KTB Rider Profile

Rides around 40 times a season, almost all over hurdles and fences, winning on 16% of them — beating the margin-free market read across five seasons (Fair A/E 1.14). In Group and Graded company the record reads 18% (95 runs). Rides mostly for A Chaille-Chaille — 41% of rides in the window.

The read

It is weakest at Compiegne (FR) (10% over 30 rides) — the widest gap in the record. Rides in big fields of 14 or more have been a poor signal at 4.5% (n=44, Fair A/E 0.55). A Chaille-Chaille supplies 41% of the rides and beats the rider's average (24.4% vs 15.7%, A/E 1.25) — the partnership beats the margin-free market read. The rider also reads well off a 61-180-day break (22.2%, n=45). 42 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Prix la Haye Jousselin at Auteuil (FR) (Nov 2025, £200,826). The standout partner of the record: Hawai Du Berlais (FR) — 6 wins from 10 rides together.

Each tile is the record in that situation vs the 15.7% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

Showing the 60 most-raced of the 88 horses ridden in this window — each ran at least 1 time. Horses with fewer runs aren't listed; search finds any horse since 2005. Runs, wins and places only: a strike rate or a return on a handful of runs is noise, so none is quoted per horse — each horse's full record is on its own page.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 12 Nov 2026 — what they have done, not a forecast. A going or a distance is named only where at least 100 progeny runs sit 3 or more points from the sire's own win rate. Distance bands cover Flat and jumps together.

Quick answers

What is Pierre Dubourg's strike rate?
Pierre Dubourg has won 30 of 191 rides since 2022, a strike rate of 15.7% (as at 12 November 2026). Figures are computed from our own results archive.
Which course does Pierre Dubourg do best at?
Auteuil (FR) by strike rate: 27 wins from 161 rides (16.8%) since 2022. Read from the 15 courses with the most rides on the same basis, and only those with at least 30 — a small sample cannot top the list, and a rarely-visited course is not in the comparison.
Which yard does Pierre Dubourg ride most for?
A Chaille-Chaille, with 78 rides since 2022 — 41% of the total. That pairing has won 19 (24.4%).
What is Pierre Dubourg's Fair A/E?
1.14, from 191 rides with a computed fair probability since 2022. Fair A/E compares actual wins with a margin-stripped market expectation, so 1.00 is par: above it the wins came at bigger prices than the margin-free market implied, below it they did not.
Fair A/E compares wins with a margin-stripped market expectation. Favourite-heavy samples — top yards, leading riders — naturally read a few points warm, so 1.05 means "beat the margin-free market read", not "the market underrates this by 5%". Three sample sizes are reported and never blended: runs (n), the ROI basis (n at SP), and the fair-A/E basis (n with a computed fair probability).

Strike rate is wins over all runs (n). ROI is £1 level stakes at SP over runs with a parseable price (n at SP). Fair A/E is wins over margin-stripped market expectation, over runs with a computed fair probability (n fair). The three Ns can legitimately differ and are always shown. Figures as at 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
