KTB Rider Profile

Rides around 130 times a season, almost all on the flat, winning on 12% of them — level with the margin-free market read across five seasons (Fair A/E 1.02). Riding last-time-out winners the record reads 20% (95 rides).

The read

The record is strongest at Hamilton (22.5%, n=40), clear of the rider's 12% baseline. Rides on last-time-out winners have been a positive signal at 20% (n=95, Fair A/E 1.16), but rides in big fields of 14 or more have been a poor signal at 4.9% (n=102, Fair A/E 0.88). K R Burke supplies 23% of the rides and matches the rider's average almost exactly (12.6%, A/E 0.89). The rider also reads well off a 8-14-day break (18.1%, n=149). The record reads poorly off a 61-180-day break — 2.4% over 42 rides, 9.6pts below the baseline. The market has consistently overbet the rider in Class 2: Fair A/E 0.63 across 65 rides (4.6% strike, −17.25 to a £1 stake) — runners there underperform what the price implies. 2 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Prix de l'Abbaye de Longchamp Longines at Longchamp (FR) (Oct 2026, £199,990). The standout partner of the record: Hurt You Never (IRE) — 6 wins from 22 rides together. Seasonally, the rider fires May–Jun.

Each tile is the record in that situation vs the 12% 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.

This filter uses derived form angles computed for 60.9% of the archive so far (as at 9 Nov 2026); the sample will grow as sequencing completes.
Descriptive splits ranked by divergence × sample — insight, not instruction. Every angle carries its N; nothing under 30 runs qualifies. Rows within 2pts of the baseline appear only when the market-relative read (Fair A/E) diverges, and show it.

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 9 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 7 Oct 2026: the KTB Selection in 6 runs (won 2) · top-rated on KTB Rating in 7 runs (won 2) · fastest on KTB Speed in 4 runs (won 0) · to 20 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 Jack Nicholls's strike rate?
Jack Nicholls has won 76 of 632 rides since 2022, a strike rate of 12% (as at 9 November 2026). Figures are computed from our own results archive.
Which course does Jack Nicholls do best at?
Hamilton by strike rate: 9 wins from 40 rides (22.5%) 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 Jack Nicholls ride most for?
K R Burke, with 143 rides since 2022 — 23% of the total. That pairing has won 18 (12.6%).
What is Jack Nicholls's Fair A/E?
1.02, from 631 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.
