KTB Yard Profile

Sends out around 170 runners a season, almost all on the flat, winning with 9% of them — beating the margin-free market read across five seasons (Fair A/E 1.08).

The read

The record is strongest at Dundalk (AW) (14.9%, n=276), clear of the yard's 9% baseline. In Group and Graded company the record reads poorly at 1.9% (n=53, Fair A/E 0.27). Luke McAteer rides 52% of the entries and edges the yard's average (12.2% vs 9%, A/E 1.19) — the partnership beats the margin-free market read. The yard also reads well on Standard (AW) going (15.1%, n=285). The record reads poorly in Class 1 — 1.9% over 53 runners, 7.1pts below the baseline. 4 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Royal Hunt Cup at Ascot (Jun 2018, £108,938). The stable star of the record: Jered Maddox (GB) — 13 wins from 89 runs for the yard.

Each tile is the record in that situation vs the 9% 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 106 horses sent out in this window — each ran at least 4 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, 6 arrived from another yard in our archive, most often from M Halford & T Collins (3); 54 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.

Quick answers

What is David Marnane's strike rate?
David Marnane has won 78 of 864 runners since 2022, a strike rate of 9% (as at 21 October 2026). Figures are computed from our own results archive.
Which course does David Marnane do best at?
Dundalk (AW) by strike rate: 41 wins from 276 runners (14.9%) 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 David Marnane?
Luke McAteer, with 452 runners since 2022 — 52% of the total. That pairing has won 55 (12.2%).
Is David Marnane in form?
Too few runners in the last 14 days to read — 14 runners, which is not a sample we will draw a conclusion from.
What is David Marnane's Fair A/E?
1.08, from 863 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 21 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
