Sir Mark Prescott Bt
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%".
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 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.
Yard patterns
the angles behind the record · vs 18.3% baselineEach 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.

KTB’s figures
the forward record · since 5 Oct 2026KTB’s figures on this yard’s runners since 6 Oct 2026: the KTB Selection in 6 runs (won 2, 1 did not run) · top-rated on KTB Rating in 2 runs (won 0) · fastest on KTB Speed in 2 runs (won 0) · to 2 Nov 2026.
Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.
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.
