KTB Rider Profile

Rides around 310 times a season, almost all on the flat, winning on 9% of them — level with the margin-free market read across five seasons (Fair A/E 0.99). Riding last-time-out winners the record reads 16% (148 rides).

The read

The record is strongest at Newmarket (23.8%, n=42), clear of the rider's 9% baseline. Rides on last-time-out winners have been a positive signal at 16.2% (n=148, Fair A/E 1.15), but horses returning fresh after 61+ days have been a poor signal at 5.9% (n=272, Fair A/E 0.91). Steph Hollinshead supplies 13% of the rides and matches the rider's average almost exactly (9.1%, A/E 1.06) — the partnership beats the margin-free market read. The rider also reads well at trips under 6f (16.8%, n=191). 18 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Commonwealth Cup at Ascot (Jun 2016, £243,853). The standout partner of the record: Justcallmepete (GB) — 10 wins from 44 rides together. Seasonally, the rider fires Aug–Sep.

Each tile is the record in that situation vs the 9% 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.

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 13 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.

KTB’s figures

the forward record · since 5 Oct 2026

KTB’s figures on this rider’s mounts since 13 Oct 2026: the KTB Selection in 1 run (won 0) · fastest on KTB Speed in 4 runs (won 0, 2 did not run) · to 27 Oct 2026.

Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.

Quick answers

What is Dougie Costello's strike rate?
Dougie Costello has won 140 of 1,555 rides since 2022, a strike rate of 9% (as at 13 November 2026). Figures are computed from our own results archive.
Which course does Dougie Costello do best at?
Newmarket by strike rate: 10 wins from 42 rides (23.8%) since 2022. 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 Dougie Costello ride most for?
Steph Hollinshead, with 198 rides since 2022 — 13% of the total. That pairing has won 18 (9.1%).
Is Dougie Costello in form?
Too few rides in the last 14 days to read — 1 ride, which is not a sample we will draw a conclusion from.
What is Dougie Costello's Fair A/E?
0.99, from 1,543 rides with a computed fair probability since 2022. 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).
