KTB Rider Profile

Rides around 370 times a season, almost all over hurdles and fences, winning on 13% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.04). Riding last-time-out winners the record reads 20% (866 rides).

The read

The record is strongest at Perth (21.1%, n=76), clear of the rider's 12.8% baseline. Rides on last-time-out winners have been a positive signal at 20.2% (n=866, Fair A/E 1.06), but rides in big fields of 14 or more have been a poor signal at 7.1% (n=1,399, Fair A/E 1.01). Philip Hobbs supplies 25% of the rides and matches the rider's average almost exactly (13.9%, A/E 0.96). The rider also reads well off a 0-7-day break (23.5%, n=170). 38 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Coral Welsh Grand National Handicap Chase at Chepstow (Dec 2018, £85,425). The standout partner of the record: Pure Faith (IRE) — 8 wins from 28 rides together. Seasonally, the rider fires Jun–Sep.

Each tile is the record in that situation vs the 12.8% 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.

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.

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 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 Tom O'Brien's strike rate?
Tom O'Brien has won 897 of 7,031 rides since 2008, a strike rate of 12.8% (as at 13 November 2026). Figures are computed from our own results archive.
Which course does Tom O'Brien do best at?
Newton Abbot by strike rate: 64 wins from 387 rides (16.5%) 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 Tom O'Brien ride most for?
Philip Hobbs, with 1,786 rides since 2008 — 25% of the total. That pairing has won 249 (13.9%).
What is Tom O'Brien's Fair A/E?
1.04, from 7,025 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).
