KTB Rider Profile

Rides around 120 times a season, almost all over hurdles and fences, winning on 11% of them — beating the margin-free market read across five seasons (Fair A/E 1.03). Riding last-time-out winners the record reads 18% (60 rides).

The read

The record is strongest at Sedgefield (20.4%, n=49), clear of the rider's 10.7% baseline. It is weakest at Hexham (2.5% over 40 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 18.3% (n=60, Fair A/E 0.95), but rides in big fields of 14 or more have been a poor signal at 5.1% (n=59, Fair A/E 0.83). Donald McCain supplies 25% of the rides and matches the rider's average almost exactly (12.2%, A/E 1.04) — the partnership beats the margin-free market read. The rider also reads well off a 8-14-day break (19%, n=63). The record reads poorly in Class 2 — 0% over 31 rides, 10.7pts below the baseline. The standout partner of the record: Lihyan (IRE) — 5 wins from 22 rides together. Seasonally, the rider fires Feb–Apr.

Each tile is the record in that situation vs the 10.7% 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.

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.

KTB’s figures

the forward record · since 5 Oct 2026

KTB’s figures on this rider’s mounts since 8 Oct 2026: the KTB Selection in 1 run (won 0) · top-rated on KTB Rating in 1 run (won 0) · to 18 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 William Maggs's strike rate?
William Maggs has won 63 of 591 rides since 2022, a strike rate of 10.7% (as at 4 November 2026). Figures are computed from our own results archive.
Which course does William Maggs do best at?
Sedgefield by strike rate: 10 wins from 49 rides (20.4%) 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 Maggs ride most for?
Donald McCain, with 148 rides since 2022 — 25% of the total. That pairing has won 18 (12.2%).
Is William Maggs in form?
Too few rides in the last 14 days to read — 2 rides, which is not a sample we will draw a conclusion from.
What is William Maggs's Fair A/E?
1.03, from 590 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 4 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
