KTB Rider Profile

Rode around 40 times a season, almost all over hurdles and fences, winning on 5% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.86). Riding last-time-out winners the record reads 7% (30 rides).

The read

Rides in big fields of 14 or more have been a poor signal at 1% (n=100, Fair A/E 0.24). The market has consistently overbet horses returning fresh after 61+ days: 5.2% strike, Fair A/E 0.78 and −35.80 to a £1 stake over 135 rides — those runners underperformed what the price implied. Dianne Sayer supplied 23% of the rides and matches the rider's average almost exactly (6.2%, A/E 1.13) — the partnership beats the margin-free market read. The rider also read well in Class 5 (8.6%, n=198) and in Chase races (8.5%, n=142). The record read poorly in Class 3 — 0% over 33 rides, 4.9pts below the baseline. The market has consistently overbet the rider off a 8-14-day break: Fair A/E 0.23 across 100 rides (1% strike, −91.00 to a £1 stake) — runners there underperformed what the price implied.

Each tile is the record in that situation vs the 4.9% baseline — descriptive splits with the sample always shown, not tips. 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 22 Oct 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 Colm McCormack's strike rate?
Colm McCormack has won 28 of 571 rides since 2008, a strike rate of 4.9% (as at 22 October 2026). Figures are computed from our own results archive.
Which course does Colm McCormack do best at?
Sedgefield by strike rate: 6 wins from 92 rides (6.5%) 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 Colm McCormack ride most for?
Dianne Sayer, with 129 rides since 2008 — 23% of the total. That pairing has won 8 (6.2%).
What is Colm McCormack's Fair A/E?
0.86, from 564 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.
