KTB Rider Profile

Rides around 30 times a season, winning on 12% of them — level with the margin-free market read across five seasons (Fair A/E 0.98).

The read

Rides in big fields of 14 or more have been a poor signal at 1.5% (n=65, Fair A/E 0.20). The rider also reads well over 1m5f – 2m (18.3%, n=60) and on Soft going (16.1%, n=56). The record reads poorly over 2m1f – 2m4f — 4.1% over 49 rides, 7.6pts below the baseline.

Each tile is the record in that situation vs the 11.7% 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 124 horses ridden in this window — each ran at least 1 time. 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 12 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 Miss M O'Sullivan's strike rate?
Miss M O'Sullivan has won 19 of 163 rides since 2022, a strike rate of 11.7% (as at 12 November 2026). Figures are computed from our own results archive.
What is Miss M O'Sullivan's Fair A/E?
0.98, from 163 rides with a computed fair probability since 2022. 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 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
