William Carson
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 440 times a season, almost all on the flat, winning on 8% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.95). Riding last-time-out winners the record reads 17% (707 rides).
Rides on last-time-out winners have been a positive signal at 17.3% (n=707, Fair A/E 1.07), but horses returning fresh after 61+ days have been a poor signal at 4.7% (n=1,075, Fair A/E 0.78). The market has consistently overbet first rides on a horse: 5.1% strike, Fair A/E 0.80 and −1,367.70 to a £1 stake over 2,944 rides — those runners underperform what the price implies. Tony Carroll supplies 10% of the rides and matches the rider's average almost exactly (9.6%, A/E 1.05) — the partnership beats the margin-free market read. The rider also reads well off a 0-7-day break (13.7%, n=651). 6 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the John Smith's Ayr Gold Cup Heritage Handicap at Ayr (Sep 2008, £93,465). The standout partner of the record: The Craftymaster (GB) — 9 wins from 28 rides together. Seasonally, the rider fires Dec–Mar.
Riding patterns
the angles behind the record · vs 8.1% baselineEach tile is the record in that situation vs the 8.1% 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 5 Oct 2026: the KTB Selection in 3 runs (won 0, 1 did not run) · top-rated on KTB Rating in 2 runs (won 0) · fastest on KTB Speed in 8 runs (won 0) · to 7 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 William Carson's strike rate?
- William Carson has won 683 of 8,439 rides since 2008, a strike rate of 8.1% (as at 10 November 2026). Figures are computed from our own results archive.
- Which course does William Carson do best at?
- Leicester by strike rate: 19 wins from 165 rides (11.5%) since 2008. 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 William Carson ride most for?
- Tony Carroll, with 848 rides since 2008 — 10% of the total. That pairing has won 81 (9.6%).
- Is William Carson in form?

- What is William Carson's Fair A/E?
- 0.95, from 8,391 rides 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.
