KTB Yard Profile

Sends out around 80 runners a season, across both codes, winning with 12% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.95).

The read

The record is strongest at Leicester (26.5%, n=49), clear of the yard's 11.7% baseline. Horses returning fresh after 61+ days have been a poor signal at 7.9% (n=89, Fair A/E 0.74). Paul O'Brien rides 30% of the entries and matches the yard's average almost exactly (10.8%, A/E 0.81). The yard also reads well over 2m5f – 3m (22.9%, n=35) and in Chase races (19.6%, n=92). The record reads poorly off a break of 180+ days — 2.1% over 48 runners, 9.6pts below the baseline. The market has consistently overbet the yard in Hurdle races: Fair A/E 0.41 across 106 runners (3.8% strike, −81.62 to a £1 stake) — runners there underperform what the price implies. 5 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Stan James 1000 Guineas Stakes at Newmarket (May 2006, £187,374). The stable star of the record: Samarinda (USA) — 9 wins from 54 runs for the yard.

Each tile is the record in that situation vs the 11.7% 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 43 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 43 horses listed, 5 arrived from another yard in our archive, most often from Micky Fenton (3); 38 had their first archived run for this yard.

10 have since run for another yard, most often for Olly Williams (3) and Hayley Burton (2); 33 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.

Top line: the yard's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 19 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 Pam Sly's strike rate?
Pam Sly has won 46 of 394 runners since 2022, a strike rate of 11.7% (as at 19 October 2026). Figures are computed from our own results archive.
Which course does Pam Sly do best at?
Leicester by strike rate: 13 wins from 49 runners (26.5%) 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 Pam Sly?
Paul O'Brien, with 120 runners since 2022 — 30% of the total. That pairing has won 13 (10.8%).
Is Pam Sly 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 Pam Sly's Fair A/E?
0.95, from 393 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).
