KTB Yard Profile

Sends out around 250 runners a season, almost all over hurdles and fences, winning with 14% of them — level with the margin-free market read across five seasons (Fair A/E 1.00). Debutants are a strength: 16% on first career starts (96 runs).

The read

The record is strongest at Hereford (28.3%, n=53) and Carlisle (25%, n=36) — all clear of the yard's 14.1% baseline. It is weakest at Cheltenham (3.7% over 54 runners) — the widest gap in the record. In Group and Graded company the record reads poorly at 1.8% (n=56, Fair A/E 0.21). Runners with a claiming rider up are the standout value angle: 15.4% strikes only just above baseline, but Fair A/E 1.19 and +20.71 to a £1 stake over 136 runners — a record the market has persistently underpriced. Jonjo O'Neill Jr rides 65% of the entries and matches the yard's average almost exactly (15.6%, A/E 0.98) — the market has that partnership priced right. The record reads poorly in Class 1 — 2.4% over 85 runners, 11.7pts below the baseline. 43 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the John Smith's Grand National Chase at Aintree (Apr 2010, £521,053). The stable star of the record: Albertas Run (IRE) — 15 wins from 36 runs for the yard. Seasonally, the yard fires Dec–Jan.

Each tile is the record in that situation vs the 14.1% 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.

Where they came from · where they went next

Of the 60 horses listed, 19 arrived from another yard in our archive, most often from Joseph Patrick O'Brien (3) and Ms Margaret Mullins (2); 41 had their first archived run for this yard.

42 have since run for another yard, most often for Jonjo & A J O'Neill (37); 18 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 Jonjo O'Neill's strike rate?
Jonjo O'Neill has won 176 of 1,246 runners since 2022, a strike rate of 14.1% (as at 15 October 2026). Figures are computed from our own results archive.
Which course does Jonjo O'Neill do best at?
Hereford by strike rate: 15 wins from 53 runners (28.3%) 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 Jonjo O'Neill?
Jonjo O'Neill Jr, with 815 runners since 2022 — 65% of the total. That pairing has won 127 (15.6%).
What is Jonjo O'Neill's Fair A/E?
1.00, from 1,242 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 15 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
