Her overall numbers tell a solid story. In the last 12 months she has sent out 24 winners from 250 runners — that is roughly 1 in every 10, a respectable rate for any trainer, let alone one still in the early years of building a yard. Across her career she has reached 118 winners in total, a figure that speaks to consistent, professional operation rather than the occasional lucky strike. The most recent highlight came on 16 May 2025, when she landed a top-level race at York, one of the most demanding tracks in the country. Before that, wins at Kempton in December 2024 and Newmarket in July 2024 showed she can operate across different venues and different times of year.
One pattern worth noting is what happens when the weather turns. On wet or muddy ground, Chapple-Hyam's horses win 6 from 32 races — that is 19%, or roughly 1 in every 5. Compare that to her overall rate of 1 in 10, and it is clear her yard has a genuine edge when conditions get difficult. Whether that is down to the types of horses she trains, how she prepares them, or simply a knack for picking the right races in the right weather, the numbers are too consistent to ignore.
Her most regular jockey partnership is with Silvestre De Sousa, who has ridden for her 35 times and come home in front on 3 of those — just under 1 in 12. That is slightly below her yard average, which suggests De Sousa often takes the trickier rides rather than the bankers. Still, 35 rides together in a relatively short training career points to a working relationship built on trust. For a trainer who has already collected seven of racing's biggest prizes in just four seasons, that trust looks well placed.
