KTB Yard Profile

Sent out around 160 runners a season, almost all on the flat, winning with 9% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.91).

The read

The record is strongest at Yarmouth (14.3%, n=70), clear of the yard's 8.5% baseline. It is weakest at Newmarket (0% over 31 runners) — the widest gap in the record. New recruits from other stables on their first run struggle at 0% (n=30, Fair A/E 0.00). The market has consistently overbet horses returning fresh after 61+ days: 6.2% strike, Fair A/E 0.84 and −52.62 to a £1 stake over 241 runners — those runners underperformed what the price implied. Stevie Donohoe rode 21% of the entries and matches the yard's average almost exactly (8.9%, A/E 0.88). The yard also read well off a 0-7-day break (27.5%, n=51). The stable star of the record was Bold Adventure (GB) — 12 wins from 88 runs for the yard. Seasonally, the yard fired Nov–Jan.

Each tile is the record in that situation vs the 8.5% 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.

The 60 most-raced of 127 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 60 horses listed, 21 arrived from another yard in our archive, most often from F Head (2); 39 had their first archived run for this yard.

17 have since run for another yard, most often for Henry Spiller (3); 43 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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 15 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 Willie Musson's strike rate?
Willie Musson has won 120 of 1,412 runners since 2008, a strike rate of 8.5% (as at 15 October 2026). Figures are computed from our own results archive.
Which course does Willie Musson do best at?
Yarmouth by strike rate: 10 wins from 70 runners (14.3%) since 2008. 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 Willie Musson?
Stevie Donohoe, with 303 runners since 2008 — 21% of the total. That pairing has won 27 (8.9%).
What is Willie Musson's Fair A/E?
0.91, from 1,402 runners with a computed fair probability since 2008. 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).
