KTB Yard Profile

Sends out around 30 runners a season, almost all on the flat, winning with 8% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.64). Horses in first-time headgear strike at 9% (32 runs, true-first definition).

KTB at a glance Guillaume Guedj-Gay: 9.1% from 55
The read

Guillaume Guedj-Gay rides 41% of the entries and matches the yard's average almost exactly (9.1%, A/E 0.58). The yard also reads well off a 31-60-day break (12.5%, n=32). The market has consistently overbet the yard over 1m2f – 1m4f: Fair A/E 0.77 across 76 runners (9.2% strike, −37.22 to a £1 stake) — runners there underperform what the price implies. 18 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Shadwell Rockfel Stakes at Newmarket (Sep 2016, £56,710).

Written from the figures on this page — every claim carries its sample. Descriptive, not a tip.

Each tile is the record in that situation vs the 7.5% 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 69 horses sent out in this window — each ran at least 1 time. 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, 3 arrived from another yard in our archive; 57 had their first archived run for this yard.

3 have since run for another yard; 57 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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 20 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 X Thomas-Demeaulte's strike rate?
X Thomas-Demeaulte has won 10 of 133 runners since 2022, a strike rate of 7.5% (as at 20 October 2026). Figures are computed from our own results archive.
Who rides most for X Thomas-Demeaulte?
Guillaume Guedj-Gay, with 55 runners since 2022 — 41% of the total. That pairing has won 5 (9.1%).
Is X Thomas-Demeaulte in form?
Too few runners in the last 14 days to read — 9 runners, which is not a sample we will draw a conclusion from.
What is X Thomas-Demeaulte's Fair A/E?
0.64, from 133 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 20 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
