KTB Yard Profile

Sends out around 40 runners a season, across both codes, winning with 5% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.05).

Deterministic profile computed from 681 archived runs (lifetime window) · updated 5 Nov 2026
KTB at a glance Fires Jul–Aug Robbie Colgan: 5.1% from 98 Claiming riders: 5.8%
The read

The record is strongest at Down Royal (16.7%, n=30) and Sligo (9.7%, n=31) — all clear of the yard's 5% baseline. It is weakest at Naas (0% over 41 runners) — the widest gap in the record. A horse having headgear put back on after a bare run has been a poor signal at 0% (n=37, Fair A/E 0.00). Horses returning fresh after 61+ days are the standout value angle: 4.6% strikes only just below baseline, but Fair A/E 1.53 and +6.00 to a £1 stake over 153 runners — a record the market has persistently underpriced. Robbie Colgan rides 14% of the entries and matches the yard's average almost exactly (5.1%, A/E 1.12) — the partnership beats the margin-free market read. The yard also reads well over 1m – 1m1f (10.6%, n=85). The record reads poorly on Heavy going — 0% over 89 runners, 5pts below the baseline. The stable star of the record: Takeachancejimmy (IRE) — 7 wins from 63 runs for the yard. Seasonally, the yard fires Jul–Aug.

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 5% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races. The same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.

Showing the 60 most-raced of the 89 horses sent out in this window — each ran at least 2 times. Horses with fewer runs aren't listed; search finds any horse since 2005. 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.
Where they came from · where they went next

Of the 60 horses listed, 16 arrived from another yard in our archive, most often from Adrian McGuinness (2) and Ms Frances Slevin (2); 44 had their first archived run for this yard.

10 have since run for another yard, most often for Gavin Cromwell (2); 50 have no later run for another yard in our archive.

Read from each listed horse's whole archived career (2005 onwards), not only this window, and counted over the horses listed above, not the whole string. “First archived run” means our archive holds nothing earlier, not that the horse was unraced. A horse with no later run elsewhere may still be here, be off the track, or have run somewhere our archive does not cover — none of that is asserted.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 5 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 yard’s runners since 22 Oct 2026: the KTB Selection in 1 run (won 0) · top-rated on KTB Rating in 1 run (won 0) · fastest on KTB Speed in 1 run (won 0) · 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 Nigel Thomas Slevin's strike rate?
Nigel Thomas Slevin has won 34 of 681 runners since 2008, a strike rate of 5% (as at 5 November 2026). Figures are computed from our own results archive.
Which course does Nigel Thomas Slevin do best at?
Down Royal by strike rate: 5 wins from 30 runners (16.7%) since 2008. Read from the 15 courses with the most runners 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.
Who rides most for Nigel Thomas Slevin?
Robbie Colgan, with 98 runners since 2008 — 14% of the total. That pairing has won 5 (5.1%).
Is Nigel Thomas Slevin in form?
Too few runners in the last 14 days to read — 4 runners, which is not a sample we will draw a conclusion from.
What is Nigel Thomas Slevin's Fair A/E?
1.05, from 681 runners 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. Figures as at 5 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
