KTB Yard Profile

Sends out around 10 runners a season, almost all on the flat, winning with 14% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.50).

Deterministic profile computed from 106 archived runs (lifetime window) · updated 1 Nov 2026
The read

The record is strongest at Chantilly (FR) (20%, n=30), clear of the yard's 14.2% baseline. It is weakest at Deauville (FR) (5.1% over 39 runners) — the largest sample in the record, and the widest gap. Horses returning fresh after 61+ days have been a poor signal at 10.9% (n=46, Fair A/E 1.67). The market has also underrated the yard on Standard (AW) going: Fair A/E 1.64 across 65 runners (12.3% strike, +20.30 to a £1 stake). 5 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix Max Sicard at Toulouse (FR) (Dec 2017, £25,641). The stable star of the record: Holdthasigreen (FR) — 6 wins from 16 runs for the yard.

Each tile is the record in that situation vs the 14.2% baseline — descriptive splits with the sample always shown, for you to weigh. 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. The same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.

All 26 horses sent out in this window. 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 26 horses listed, 10 arrived from another yard in our archive, most often from G Henrot (3); 16 had their first archived run for this yard.

8 have since run for another yard, most often for B Audouin (6); 18 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.

In our archive from its very first year (2005), so this career almost certainly began earlier than our record does. The figures above count 2005 onwards only — what the archive holds, not a full-career total. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.

Top line: the yard'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 1 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 C Le Lay's strike rate?
C Le Lay has won 15 of 106 runners since 2008, a strike rate of 14.2% (as at 1 November 2026). Figures are computed from our own results archive.
Which course does C Le Lay do best at?
Chantilly (FR) by strike rate: 6 wins from 30 runners (20%) 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.
What is C Le Lay's Fair A/E?
1.50, from 101 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.
