KTB Yard Profile

Sends out around 720 runners a season, almost all on the flat, winning with 22% of them — beating the margin-free market read across five seasons (Fair A/E 1.05). The edge shows sharpest with horses returning fresh: 26% off breaks of two months or more (614 runs). The yard is quiet just now — 8 winners in the last fortnight, below its own baseline.

The read

The record is strongest at Pontefract (42.5%, n=40), Ripon (40.8%, n=49) and Ayr (36.7%, n=30) — all clear of the yard's 21.6% baseline. It is weakest at Newmarket (13.1% over 221 runners) — the widest gap in the record. Horses returning fresh after 61+ days have been a positive signal at 26.2% (n=614, Fair A/E 1.14), but debutants struggle at 13.4% (n=477, Fair A/E 0.96). Right now the yard is in a quiet spell: 8 from 44 runners in the last 14 days (18.2%, 3.4pts below the 21.6% baseline). Tom Marquand rides 41% of the entries and matches the yard's average almost exactly (21.1%, A/E 1.03) — the market has that partnership priced right. The yard also reads well off a 61-180-day break (30.5%, n=325). 334 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Royal Bahrain Irish Champion Stakes at Leopardstown (Sep 2024, £712,500). The stable star of the record: Hamish (GB) — 15 wins from 29 runs for the yard.

Each tile is the record in that situation vs the 21.6% 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 600 horses sent out in this window — each ran at least 12 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, 2 arrived from another yard in our archive; 58 had their first archived run for this yard.

12 have since run for another yard; 48 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 24 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 William Haggas's strike rate?
William Haggas has won 774 of 3,578 runners since 2022, a strike rate of 21.6% (as at 24 October 2026). Figures are computed from our own results archive.
Which course does William Haggas do best at?
Newcastle (AW) by strike rate: 46 wins from 159 runners (28.9%) 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 William Haggas?
Tom Marquand, with 1,457 runners since 2022 — 41% of the total. That pairing has won 307 (21.1%).
Is William Haggas in form?
In the last 14 days: 44 runners, 8 winners, a strike rate of 18.2%. That is below the baseline of 21.6% since 2022.
What is William Haggas's Fair A/E?
1.05, from 3,553 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 24 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
