KTB Yard Profile

Sends out around 20 runners a season, almost all over hurdles and fences, winning with 3% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.58).

KTB at a glance Derek Fox: 5.9% from 51
The read

Derek Fox rides 41% of the entries and edges the yard's average (5.9% vs 3.2%, A/E 1.10) — the partnership beats the margin-free market read. The yard also reads well on Good to Soft going (7.5%, n=40). The record reads poorly in Hurdle races — 0% over 53 runners, 3.2pts below the baseline. The market has consistently overbet the yard in Chase races: Fair A/E 0.78 across 68 runners (5.9% strike, −24.62 to a £1 stake) — runners there underperform what the price implies. The stable star of the record: Sword Of Fate (IRE) — 8 wins from 82 runs for the yard.

Each tile is the record in that situation vs the 3.2% 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.

All 11 horses sent out in this window. 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 11 horses listed, 8 arrived from another yard in our archive, most often from Fergal O'Brien (3); 3 had their first archived run for this yard.

None of them has a 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.

Quick answers

What is Leonard Kerr's strike rate?
Leonard Kerr has won 4 of 124 runners since 2022, a strike rate of 3.2% (as at 19 October 2026). Figures are computed from our own results archive.
Which course does Leonard Kerr do best at?
Perth by strike rate: 2 wins from 35 runners (5.7%) 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 Leonard Kerr?
Derek Fox, with 51 runners since 2022 — 41% of the total. That pairing has won 3 (5.9%).
Is Leonard Kerr in form?
Too few runners in the last 14 days to read — 1 runner, which is not a sample we will draw a conclusion from.
What is Leonard Kerr's Fair A/E?
0.58, from 124 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 19 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
