Andrew Mullen
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%".
Rides around 530 times a season, almost all on the flat, winning on 8% of them — level with the margin-free market read across five seasons (Fair A/E 1.00). Riding last-time-out winners the record reads 19% (233 rides). Rides mostly for Iain Jardine — 45% of rides in the window. The rider is quiet just now — 0 winners in the last fortnight, below their own baseline.
The record is strongest at Hamilton (15.7%, n=280), clear of the rider's 8.4% baseline. It is weakest at York (0% over 87 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 18.5% (n=233, Fair A/E 1.25), but rides in big fields of 14 or more have been a poor signal at 1.3% (n=238, Fair A/E 0.30). The market has consistently overbet horses returning fresh after 61+ days: 3.9% strike, Fair A/E 0.78 and −162.00 to a £1 stake over 305 rides — those runners underperform what the price implies. Right now the rider is in a quiet spell: 0 from 15 rides in the last 14 days (0%, 8.4pts below the 8.4% baseline). Iain Jardine supplies 45% of the rides and matches the rider's average almost exactly (9.3%, A/E 1.01) — the market has that partnership priced right. The rider also reads well off a 0-7-day break (16.9%, n=160). 4 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Weatherbys Racing Bank 300,000 2-Y-O Stakes at Doncaster (Sep 2018, £147,540). The standout partner of the record: The Gay Blade (GB) — 8 wins from 44 rides together. Seasonally, the rider fires Nov–Dec.
Riding patterns
the angles behind the record · vs 8.4% baselineEach tile is the record in that situation vs the 8.4% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

KTB’s figures
the forward record · since 5 Oct 2026KTB’s figures on this rider’s mounts since 6 Oct 2026: the KTB Selection in 1 run (won 0) · top-rated on KTB Rating in 3 runs (won 0) · fastest on KTB Speed in 4 runs (won 0) · to 27 Oct 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 Andrew Mullen's strike rate?

- Which course does Andrew Mullen do best at?
- Hamilton by strike rate: 44 wins from 280 rides (15.7%) since 2022. Read from the 15 courses with the most rides 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.
- Which yard does Andrew Mullen ride most for?
- Iain Jardine, with 1,200 rides since 2022 — 45% of the total. That pairing has won 112 (9.3%).
- Is Andrew Mullen in form?

- What is Andrew Mullen's Fair A/E?
- 1.00, from 2,646 rides 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.
