Sean Byrne
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%".
Sends out around 40 runners a season, across both codes, winning with 6% of them — level with the margin-free market read across the lifetime window (Fair A/E 1.00).
The record is strongest at Cork (15%, n=40) and Leopardstown (12.5%, n=32) — all clear of the yard's 5.8% baseline. It is weakest at Clonmel (0% over 32 runners) — the widest gap in the record. Debutants struggle at 1.8% (n=55, Fair A/E 0.73). The market has consistently overbet horses returning fresh after 61+ days: 2.8% strike, Fair A/E 0.56 and −131.20 to a £1 stake over 176 runners — those runners underperform what the price implies. Sean P Byrne rides 20% of the entries and edges the yard's average (8% vs 5.8%, A/E 1.28) — the partnership beats the margin-free market read. The yard also reads well off a 8-14-day break (13%, n=108). The record reads poorly over 2m5f – 3m — 0% over 41 runners, 5.8pts below the baseline. The market has consistently overbet the yard off a break of 180+ days: Fair A/E 0.28 across 82 runners (1.2% strike, −67.00 to a £1 stake) — runners there underperform what the price implies. 2 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Bar One Racing Ballyhack Handicap Chase at Fairyhouse (Dec 2012, £24,375). The stable star of the record: Lean And Keen (IRE) — 6 wins from 57 runs for the yard. Seasonally, the yard fires Jun–Aug.
Yard patterns
the angles behind the record · vs 5.8% baselineEach tile is the record in that situation vs the 5.8% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races. The same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.

Quick answers
- What is Sean Byrne's strike rate?
- Sean Byrne has won 40 of 689 runners since 2008, a strike rate of 5.8% (as at 11 November 2026). Figures are computed from our own results archive.
- Which course does Sean Byrne do best at?
- Cork by strike rate: 6 wins from 40 runners (15%) since 2008. Read from the 15 courses with the most runners 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.
- Who rides most for Sean Byrne?
- Sean P Byrne, with 138 runners since 2008 — 20% of the total. That pairing has won 11 (8%).
- Is Sean Byrne in form?
- Too few runners in the last 14 days to read — 1 runner, which is not a sample we will draw a conclusion from.
- What is Sean Byrne's Fair A/E?
- 1.00, from 688 runners 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.
