Tabitha Worsley(3)

This season she has ridden 7 winners from 174 races — that's roughly 1 in every 25, a 4% win rate. On paper that sounds modest, but context matters. Racing is brutally competitive, and most of those 174 rides will have come on horses with limited realistic chances. What's more encouraging is the direction of travel: last year she was winning at 3%, and she's nudged that up to 4% this season. Small margins, but in this sport, small margins are how careers are built.

Her most regular partnership is with trainer Georgie Howell, for whom she has ridden 34 times and produced 1 winner — around 3%. That's a lower conversion rate than her overall figures, which suggests Howell's horses may not always arrive at the races as the most fancied, but 34 rides from one yard is a meaningful relationship, and loyalty and consistency between a jockey and a trainer tend to pay off over time. It's the kind of stable connection that gives a young rider a reliable stream of racecourse experience, which at this stage of a career is arguably as valuable as winners.

Forty career winners in four years, a gradually improving record, and a trainer who keeps putting her up — Worsley is doing the quiet, unglamorous work that eventually turns promising apprentices into established jockeys. The weight allowance won't last forever, and how she performs once it disappears will be the real test. For now, the arrow is pointing in the right direction.
