KTB Yard Profile

Sent out around 30 runners a season, almost all on the flat, winning with 7% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.74). New recruits from other yards win at 13% first time out (46 runs).

The read

It is weakest at Longchamp (FR) (3% over 33 runners) — the widest gap in the record. New recruits from other stables on their first run win at 13% (n=46, Fair A/E 0.57). The market has consistently overbet horses returning fresh after 61+ days: 9.8% strike, Fair A/E 0.69 and −55.60 to a £1 stake over 133 runners — those runners underperformed what the price implied. The yard also read well on Good to Soft going (19.4%, n=31) and off a break of 180+ days (11.1%, n=63). The record read poorly off a 31-60-day break — 2.4% over 41 runners, 4.9pts below the baseline. The market has consistently overbet the yard on Standard (AW) going: Fair A/E 0.70 across 61 runners (3.3% strike, −27.80 to a £1 stake) — runners there underperformed what the price implied.

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 7.3% 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.

The 60 most-raced of 63 horses sent out in this window. 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, 44 arrived from another yard in our archive, most often from J Heloury (6) and H-A Pantall (4); 16 had their first archived run for this yard.

24 have since run for another yard, most often for E Caroux (5) and M Cesandri (5); 36 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 15 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 P Chatelain's strike rate?
P Chatelain has won 17 of 234 runners since 2008, a strike rate of 7.3% (as at 15 October 2026). Figures are computed from our own results archive.
Which course does P Chatelain do best at?
Maisons-Laffitte (FR) by strike rate: 4 wins from 39 runners (10.3%) 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.
What is P Chatelain's Fair A/E?
0.74, from 205 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 15 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
