KTB Yard Profile

Sends out around 80 runners a season, almost all over hurdles and fences, winning with 13% of them — beating the margin-free market read across five seasons (Fair A/E 1.12). New recruits from other yards win at 18% first time out (34 runs).

The read

The record is strongest at Compiegne (FR) (20.9%, n=110), clear of the yard's 12.6% baseline. It is weakest at Auteuil (FR) (9.3% over 247 runners) — the largest sample in the record, and the widest gap. New recruits from other stables on their first run win at 17.6% (n=34, Fair A/E 1.95), but in Group and Graded company the record reads poorly at 9.6% (n=115, Fair A/E 0.94). Clement Lefebvre rides 31% of the entries and edges the yard's average (15.2% vs 12.6%, A/E 1.12) — the partnership beats the margin-free market read. The yard also reads well in Chase races (16.1%, n=137). The record reads poorly off a break of 180+ days — 7.3% over 41 runners, 5.3pts below the baseline. 19 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix des Drags at Auteuil (FR) (Jun 2022, £83,193). Seasonally, the yard fires Mar–May.

Each tile is the record in that situation vs the 12.6% 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 134 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, 8 arrived from another yard in our archive, most often from Francois Nicolle (2); 52 had their first archived run for this yard.

5 have since run for another yard; 55 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 D Sourdeau De Beauregard's strike rate?
D Sourdeau De Beauregard has won 53 of 420 runners since 2022, a strike rate of 12.6% (as at 7 November 2026). Figures are computed from our own results archive.
Which course does D Sourdeau De Beauregard do best at?
Compiegne (FR) by strike rate: 23 wins from 110 runners (20.9%) 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 D Sourdeau De Beauregard?
Clement Lefebvre, with 132 runners since 2022 — 31% of the total. That pairing has won 20 (15.2%).
Is D Sourdeau De Beauregard in form?
Too few runners in the last 14 days to read — 10 runners, which is not a sample we will draw a conclusion from.
What is D Sourdeau De Beauregard's Fair A/E?
1.12, from 417 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 7 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
