KTB Rider Profile

Rode around 100 times a season, almost all over hurdles and fences, winning on 4% of them — level with the margin-free market read across the lifetime window (Fair A/E 1.02). When claiming the record reads 6% (98 rides).

The read

The record is strongest at Wexford (9.3%, n=43) and Downpatrick (8.3%, n=48) — all clear of the rider's 4.2% baseline. It is weakest at Punchestown (1.1% over 89 rides) — the widest gap in the record. Horses returning fresh after 61+ days are the standout value angle: 5.6% strikes only just above baseline, but Fair A/E 1.67 and +6.00 to a £1 stake over 306 rides — a record the market has persistently underpriced. The market has consistently overbet first rides on a horse: 2.5% strike, Fair A/E 0.85 and −429.00 to a £1 stake over 693 rides — those runners underperformed what the price implied. J F O'Shea supplied 16% of the rides and beats the rider's average (9.7% vs 4.2%, A/E 1.37) — the partnership beats the margin-free market read. The rider also read well off a 61-180-day break (8%, n=174) and on Good to Firm going (8.2%, n=134). 2 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the ISF EBF Lombardstown Mares Novice Chase at Cork (Dec 2006, £26,040). The standout partner of the record was Gudnis Gracious Me (IRE) — 6 wins from 37 rides together. Seasonally, the rider fired Feb–Mar.

Each tile is the record in that situation vs the 4.2% 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.

In our archive from its very first year (2005), so this career almost certainly began earlier than our record does. The figures above count 2005 onwards only — what the archive holds, not a full-career total. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 6 Nov 2026 — what they have done, not a forecast. A going or a distance is named only where at least 100 progeny runs sit 3 or more points from the sire's own win rate. Distance bands cover Flat and jumps together.

Quick answers

What is Sean McDermott's strike rate?
Sean McDermott has won 55 of 1,324 rides since 2008, a strike rate of 4.2% (as at 6 November 2026). Figures are computed from our own results archive.
Which course does Sean McDermott do best at?
Downpatrick by strike rate: 4 wins from 48 rides (8.3%) 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 Sean McDermott ride most for?
J F O'Shea, with 217 rides since 2008 — 16% of the total. That pairing has won 21 (9.7%).
What is Sean McDermott's Fair A/E?
1.02, from 1,324 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.
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%". Three sample sizes are reported and never blended: runs (n), the ROI basis (n at SP), and the fair-A/E basis (n with a computed fair probability).

Strike rate is wins over all runs (n). ROI is £1 level stakes at SP over runs with a parseable price (n at SP). Fair A/E is wins over margin-stripped market expectation, over runs with a computed fair probability (n fair). The three Ns can legitimately differ and are always shown.
