KTB Rider Profile

The read

Rides on last-time-out winners have been a positive signal at 17.4% (n=155, Fair A/E 1.02), but horses returning fresh after 61+ days have been a poor signal at 2.5% (n=284, Fair A/E 0.56). The market has consistently overbet first rides on a horse: 3.5% strike, Fair A/E 0.65 and −410.50 to a £1 stake over 594 rides — those runners underperform what the price implies. Tony Carroll supplies 30% of the rides and edges the rider's average (10.1% vs 7.3%, A/E 1.08) — the partnership beats the margin-free market read. The rider also reads well on Heavy going (19.4%, n=31). The record reads poorly off a break of 180+ days — 1.1% over 91 rides, 6.2pts below the baseline. 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.

Each tile is the record in that situation vs the 7.3% baseline — descriptive splits with the sample always shown, not tips. 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.

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.

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.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 23 Oct 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 William Carson's strike rate?
William Carson has won 148 of 2,032 rides since 2022, a strike rate of 7.3% (as at 23 October 2026). Figures are computed from our own results archive.
Which course does William Carson do best at?
Epsom by strike rate: 4 wins from 31 rides (12.9%) 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 William Carson ride most for?
Tony Carroll, with 603 rides since 2022 — 30% of the total. That pairing has won 61 (10.1%).
Is William Carson in form?
Too few rides in the last 14 days to read — 9 rides, which is not a sample we will draw a conclusion from.
What is William Carson's Fair A/E?
0.90, from 2,017 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.
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 23 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
