KTB Yard Profile

The read

The record is strongest at Newbury (21.9%, n=32), clear of the yard's 9.6% baseline. Runners with a claiming rider up have been a positive signal at 13.1% (n=337, Fair A/E 1.21), but in Group and Graded company the record reads poorly at 0% (n=34, Fair A/E 0.00). The market has consistently overbet debutants: 2% strike, Fair A/E 0.36 and −41.00 to a £1 stake over 101 runners — those runners underperform what the price implies. Aidan Coleman rides 11% of the entries and matches the yard's average almost exactly (8%, A/E 0.67). The yard also reads well off a 0-7-day break (23%, n=87). The record reads poorly in Class 1 — 0% over 38 runners, 9.6pts below the baseline. The stable star of the record: Flying Verse (GB) — 10 wins from 53 runs for the yard. Seasonally, the yard fires May–Jun.

Each tile is the record in that situation vs the 9.6% 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 181 horses sent out in this window — each ran at least 13 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, 24 arrived from another yard in our archive, most often from Ali Stronge (2) and David O'Meara (2); 36 had their first archived run for this yard.

30 have since run for another yard, most often for Tom Symonds (5) and Adrian Wintle (3); 30 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 3 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.

Quick answers

What is David Dennis's strike rate?
David Dennis has won 199 of 2,070 runners since 2008, a strike rate of 9.6% (as at 3 November 2026). Figures are computed from our own results archive.
Which course does David Dennis do best at?
Market Rasen by strike rate: 14 wins from 82 runners (17.1%) 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 David Dennis?
Aidan Coleman, with 237 runners since 2008 — 11% of the total. That pairing has won 19 (8%).
Is David Dennis 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 David Dennis's Fair A/E?
0.92, from 2,067 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 3 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
