Mark Winn
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 300 times a season, almost all on the flat, winning on 11% of them — beating the margin-free market read across five seasons (Fair A/E 1.08). Riding last-time-out winners the record reads 15% (154 rides).
The record is strongest at Carlisle (22.8%, n=57) and Redcar (21.1%, n=71) — all clear of the rider's 10.6% baseline. Rides on last-time-out winners have been a positive signal at 14.9% (n=154, Fair A/E 0.88), but rides in big fields of 14 or more have been a poor signal at 4.4% (n=181, Fair A/E 0.76). The market has consistently overbet horses returning fresh after 61+ days: 5.4% strike, Fair A/E 0.85 and −35.10 to a £1 stake over 166 rides — those runners underperform what the price implies. David O'Meara supplies 36% of the rides and matches the rider's average almost exactly (10.9%, A/E 1.05) — the partnership beats the margin-free market read. The record reads poorly off a break of 180+ days — 1.5% over 67 rides, 9.1pts below the baseline. The standout partner of the record: Abnaa (GB) — 5 wins from 15 rides together. Seasonally, the rider fires May–Jun.
Riding patterns
the angles behind the record · vs 10.6% baselineEach tile is the record in that situation vs the 10.6% 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 Mark Winn's strike rate?
- Mark Winn has won 156 of 1,477 rides since 2022, a strike rate of 10.6% (as at 19 October 2026). Figures are computed from our own results archive.
- Which course does Mark Winn do best at?
- Carlisle by strike rate: 13 wins from 57 rides (22.8%) 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 Mark Winn ride most for?
- David O'Meara, with 534 rides since 2022 — 36% of the total. That pairing has won 58 (10.9%).
- Is Mark Winn in form?
- Too few rides in the last 14 days to read — 14 rides, which is not a sample we will draw a conclusion from.
- What is Mark Winn's Fair A/E?
- 1.08, from 1,469 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.
