KTB Yard Profile

Sends out around 120 runners a season, across both codes, winning with 5% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.87). Horses in first-time headgear strike at 8% (64 runs, true-first definition).

The read

The record is strongest at Saint-Cloud (12.5%, n=48) and Longchamp (FR) (13.3%, n=30) — all clear of the yard's 5.2% baseline. The market has consistently overbet runners with a claiming rider up: 5.2% strike, Fair A/E 0.85 and −135.85 to a £1 stake over 251 runners — those runners underperform what the price implies. N Ferreira rides 34% of the entries and matches the yard's average almost exactly (3.8%, A/E 0.58). The yard also reads well over 1m2f – 1m4f (10.6%, n=104) and on Good to Soft going (10.8%, n=37). 4 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix Jean Victor at Auteuil (FR) (Jun 2023, £43,805). The stable star of the record: Anctot (FR) — 6 wins from 41 runs for the yard. Seasonally, the yard fires Mar–Apr.

Each tile is the record in that situation vs the 5.2% 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 95 horses sent out in this window — each ran at least 2 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, 15 arrived from another yard in our archive, most often from E Lecoiffier (2) and M Seror (2); 45 had their first archived run for this yard.

16 have since run for another yard, most often for D Cottin (3); 44 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.

Quick answers

What is S Dehez's strike rate?
S Dehez has won 32 of 614 runners since 2022, a strike rate of 5.2% (as at 21 October 2026). Figures are computed from our own results archive.
Which course does S Dehez do best at?
Longchamp (FR) by strike rate: 4 wins from 30 runners (13.3%) since 2022. 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 S Dehez?
N Ferreira, with 210 runners since 2022 — 34% of the total. That pairing has won 8 (3.8%).
Is S Dehez in form?
Too few runners in the last 14 days to read — 5 runners, which is not a sample we will draw a conclusion from.
What is S Dehez's Fair A/E?
0.87, from 613 runners 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 21 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
