What is J Delaunay's strike rate?

J Delaunay has won 58 of 754 runners since 2008, a strike rate of 7.7% (as at 7 November 2026). Figures are computed from our own results archive.

Which course does J Delaunay do best at?

Auteuil (FR) by strike rate: 35 wins from 476 runners (7.4%) 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 J Delaunay?

Wilfried Lajon, with 179 runners since 2008 — 24% of the total. That pairing has won 12 (6.7%).

Is J Delaunay in form?

In the last 14 days: 17 runners, 2 winners, a strike rate of 11.8%. That is above the baseline of 7.7% since 2008.

What is J Delaunay's Fair A/E?

0.90, from 740 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.

KTB Yard Profile

Sends out around 40 runners a season, almost all over hurdles and fences, winning with 8% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.90). The edge shows sharpest with horses returning fresh: 9% off breaks of two months or more (205 runs). 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 4.5% (n=133, Fair A/E 0.67). The market has consistently overbet runners with a claiming rider up: 8.6% strike, Fair A/E 0.85 and −59.20 to a £1 stake over 128 runners — those runners underperform what the price implies. Right now the yard is firing: 2 winners from 17 runners in the last 14 days (11.8%, 4.1pts above the 7.7% baseline). Wilfried Lajon rides 24% of the entries and matches the yard's average almost exactly (6.7%, A/E 0.78). The yard also reads well off a break of 180+ days (13.8%, n=87). The record reads poorly over 1m5f – 2m — 3.1% over 64 runners, 4.6pts below the baseline. 6 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix Magne at Auteuil (FR) (Oct 2023, £53,761).

Each tile is the record in that situation vs the 7.7% 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.

Showing the 60 most-raced of the 247 horses sent out in this window — each ran at least 4 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, 5 arrived from another yard in our archive; 55 had their first archived run for this yard.

6 have since run for another yard; 54 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.
