KTB Rider Profile

Rides around 10 times a season, across both codes, winning on 6% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.04). Rides mostly for Sean Aherne — 50% of rides in the window.

Deterministic profile computed from 212 archived runs (lifetime window) · updated 15 Nov 2026

The read

Horses returning fresh after 61+ days have been a poor signal at 0% (n=48, Fair A/E 0.00). Sean Aherne supplies 50% of the rides and matches the rider's average almost exactly (6.7%, A/E 1.09) — the partnership beats the margin-free market read. The rider also reads well off a 15-30-day break (10.3%, n=39).

Written from the figures on this page — every claim carries its sample. Descriptive, not a tip.

Each tile is the record in that situation vs the 5.7% 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 104 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.

Quick answers

What is Miss S Ahern's strike rate?
Miss S Ahern has won 12 of 212 rides since 2008, a strike rate of 5.7% (as at 15 November 2026). Figures are computed from our own results archive.
Which yard does Miss S Ahern ride most for?
Sean Aherne, with 105 rides since 2008 — 50% of the total. That pairing has won 7 (6.7%).
What is Miss S Ahern's Fair A/E?
1.04, from 211 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 15 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
