KTB Yard Profile

Sends out around 260 runners a season, almost all on the flat, winning with 18% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.05). The edge shows sharpest with horses returning fresh: 22% off breaks of two months or more (728 runs).

The read

The record is strongest at Bath (32%, n=125), clear of the yard's 18.3% baseline. Horses returning fresh after 61+ days have been a positive signal at 22% (n=728, Fair A/E 1.21), but debutants struggle at 4.9% (n=577, Fair A/E 0.71). Luke Morris rides 52% of the entries and matches the yard's average almost exactly (18.2%, A/E 1.03) — the market has that partnership priced right. The yard also reads well off a 0-7-day break (34.4%, n=482) and on Firm going (39.6%, n=91). The market has also underrated the yard in Class 6: Fair A/E 1.26 across 905 runners (29% strike, +78.70 to a £1 stake). 47 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Qatar Prix de l'Arc de Triomphe at Longchamp (FR) (Oct 2022, £2,400,840). The stable star of the record: Don't Be (GB) — 8 wins from 18 runs for the yard. Seasonally, the yard fires May–Aug.

Each tile is the record in that situation vs the 18.3% baseline — descriptive splits with the sample always shown, for you to weigh. 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 same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.

Showing the 60 most-raced of the 633 horses sent out in this window — each ran at least 14 times. 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, 5 arrived from another yard in our archive; 55 had their first archived run for this yard.

19 have since run for another yard, most often for David O'Meara (2) and Paul Nicholls (2); 41 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 12 Nov 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 Sir Mark Prescott Bt's strike rate?
Sir Mark Prescott Bt has won 920 of 5,017 runners since 2008, a strike rate of 18.3% (as at 12 November 2026). Figures are computed from our own results archive.
Which course does Sir Mark Prescott Bt do best at?
Bath by strike rate: 40 wins from 125 runners (32%) 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 Sir Mark Prescott Bt?
Luke Morris, with 2,616 runners since 2008 — 52% of the total. That pairing has won 477 (18.2%).
Is Sir Mark Prescott Bt in form?
Too few runners in the last 14 days to read — 5 runners, which is not a sample we will draw a conclusion from.
What is Sir Mark Prescott Bt's Fair A/E?
1.05, from 4,978 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 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
