KTB Yard Profile

Sends out around 100 runners a season, almost all over hurdles and fences, winning with 10% of them — beating the margin-free market read across five seasons (Fair A/E 1.12). With a claiming rider up the record reads 17% (118 runs).

The read

The record is strongest at Compiegne (FR) (14.7%, n=109), clear of the yard's 9.6% baseline. Runners with a claiming rider up have been a positive signal at 16.9% (n=118, Fair A/E 1.88), but debutants struggle at 6% (n=133, Fair A/E 0.89). Horses returning fresh after 61+ days are the standout value angle: 10.8% strikes only just above baseline, but Fair A/E 1.29 and +63.30 to a £1 stake over 157 runners — a record the market has persistently underpriced. Raphael Mayeur rides 19% of the entries and matches the yard's average almost exactly (10.1%, A/E 1.35) — the partnership beats the margin-free market read. The yard also reads well off a 61-180-day break (14.3%, n=84). 8 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Grande Course de Haies de Printemps Handicap) at Auteuil (FR) (Apr 2025, £64,711). Seasonally, the yard fires Mar–May.

Each tile is the record in that situation vs the 9.6% 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 179 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, 12 arrived from another yard in our archive, most often from Francois Nicolle (2); 48 had their first archived run for this yard.

6 have since run for another yard; 54 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 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 Erwan Grall's strike rate?
Erwan Grall has won 46 of 480 runners since 2022, a strike rate of 9.6% (as at 20 October 2026). Figures are computed from our own results archive.
Which course does Erwan Grall do best at?
Compiegne (FR) by strike rate: 16 wins from 109 runners (14.7%) 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 Erwan Grall?
Raphael Mayeur, with 89 runners since 2022 — 19% of the total. That pairing has won 9 (10.1%).
Is Erwan Grall in form?
Too few runners in the last 14 days to read — 14 runners, which is not a sample we will draw a conclusion from.
What is Erwan Grall's Fair A/E?
1.12, from 477 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).
