KTB Yard Profile

Sends out around 10 runners a season, almost all on the flat, winning with 6% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.77).

KTB at a glance Fires May–Jun Gavin Ryan: 6% from 67
The read

It is weakest at Curragh (2.4% over 41 runners) — the widest gap in the record. In Group and Graded company the record reads poorly at 3.1% (n=32, Fair A/E 0.42). Gavin Ryan rides 26% of the entries and matches the yard's average almost exactly (6%, A/E 0.66). The yard also reads well off a 8-14-day break (13.2%, n=38) and at trips under 6f (12.3%, n=65). The record reads poorly over 1m – 1m1f — 0% over 36 runners, 6.3pts below the baseline. The market has consistently overbet the yard off a 31-60-day break: Fair A/E 0.25 across 53 runners (1.9% strike, −50.38 to a £1 stake) — runners there underperform what the price implies. One Group or Graded win sits in the archive record — the biggest prize the yard has landed: the British EBF 40th Anniversary Maiden Stakes at Goodwood (Aug 2023, £30,924). Seasonally, the yard fires May–Jun.

Each tile is the record in that situation vs the 6.3% 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.

All 52 horses sent out in this window. 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 52 horses listed, 6 arrived from another yard in our archive; 46 had their first archived run for this yard.

12 have since run for another yard, most often for Gemma Tutty (2); 40 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 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 yard’s runners since 7 Oct 2026: top-rated on KTB Rating in 1 run (won 0) · fastest on KTB Speed in 1 run (won 0) · to 7 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 Diego Dias's strike rate?
Diego Dias has won 16 of 255 runners since 2008, a strike rate of 6.3% (as at 4 November 2026). Figures are computed from our own results archive.
Which course does Diego Dias do best at?
Dundalk (AW) by strike rate: 7 wins from 76 runners (9.2%) 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 Diego Dias?
Gavin Ryan, with 67 runners since 2008 — 26% of the total. That pairing has won 4 (6%).
Is Diego Dias in form?
Too few runners in the last 14 days to read — 1 runner, which is not a sample we will draw a conclusion from.
What is Diego Dias's Fair A/E?
0.77, from 254 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 4 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
