KTB Yard Profile

Sent out around 40 runners a season, almost all on the flat, winning with 13% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.91). Debutants are a strength: 15% on first career starts (178 runs).

KTB at a glance Fired May–Jun 37% when favourite Olivier Peslier: 13.6% from 88 Sent off the favourite in 8% of races
The read

It is weakest at Saint-Cloud (FR) (8.1% over 62 runners) — the widest gap in the record. Olivier Peslier rode 16% of the entries and matches the yard's average almost exactly (13.6%, A/E 0.89). The yard also read well over 1m2f – 1m4f (16.6%, n=193). The record read poorly on Heavy going — 8.6% over 35 runners, 4.4pts below the baseline. The market has consistently overbet the yard off a 31-60-day break: Fair A/E 0.63 across 89 runners (9% strike, −34.40 to a £1 stake) — runners there underperformed what the price implied. 11 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix Fille de l'Air at Toulouse (FR) (Nov 2009, £38,835). Seasonally, the yard fired May–Jun.

Each tile is the record in that situation vs the 13% baseline — descriptive splits with the sample always shown, not tips. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races.

Showing the 60 most-raced of the 198 horses sent out in this window — each ran at least 3 times. 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.
Where they came from · where they went next

Of the 60 horses listed, 7 arrived from another yard in our archive, most often from C Ferland (2); 53 had their first archived run for this yard.

35 have since run for another yard, most often for W P Mullins (3) and N Bertran De Balanda (2); 25 have no later run for another yard in our archive.

Read from each listed horse's whole archived career (2005 onwards), not only this window, and counted over the horses listed above, not the whole string. “First archived run” means our archive holds nothing earlier, not that the horse was unraced. A horse with no later run elsewhere may still be here, be off the track, or have run somewhere our archive does not cover — none of that is asserted.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 22 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 Y Durepaire's strike rate?
Y Durepaire has won 71 of 547 runners since 2008, a strike rate of 13% (as at 22 October 2026). Figures are computed from our own results archive.
Which course does Y Durepaire do best at?
Longchamp (FR) by strike rate: 8 wins from 58 runners (13.8%) since 2008. Read from the 15 courses with the most runners 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.
Who rides most for Y Durepaire?
Olivier Peslier, with 88 runners since 2008 — 16% of the total. That pairing has won 12 (13.6%).
What is Y Durepaire's Fair A/E?
0.91, from 454 runners with a computed fair probability since 2008. 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 22 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
