Each bar shows winners divided by runners. Wins/runs are visible on every row. Hover or focus a bar for its figures. A missing record is shown as “No recorded runs”, not a zero win rate. Selected jockeys stay visible even when they fall below the minimum-runner filter; their sample is flagged.

All UK & Ireland Jockeys means jockeys with recorded starters at GB/Irish racecourses in the selected research window; it does not classify a jockey’s nationality. Search includes names across the stored 10-year window. The simple chart lists every recorded jockey from the 10-year UK/Ireland catalogue, including those with no runs in the chosen condition. Detailed comparison shows 50 rows at a time; Show more reveals the rest.

Only completed races with a recorded winner before today are included. Imported history through 13 October 2026 is combined with current stored results from 14 October onwards. Latest horse/race records are used for current results. Dead-heat winners count as winning runners. Non-runners are excluded.

Class/grade uses the recorded Group, Grade or Listed designation where available, otherwise the recorded race class. Ambiguous G1/G2/G3 codes remain labelled “Group/Grade”. Going names retain supplied wording, including all-weather conditions. No missing grade, age or going is inferred. Comparisons reflect different horses, races and samples; they do not isolate jockey ability.
