KTB Rider Profile

Rode around 60 times a season, almost all over hurdles and fences, winning on 11% of them — level with the margin-free market read across the lifetime window (Fair A/E 0.99). Rode mostly for Y-M Porzier — 43% of rides in the window.

The read

In Group and Graded company the record reads poorly at 3% (n=99, Fair A/E 0.38). First rides on a horse are the standout value angle: 9.2% strikes only just below baseline, but Fair A/E 1.55 and +53.00 to a £1 stake over 142 rides — a record the market has persistently underpriced. Y-M Porzier supplied 43% of the rides and matches the rider's average almost exactly (12.2%, A/E 0.81). The rider also read well off a 8-14-day break (17.1%, n=41). The record read poorly in Class 1 — 3% over 99 rides, 7.5pts below the baseline. 4 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Prix Maurice Gillois Grand Steeple-Chase at Auteuil (FR) (Nov 2007, £106,419).

Each tile is the record in that situation vs the 10.5% 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.

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 29 Oct 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 Ray O'Brien's strike rate?
Ray O'Brien has won 36 of 344 rides since 2008, a strike rate of 10.5% (as at 29 October 2026). Figures are computed from our own results archive.
Which course does Ray O'Brien do best at?
Auteuil (FR) by strike rate: 26 wins from 253 rides (10.3%) 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 Ray O'Brien ride most for?
Y-M Porzier, with 148 rides since 2008 — 43% of the total. That pairing has won 18 (12.2%).
What is Ray O'Brien's Fair A/E?
0.99, from 308 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.
