Tom Siddall
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%".
Rode around 130 times a season, almost all over hurdles and fences, winning on 6% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.86). Riding last-time-out winners the record reads 13% (63 rides).
The record is strongest at Market Rasen (20.6%, n=34), clear of the rider's 5.6% baseline. It is weakest at Sedgefield (0% over 34 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 12.7% (n=63, Fair A/E 0.98). Horses returning fresh after 61+ days are the standout value angle: 6.3% strikes only just above baseline, but Fair A/E 1.23 and +76.00 to a £1 stake over 271 rides — a record the market has persistently underpriced. Lynn Siddall supplied 19% of the rides and sits below the rider's average (2% vs 5.6%, A/E 0.56). The rider also read well off a 0-7-day break (14.7%, n=34). Seasonally, the rider fired Dec–Feb.
Riding patterns
the angles behind the record · vs 5.6% baselineEach tile is the record in that situation vs the 5.6% 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.

Quick answers
- What is Tom Siddall's strike rate?
- Tom Siddall has won 58 of 1,042 rides since 2008, a strike rate of 5.6% (as at 29 October 2026). Figures are computed from our own results archive.
- Which course does Tom Siddall do best at?
- Market Rasen by strike rate: 7 wins from 34 rides (20.6%) 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 Tom Siddall ride most for?
- Lynn Siddall, with 203 rides since 2008 — 19% of the total. That pairing has won 4 (2%).
- What is Tom Siddall's Fair A/E?
- 0.86, from 1,041 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.
