The headline number, though, is 63 top-level wins. These are not ordinary races — Class 1 is the peak of the sport in Britain, the races that define careers and fill highlight reels. Sixty-three of them, at iconic venues including Cheltenham, Kempton Park and Sandown Park, tells you that De Boinville is not merely a competent jockey who piles up winners in lesser company. He consistently shows up and delivers on the biggest days. As recently as this spring he landed top-level wins at three separate venues — Newbury on 7 February, Ascot on 14 February, and Cheltenham on 10 March 2026 — a remarkable cluster of high-profile successes in the space of just a month.
No profile of De Boinville would be complete without Constitution Hill. The pair have raced together 13 times and won 10 of them — a success rate of 10 from 13 that borders on the extraordinary. In jump racing, where the ground, the field, and the obstacles conspire to make certainty impossible, that kind of consistency with a single horse speaks to something deeper than luck. It suggests a genuine understanding between horse and rider, the sort of partnership that fans remember long after specific race results fade.
His relationship with trainer Nicky Henderson tells a similar story. From 167 races together, De Boinville has ridden 40 winners for Henderson's yard — winning roughly 1 in every 4, or 24% of the time. That is not the casual arrangement of a jockey picking up spare rides. It is a sustained, high-performing alliance between one of Britain's most celebrated training operations and a jockey trusted to carry its best horses into the biggest moments. Four years into his career, with 273 winners and 63 at the very top level, De Boinville already looks like one of the defining riders of his generation.
