KTB Rider Profile

Rides around 20 times a season, almost all over hurdles and fences, winning on 13% of them — beating the margin-free market read across five seasons (Fair A/E 1.24).

Deterministic profile computed from 107 archived runs (last 5 seasons) · updated 20 Oct 2026
The read

It is weakest at Auteuil (FR) (4% over 50 rides) — the largest sample in the record, and the widest gap. Horses returning fresh after 61+ days have been a poor signal at 9.4% (n=32, Fair A/E 0.88). The rider also reads well on Heavy going (20.9%, n=43). The record reads poorly on Soft going — 8.8% over 57 rides, 4.3pts below the baseline. One Group or Graded win sits in the archive record — the biggest prize the rider has landed: the 139eme Grand Prix de Pau - Biraben Foie Gras - Prix Andre Labarrere at Pau (FR) (Jan 2026, £55,957).

Each tile is the record in that situation vs the 13.1% baseline — descriptive splits with the sample always shown, not tips. 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.

Descriptive splits ranked by divergence × sample — insight, not instruction. Every angle carries its N; nothing under 30 runs qualifies. Rows within 2pts of the baseline appear only when the market-relative read (Fair A/E) diverges, and show it.

Showing the 60 most-raced of the 70 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 20 Oct 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 Quentin Defontaine's strike rate?
Quentin Defontaine has won 14 of 107 rides since 2022, a strike rate of 13.1% (as at 20 October 2026). Figures are computed from our own results archive.
Which course does Quentin Defontaine do best at?
Auteuil (FR) by strike rate: 2 wins from 50 rides (4%) 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.
Is Quentin Defontaine in form?
Too few rides in the last 14 days to read — 2 rides, which is not a sample we will draw a conclusion from.
What is Quentin Defontaine's Fair A/E?
1.24, from 104 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.
