The read

The market has consistently overbet rides in big fields of 14 or more: 1% strike, Fair A/E 0.22 and −92.50 to a £1 stake over 102 rides — those runners underperform what the price implies. Ross O'Sullivan supplies 51% of the rides and edges the rider's average (4.6% vs 2.3%, A/E 0.58). The market has consistently overbet the rider in Flat races: Fair A/E 0.00 across 97 rides (0% strike, −97.00 to a £1 stake) — runners there underperform what the price implies.

Each tile is the record in that situation vs the 2.3% 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 67 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 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 Shane Markey's strike rate?
Shane Markey has won 4 of 172 rides since 2008, a strike rate of 2.3% (as at 13 November 2026). Figures are computed from our own results archive.
Which course does Shane Markey do best at?
Dundalk (AW) by strike rate: 0 wins from 42 rides (0%) 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 Shane Markey ride most for?
Ross O'Sullivan, with 87 rides since 2008 — 51% of the total. That pairing has won 4 (4.6%).
Is Shane Markey in form?
Too few rides in the last 14 days to read — 5 rides, which is not a sample we will draw a conclusion from.
What is Shane Markey's Fair A/E?
0.40, from 172 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).
