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 (2.6% over 38 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, 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.

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 20 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 Maggs's strike rate?
William Maggs has won 63 of 587 rides since 2022, a strike rate of 10.7% (as at 20 October 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 — 7 rides, which is not a sample we will draw a conclusion from.
What is William Maggs's Fair A/E?
1.03, from 586 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 20 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
