KTB Rider Profile

Rides around 10 times a season, almost all over hurdles and fences, winning on 3% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.69). The edge shows sharpest with horses returning fresh: 4% off breaks of two months or more (50 runs).

The read

The market has consistently overbet claiming rides: 2.5% strike, Fair A/E 0.69 and −103.00 to a £1 stake over 162 rides — those runners underperform what the price implies. David J McGrath supplies 32% of the rides and matches the rider's average almost exactly (3.8%, A/E 0.89). The rider also reads well in Chase races (6.4%, n=47). The market has consistently overbet the rider in Hurdle races: Fair A/E 0.35 across 94 rides (1.1% strike, −86.00 to a £1 stake) — runners there underperform what the price implies.

Each tile is the record in that situation vs the 2.5% 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.

Quick answers

What is Derek Thomas McGrath's strike rate?
Derek Thomas McGrath has won 4 of 163 rides since 2008, a strike rate of 2.5% (as at 13 November 2026). Figures are computed from our own results archive.
Which yard does Derek Thomas McGrath ride most for?
David J McGrath, with 52 rides since 2008 — 32% of the total. That pairing has won 2 (3.8%).
What is Derek Thomas McGrath's Fair A/E?
0.69, from 163 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).
