KTB Yard Profile

Sends out around 70 runners a season, almost all on the flat, winning with 9% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.03).

The read

It is weakest at Kempton (AW) (3.7% over 109 runners) — the widest gap in the record. Debutants struggle at 0% (n=51, Fair A/E 0.00). The market has consistently overbet horses returning fresh after 61+ days: 5.4% strike, Fair A/E 0.80 and −93.12 to a £1 stake over 186 runners — those runners underperform what the price implies. Hollie Doyle rides 17% of the entries and edges the yard's average (13.3% vs 9.3%, A/E 1.23) — the partnership beats the margin-free market read. The yard also reads well off a 0-7-day break (16.7%, n=48). The record reads poorly off a break of 180+ days — 1.8% over 55 runners, 7.5pts below the baseline. One Group or Graded win sits in the archive record — the biggest prize the yard has landed: the IRE Incentive Scheme Dick Poole Fillies' Stakes at Salisbury (Sep 2021, £25,520). The stable star of the record: Tigerfish (IRE) — 9 wins from 49 runs for the yard. Seasonally, the yard fires Nov–Jan.

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 9.3% 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.

Showing the 60 most-raced of the 84 horses sent out in this window — each ran at least 5 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, 27 arrived from another yard in our archive, most often from Stuart Williams (3) and Jamie Osborne (2); 33 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.

KTB’s figures

the forward record · since 5 Oct 2026

KTB’s figures on this yard’s runners since 12 Oct 2026: the KTB Selection in 1 run (won 0) · fastest on KTB Speed in 1 run (won 0) · to 23 Oct 2026.

Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.

Quick answers

What is William Stone's strike rate?
William Stone has won 129 of 1,380 runners since 2008, a strike rate of 9.3% (as at 30 October 2026). Figures are computed from our own results archive.
Which course does William Stone do best at?
Brighton by strike rate: 10 wins from 65 runners (15.4%) 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 William Stone?
Hollie Doyle, with 241 runners since 2008 — 17% of the total. That pairing has won 32 (13.3%).
Is William Stone in form?
Too few runners in the last 14 days to read — 5 runners, which is not a sample we will draw a conclusion from.
What is William Stone's Fair A/E?
1.03, from 1,374 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 30 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
