KTB Yard Profile

Sends out around 10 runners a season, almost all on the flat, winning with 14% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.51). With a claiming rider up the record reads 27% (37 runs).

KTB at a glance Cristian Demuro: 13.4% from 67 Claiming riders: 27%
The read

The record is strongest at Maisons-Laffitte (FR) (22%, n=41), clear of the yard's 14.2% baseline. It is weakest at Deauville (FR) (2.2% over 45 runners) — the widest gap in the record. Runners with a claiming rider up have been a positive signal at 27% (n=37, Fair A/E 2.47), but debutants struggle at 10% (n=40, Fair A/E 1.10). Cristian Demuro rides 33% of the entries and matches the yard's average almost exactly (13.4%, A/E 1.72) — the partnership beats the margin-free market read. The yard also reads well on Good to Soft going (23.1%, n=39). The record reads poorly on Soft going — 5.7% over 35 runners, 8.5pts below the baseline. The stable star of the record: Sweeticon (GB) — 6 wins from 13 runs for the yard.

Each tile is the record in that situation vs the 14.2% 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 54 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 54 horses listed, 14 arrived from another yard in our archive, most often from Gianluca Bietolini (2) and Joel Phelippon (2); 40 had their first archived run for this yard.

24 have since run for another yard, most often for Andrea Marcialis (10); 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.

Top line: the yard'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 12 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 Antonio Marcialis's strike rate?
Antonio Marcialis has won 29 of 204 runners since 2008, a strike rate of 14.2% (as at 12 November 2026). Figures are computed from our own results archive.
Which course does Antonio Marcialis do best at?
Maisons-Laffitte (FR) by strike rate: 9 wins from 41 runners (22%) 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 Antonio Marcialis?
Cristian Demuro, with 67 runners since 2008 — 33% of the total. That pairing has won 9 (13.4%).
What is Antonio Marcialis's Fair A/E?
1.51, from 202 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 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
