KTB Yard Profile

Sends out around 30 runners a season, almost all on the flat, winning with 5% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.76). New recruits from other yards win at 7% first time out (82 runs). The yard is quiet just now — 0 winners in the last fortnight, below its own baseline.

KTB at a glance Fires Dec–Jan Thomas Trullier: 4.6% from 65 New recruits: 7.3% Claiming riders: 7.1%
The read

The record is strongest at Longchamp (FR) (10%, n=80), clear of the yard's 5.1% baseline. The market has consistently overbet horses returning fresh after 61+ days: 3.9% strike, Fair A/E 0.60 and −129.30 to a £1 stake over 206 runners — those runners underperform what the price implies. Right now the yard is in a quiet spell: 0 from 15 runners in the last 14 days (0%, 5.1pts below the 5.1% baseline). Thomas Trullier rides 11% of the entries and matches the yard's average almost exactly (4.6%, A/E 0.88). The record reads poorly over 6f – 7f — 0% over 63 runners, 5.1pts below the baseline. The market has consistently overbet the yard off a 8-14-day break: Fair A/E 0.21 across 67 runners (1.5% strike, −63.40 to a £1 stake) — runners there underperform what the price implies. Seasonally, the yard fires Dec–Jan.

Each tile is the record in that situation vs the 5.1% 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.

Showing the 60 most-raced of the 137 horses sent out in this window — each ran at least 4 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, 37 arrived from another yard in our archive, most often from Y Barberot (4) and C Ferland (3); 23 had their first archived run for this yard.

15 have since run for another yard, most often for Mme E Cury (2); 45 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 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 Yoann Bonnefoy's strike rate?
Yoann Bonnefoy has won 30 of 591 runners since 2008, a strike rate of 5.1% (as at 12 November 2026). Figures are computed from our own results archive.
Which course does Yoann Bonnefoy do best at?
Longchamp (FR) by strike rate: 8 wins from 80 runners (10%) 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 Yoann Bonnefoy?
Thomas Trullier, with 65 runners since 2008 — 11% of the total. That pairing has won 3 (4.6%).
Is Yoann Bonnefoy in form?
In the last 14 days: 15 runners, 0 winners, a strike rate of 0%. That is below the baseline of 5.1% since 2008.
What is Yoann Bonnefoy's Fair A/E?
0.76, from 589 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 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
