KTB Rider Profile

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).

The read

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.

Each 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.

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 10 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.

KTB’s figures

the forward record · since 5 Oct 2026

KTB’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?
In the last 14 days: 18 rides, 1 winner, a strike rate of 5.6%. That is in line with the baseline of 8.1% since 2008.
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.
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 10 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
