KTB Rider Profile

Rides around 30 times a season, winning on 5% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.78).

The read

The record is strongest at Limerick (8.3%, n=72) and Fairyhouse (8.3%, n=36) — all clear of the rider's 4.6% baseline. The market has consistently overbet rides in big fields of 14 or more: 3.2% strike, Fair A/E 0.66 and −183.38 to a £1 stake over 285 rides — those runners underperform what the price implies. Philip Fenton supplies 10% of the rides and matches the rider's average almost exactly (6.2%, A/E 0.80). The rider also reads well in Hurdle races (8.4%, n=95) and over 2m5f – 3m (8.1%, n=99). The record reads poorly on Good to Soft going — 1.4% over 73 rides, 3.2pts below the baseline. 2 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Coolmore N.h. Sires Irish Ebf Mares Flat Race at Navan (Nov 2017, £23,600). Seasonally, the rider fires Nov–Jan.

Each tile is the record in that situation vs the 4.6% 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.

Showing the 60 most-raced of the 448 horses ridden in this window — each ran at least 2 times. Horses with fewer runs aren't listed; search finds any horse since 2005. Runs, wins and places only: a strike rate or a return on a handful of runs is noise, so none is quoted per horse — each horse's full record is on its own page.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 13 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 Mr E P O'Brien's strike rate?
Mr E P O'Brien has won 30 of 654 rides since 2008, a strike rate of 4.6% (as at 13 November 2026). Figures are computed from our own results archive.
Which course does Mr E P O'Brien do best at?
Limerick by strike rate: 6 wins from 72 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 Mr E P O'Brien ride most for?
Philip Fenton, with 65 rides since 2008 — 10% of the total. That pairing has won 4 (6.2%).
Is Mr E P O'Brien in form?
Too few rides in the last 14 days to read — 1 ride, which is not a sample we will draw a conclusion from.
What is Mr E P O'Brien's Fair A/E?
0.78, from 654 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. Figures as at 13 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
