KTB Rider Profile

Rode around 40 times a season, almost all on the flat, winning on 8% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.03). Riding last-time-out winners the record reads 18% (40 rides).

The read

Rides on last-time-out winners have been a positive signal at 17.5% (n=40, Fair A/E 1.26), but rides in big fields of 14 or more have been a poor signal at 0% (n=81, Fair A/E 0.00). John Ryan supplied 19% of the rides and edges the rider's average (12.2% vs 8.1%, A/E 1.50) — the partnership beats the margin-free market read. The rider also read well off a break of 180+ days (16.7%, n=30) and off a 0-7-day break (15.6%, n=32). The record read poorly on Good to Soft going — 0% over 33 rides, 8.1pts below the baseline. The standout partner of the record was Ocean Tempest (GB) — 5 wins from 10 rides together.

Written from the figures on this page — every claim carries its sample. Descriptive, not a tip.

Each tile is the record in that situation vs the 8.1% 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.

In our archive from its very first year (2005), so this career almost certainly began earlier than our record does. The figures above count 2005 onwards only — what the archive holds, not a full-career total. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 28 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 Brett Doyle's strike rate?
Brett Doyle has won 41 of 504 rides since 2008, a strike rate of 8.1% (as at 28 October 2026). Figures are computed from our own results archive.
Which course does Brett Doyle do best at?
Yarmouth by strike rate: 6 wins from 48 rides (12.5%) 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 Brett Doyle ride most for?
John Ryan, with 98 rides since 2008 — 19% of the total. That pairing has won 12 (12.2%).
What is Brett Doyle's Fair A/E?
1.03, from 504 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.
