Her most productive relationship is with the Nigel and Willy Twiston-Davies yard, one of the better-known training operations in jump racing. Together they have produced 2 wins from 11 races — that's winning almost 1 in every 5 rides, which is a genuinely strong return and suggests a working partnership that has real chemistry. When a trainer keeps putting the same jockey up, it usually means there's trust on both sides.
Perhaps the most intriguing detail in her record is how she performs when the ground gets soft and slightly heavy after rain. In those conditions, she has won 2 races from just 5 rides — 40%, or 2 in every 5. That is a remarkable number. It could mean she rides particularly well in testing conditions, or that the horses she's placed on in the wet happen to suit that ground. Either way, if you ever see her name on a racecard after a rainy week, that's worth noticing.
Still only four years in, Jackson-Fennell is at the stage of her career where partnerships are formed and reputations start to take shape. The Twiston-Davies connection gives her a strong platform, and a record that delivers at 1 in 8 across all conditions — climbing to nearly 1 in 2 on soft ground — suggests there's a jockey here who
