Sean Aherne
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 50 runners a season, almost all over hurdles and fences, winning with 5% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.87). New recruits from other yards win at 12% first time out (33 runs).
The record is strongest at Clonmel (10.7%, n=75), clear of the yard's 5.4% baseline. It is weakest at Kilbeggan (0% over 35 runners) — the widest gap in the record. New recruits from other stables on their first run win at 12.1% (n=33, Fair A/E 3.10), but a horse having headgear put back on after a bare run has been a poor signal at 2% (n=49, Fair A/E 0.44). The market has consistently overbet horses returning fresh after 61+ days: 2.7% strike, Fair A/E 0.62 and −97.00 to a £1 stake over 221 runners — those runners underperform what the price implies. Sean O'Keeffe rides 18% of the entries and edges the yard's average (7.9% vs 5.4%, A/E 1.25) — the partnership beats the margin-free market read. The record reads poorly on Good to Firm going — 0% over 33 runners, 5.4pts below the baseline. The stable star of the record: Sheebadiva (IRE) — 6 wins from 27 runs for the yard. Seasonally, the yard fires Jan–Mar.
Yard patterns
the angles behind the record · vs 5.4% baselineEach tile is the record in that situation vs the 5.4% 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 Aherne's strike rate?
- Sean Aherne has won 50 of 926 runners since 2008, a strike rate of 5.4% (as at 8 November 2026). Figures are computed from our own results archive.
- Which course does Sean Aherne do best at?
- Clonmel by strike rate: 8 wins from 75 runners (10.7%) 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 Aherne?
- Sean O'Keeffe, with 165 runners since 2008 — 18% of the total. That pairing has won 13 (7.9%).
- Is Sean Aherne 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 Aherne's Fair A/E?
- 0.87, from 925 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.
