KTB Rider Profile

Rode around 10 times a season, almost all over hurdles and fences, winning on 15% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.24). The edge shows sharpest with horses returning fresh: 17% off breaks of two months or more (42 runs). Rode mostly for David Rees — 47% of rides in the window.

The read

Claiming rides are the standout value angle: 15.2% strikes only just above baseline, but Fair A/E 1.28 and +14.30 to a £1 stake over 112 rides — a record the market has persistently underpriced. David Rees supplied 47% of the rides and beats the rider's average (21.8% vs 14.5%, A/E 2.14) — the partnership beats the margin-free market read. The rider also read well in Class 5 (19.6%, n=46). The record read poorly over 2m1f – 2m4f — 6.1% over 33 rides, 8.4pts below the baseline.

Each tile is the record in that situation vs the 14.5% 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.

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 Mr J F Mathias's strike rate?
Mr J F Mathias has won 17 of 117 rides since 2008, a strike rate of 14.5% (as at 6 November 2026). Figures are computed from our own results archive.
Which yard does Mr J F Mathias ride most for?
David Rees, with 55 rides since 2008 — 47% of the total. That pairing has won 12 (21.8%).
What is Mr J F Mathias's Fair A/E?
1.24, from 116 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).
