KTB Rider Profile

Rode around 170 times a season, almost all over hurdles and fences, winning on 10% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.11). Riding last-time-out winners the record reads 17% (64 rides). Rode mostly for Seamus Mullins — 47% of rides in the window.

The read

The record is strongest at Towcester (19.6%, n=46), clear of the rider's 10.1% baseline. Rides on last-time-out winners have been a positive signal at 17.2% (n=64, Fair A/E 1.06), but rides in big fields of 14 or more have been a poor signal at 3.4% (n=118, Fair A/E 0.76). Seamus Mullins supplied 47% of the rides and matches the rider's average almost exactly (11.6%, A/E 1.26) — the partnership beats the margin-free market read. The rider also read well beyond 3m (18.5%, n=81). The record read poorly on Good to Soft going — 2.7% over 112 rides, 7.4pts below the baseline. Seasonally, the rider fired Apr–Jun.

Each tile is the record in that situation vs the 10.1% 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 Jimmy Derham's strike rate?
Jimmy Derham has won 69 of 681 rides since 2008, a strike rate of 10.1% (as at 6 November 2026). Figures are computed from our own results archive.
Which course does Jimmy Derham do best at?
Towcester by strike rate: 9 wins from 46 rides (19.6%) 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 Jimmy Derham ride most for?
Seamus Mullins, with 318 rides since 2008 — 47% of the total. That pairing has won 37 (11.6%).
What is Jimmy Derham's Fair A/E?
1.11, from 679 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).
