KTB Rider Profile

Rode around 40 times a season, almost all over hurdles and fences, winning on 12% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.21). First rides on a horse are a strength: 14% on the first captured pairing (124 rides). Rode mostly for Martin Keighley — 54% of rides in the window.

The read

First rides on a horse are the standout value angle: 13.7% strikes only just above baseline, but Fair A/E 1.51 and +13.24 to a £1 stake over 124 rides — a record the market has persistently underpriced. Martin Keighley supplied 54% of the rides and matches the rider's average almost exactly (10.9%, A/E 1.28) — the partnership beats the margin-free market read. The rider also read well in Class 3 (15.2%, n=33). The record read poorly off a 61-180-day break — 4.8% over 42 rides, 6.9pts 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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 6 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 Harry Stock's strike rate?
Harry Stock has won 30 of 256 rides since 2008, a strike rate of 11.7% (as at 6 November 2026). Figures are computed from our own results archive.
Which yard does Harry Stock ride most for?
Martin Keighley, with 137 rides since 2008 — 54% of the total. That pairing has won 15 (10.9%).
What is Harry Stock's Fair A/E?
1.21, from 256 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 6 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
