KTB Yard Profile

Sends out around 20 runners a season, almost all on the flat, winning with 10% of them — level with the margin-free market read across the lifetime window (Fair A/E 0.98). The yard is in form now — 2 winners in the last fortnight, above its own baseline.

The read

In Group and Graded company the record reads poorly at 5.8% (n=52, Fair A/E 0.67). Right now the yard is firing: 2 winners from 15 runners in the last 14 days (13.3%, 3.2pts above the 10.1% baseline). J Moutard rides 15% of the entries and matches the yard's average almost exactly (9.5%, A/E 1.04) — the partnership beats the margin-free market read. The yard also reads well off a 15-30-day break (16.6%, n=151) and on Good going (15%, n=40). The record reads poorly off a 8-14-day break — 4.2% over 48 runners, 5.9pts below the baseline. The market has consistently overbet the yard off a 31-60-day break: Fair A/E 0.51 across 88 runners (4.5% strike, −64.60 to a £1 stake) — runners there underperform what the price implies. 3 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Super Handicap de Reouverture at Longchamp (FR) (Apr 2026, £41,739). Seasonally, the yard fires Mar–Apr.

Each tile is the record in that situation vs the 10.1% 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 82 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, 36 arrived from another yard in our archive, most often from Gianluca Bietolini (4) and A Schutz (2); 24 had their first archived run for this yard.

10 have since run for another yard; 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.

Quick answers

What is Gerald Mosse's strike rate?
Gerald Mosse has won 42 of 417 runners since 2008, a strike rate of 10.1% (as at 1 November 2026). Figures are computed from our own results archive.
Which course does Gerald Mosse do best at?
Saint-Cloud by strike rate: 5 wins from 45 runners (11.1%) 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 Gerald Mosse?
J Moutard, with 63 runners since 2008 — 15% of the total. That pairing has won 6 (9.5%).
Is Gerald Mosse in form?
In the last 14 days: 15 runners, 2 winners, a strike rate of 13.3%. That is above the baseline of 10.1% since 2008.
What is Gerald Mosse's Fair A/E?
0.98, from 416 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 1 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
