KTB Yard Profile

Sends out around 80 runners a season, almost all over hurdles and fences, winning with 5% of them — beating the margin-free market read across five seasons (Fair A/E 1.05).

Deterministic profile computed from 383 archived runs (last 5 seasons) · updated 22 Oct 2026

The read

Alan O'Sullivan rides 22% of the entries and matches the yard's average almost exactly (4.8%, A/E 0.98) — the market has that partnership priced right. The record reads poorly off a 8-14-day break — 1.7% over 58 runners, 3.5pts below the baseline. 3 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Tim Duggan Memorial Handicap Chase at Limerick (Dec 2007, £29,295). The stable star of the record: A Decent Excuse (IRE) — 6 wins from 63 runs for the yard.

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 5.2% 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 68 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, 11 arrived from another yard in our archive, most often from Tom Lacey (3); 49 had their first archived run for this yard.

13 have since run for another yard, most often for W P Mullins (2); 47 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.

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 Eugene M O'Sullivan's strike rate?
Eugene M O'Sullivan has won 20 of 383 runners since 2022, a strike rate of 5.2% (as at 22 October 2026). Figures are computed from our own results archive.
Which course does Eugene M O'Sullivan do best at?
Listowel by strike rate: 3 wins from 47 runners (6.4%) 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 Eugene M O'Sullivan?
Alan O'Sullivan, with 84 runners since 2022 — 22% of the total. That pairing has won 4 (4.8%).
What is Eugene M O'Sullivan's Fair A/E?
1.05, from 383 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 22 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
