KTB Rider Profile

Rides around 220 times a season, almost all on the flat, winning on 10% of them — level with the margin-free market read across five seasons (Fair A/E 1.01). Riding last-time-out winners the record reads 16% (126 rides). Rides mostly for Grant Tuer — 53% of rides in the window.

The read

It is weakest at York (2.4% over 41 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 15.9% (n=126, Fair A/E 0.97), but rides in big fields of 14 or more have been a poor signal at 5.7% (n=141, Fair A/E 1.00). Grant Tuer supplies 53% of the rides and matches the rider's average almost exactly (11.5%, A/E 1.03) — the market has that partnership priced right. The rider also reads well off a 0-7-day break (20.5%, n=78). The standout partner of the record: Bellarchi (IRE) — 6 wins from 22 rides together. Seasonally, the rider fires Jun–Jul.

Each tile is the record in that situation vs the 10.4% 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.

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 4 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 10 Oct 2026: the KTB Selection in 2 runs (won 0) · top-rated on KTB Rating in 2 runs (won 0) · fastest on KTB Speed in 3 runs (won 1) · to 26 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 Oliver Stammers's strike rate?
Oliver Stammers has won 115 of 1,109 rides since 2022, a strike rate of 10.4% (as at 4 November 2026). Figures are computed from our own results archive.
Which course does Oliver Stammers do best at?
Wolverhampton (AW) by strike rate: 15 wins from 99 rides (15.2%) 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 Oliver Stammers ride most for?
Grant Tuer, with 585 rides since 2022 — 53% of the total. That pairing has won 67 (11.5%).
Is Oliver Stammers in form?
Too few rides in the last 14 days to read — 12 rides, which is not a sample we will draw a conclusion from.
What is Oliver Stammers's Fair A/E?
1.01, from 1,105 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 4 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
