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%".
KTB Yard Profile
Sent out around 30 runners a season, winning with 13% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.83). Debutants are a strength: 20% on first career starts (55 runs).

The read
Debutants strike at 20% (n=55, Fair A/E 0.00), but in Group and Graded company the record reads poorly at 8.9% (n=56, Fair A/E 0.81). Christophe Herpin rode 53% of the entries and sits below the yard's average (9.7% vs 13.4%, A/E 0.66). The yard also read well off a 31-60-day break (24.2%, n=33) and in Flat races (21.7%, n=60). The record read poorly off a 15-30-day break — 6.8% over 59 runners, 6.6pts below the baseline. The market has consistently overbet the yard in Hurdle races: Fair A/E 0.63 across 72 runners (8.3% strike, −26.80 to a £1 stake) — runners there underperformed what the price implied. 5 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Grande Course de Haies de Primtemps at Auteuil (FR) (May 2008, £51,287). The stable star of the record was Nono Des Ongrais (FR) — 5 wins from 21 runs for the yard.

Each tile is the record in that situation vs the 13.4% 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.

Rows below n=30 are shown faded — a small sample is a fact, not a trend. Every figure carries its N.
Chases and hurdles only — bumpers have no obstacles, so completion is not a question there. F fell · UR unseated rider · PU pulled up · BD brought down · Oth covers refusals, slip-ups, run-outs and the rare disqualification. Non-runners are excluded throughout. Rows under n=30 are shown faded. A descriptive record, not a tip.
Showing the 60 most-raced of the 63 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, 1 arrived from another yard in our archive; 59 had their first archived run for this yard.
14 have since run for another yard, most often for P Chemin & C Herpin (10) and Nicky Henderson (2); 46 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.

Top line: the yard's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 2 Nov 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.
The record
latest 50 of 284 · newest first
The latest 50 of 284 archived runners, newest first. The full record runs from 27 March 2005 to 11 April 2017.
Drawn from the whole archive (2005 onwards), so it can include runs outside the window the header statistics cover. Non-runners are not listed. A finish shown in letters is a non-completion (F fell · UR unseated · PU pulled up · BD brought down).
Quick answers
What is P Chemin's strike rate?
P Chemin has won 34 of 253 runners since 2008, a strike rate of 13.4% (as at 2 November 2026). Figures are computed from our own results archive.
Which course does P Chemin do best at?
Auteuil (FR) by strike rate: 13 wins from 131 runners (9.9%) 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.
Who rides most for P Chemin?
Christophe Herpin, with 134 runners since 2008 — 53% of the total. That pairing has won 13 (9.7%).
What is P Chemin's Fair A/E?
0.83, from 185 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.
