkable sequence. Class 1 races are the elite end of British racing, and Quinault has won 4 of 14 starts at that level, a 29% win rate against the very best. There is also a noticeable preference for slightly soft ground — wet, slower conditions suit this horse, with 2 wins from just 3 races on it, a 67% conversion rate that is almost startling.
The current form line does require a mention. Quinault has not won in the last six races, finishing 11th most recently. After the heights of 2024, that represents a dip, though the most recent York win in June 2025 sits inside that six-race stretch — so the sequence needs reading carefully rather than dismissed as a slump. A horse that has won at the top level as recently as eleven months ago, at a track it clearly loves, on ground that can come in its favour at any time, is never truly out of the conversation.
