William Pyle
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 70 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 0.84). Riding last-time-out winners the record reads 20% (118 rides).
The record is strongest at Musselburgh (14.3%, n=77), clear of the rider's 8.1% baseline. Rides on last-time-out winners have been a positive signal at 20.3% (n=118, Fair A/E 1.19), but horses returning fresh after 61+ days have been a poor signal at 2% (n=147, Fair A/E 0.35). Rides in big fields of 14 or more are the standout value angle: 7.3% strikes only just below baseline, but Fair A/E 1.31 and +26.00 to a £1 stake over 192 rides — a record the market has persistently underpriced. Craig Lidster supplies 19% of the rides and edges the rider's average (10.7% vs 8.1%, A/E 1.04) — the partnership beats the margin-free market read. The rider also reads well off a 0-7-day break (14.4%, n=118). The record reads poorly off a break of 180+ days — 0% over 35 rides, 8.1pts below the baseline. The market has consistently overbet the rider off a 61-180-day break: Fair A/E 0.43 across 112 rides (2.7% strike, −60.00 to a £1 stake) — runners there underperform what the price implies. The standout partner of the record: Kats Bob (GB) — 5 wins from 26 rides together. Seasonally, the rider fires Feb–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.

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 Pyle's strike rate?
- William Pyle has won 106 of 1,307 rides since 2008, a strike rate of 8.1% (as at 12 November 2026). Figures are computed from our own results archive.
- Which course does William Pyle do best at?
- Musselburgh by strike rate: 11 wins from 77 rides (14.3%) 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 Pyle ride most for?
- Craig Lidster, with 252 rides since 2008 — 19% of the total. That pairing has won 27 (10.7%).
- Is William Pyle 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 Pyle's Fair A/E?
- 0.84, from 1,304 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.
