KTB Rider Profile

Rides around 30 times a season, almost all over hurdles and fences, winning on 7% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.86). In big fields of 14 or more the record reads 9% (43 rides). Rides mostly for Gabriel Leenders — 67% of rides in the window.

The read

The market has consistently overbet first rides on a horse: 5.8% strike, Fair A/E 0.70 and −42.25 to a £1 stake over 103 rides — those runners underperform what the price implies. Gabriel Leenders supplies 67% of the rides and matches the rider's average almost exactly (7.8%, A/E 0.94). The record reads poorly off a 61-180-day break — 3.1% over 32 rides, 4.1pts below the baseline. The market has consistently overbet the rider on Heavy going: Fair A/E 0.67 across 75 rides (5.3% strike, −27.80 to a £1 stake) — runners there underperform what the price implies. 2 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Prix Saint-Sauveur at Auteuil (FR) (May 2026, £38,348).

Each tile is the record in that situation vs the 7.2% 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.

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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 13 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 Theo Dumouch's strike rate?
Theo Dumouch has won 11 of 153 rides since 2022, a strike rate of 7.2% (as at 13 November 2026). Figures are computed from our own results archive.
Which course does Theo Dumouch do best at?
Auteuil (FR) by strike rate: 5 wins from 78 rides (6.4%) 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.
Which yard does Theo Dumouch ride most for?
Gabriel Leenders, with 102 rides since 2022 — 67% of the total. That pairing has won 8 (7.8%).
What is Theo Dumouch's Fair A/E?
0.86, from 151 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 13 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
