KTB Rider Profile

Rides around 400 times a season, almost all over hurdles and fences, winning on 9% of them — beating the margin-free market read across five seasons (Fair A/E 1.04). Riding last-time-out winners the record reads 17% (174 rides).

The read

The record is strongest at Killarney (18.8%, n=69) and Perth (19.4%, n=31) — all clear of the rider's 9.4% baseline. Rides on last-time-out winners have been a positive signal at 16.7% (n=174, Fair A/E 1.08). In Group and Graded company the record are the standout value angle: 12.1% strikes only just above baseline, but Fair A/E 1.42 and +105.01 to a £1 stake over 298 rides — a record the market has persistently underpriced. Joseph Patrick O'Brien supplies 17% of the rides and beats the rider's average (19.9% vs 9.4%, A/E 1.26) — the partnership beats the margin-free market read. The rider also reads well in Class 4 (24.3%, n=70). 45 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the BoyleSports Irish Grand National Chase at Fairyhouse (Apr 2024, £270,000). The standout partner of the record: Home By The Lee (IRE) — 10 wins from 29 rides together. Seasonally, the rider fires Apr–Jun.

Each tile is the record in that situation vs the 9.4% 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.

This filter uses derived form angles computed for 60.4% 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.

KTB’s figures

the forward record · since 5 Oct 2026

KTB’s figures on this rider’s mounts since 6 Oct 2026: the KTB Selection in 4 runs (won 1, 1 did not run) · top-rated on KTB Rating in 3 runs (won 0) · fastest on KTB Speed in 3 runs (won 0) · to 5 Nov 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 J. J. Slevin's strike rate?
J. J. Slevin has won 187 of 1,984 rides since 2022, a strike rate of 9.4% (as at 9 November 2026). Figures are computed from our own results archive.
Which course does J. J. Slevin do best at?
Killarney by strike rate: 13 wins from 69 rides (18.8%) 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 J. J. Slevin ride most for?
Joseph Patrick O'Brien, with 347 rides since 2022 — 17% of the total. That pairing has won 69 (19.9%).
Is J. J. Slevin 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 J. J. Slevin's Fair A/E?
1.04, from 1,984 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 9 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
