What is J Heloury's strike rate?

J Heloury has won 51 of 703 runners since 2008, a strike rate of 7.3% (as at 15 October 2026). Figures are computed from our own results archive.

Which course does J Heloury do best at?

Lyon Parilly by strike rate: 3 wins from 31 runners (9.7%) 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 Heloury?

Ioritz Mendizabal, with 127 runners since 2008 — 18% of the total. That pairing has won 12 (9.4%).

What is J Heloury's Fair A/E?

0.81, from 639 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

Sent out around 80 runners a season, almost all on the flat, winning with 7% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.81).

KTB at a glance Fired Jul–Aug Ioritz Mendizabal: 9.4% from 127

The read

It is weakest at Longchamp (FR) (2.6% over 77 runners) — the widest gap in the record. New recruits from other stables on their first run struggle at 2.7% (n=37, Fair A/E 0.51). The market has consistently overbet horses returning fresh after 61+ days: 5.1% strike, Fair A/E 0.45 and −61.10 to a £1 stake over 138 runners — those runners underperformed what the price implied. Ioritz Mendizabal rode 18% of the entries and edges the yard's average (9.4% vs 7.3%, A/E 1.07) — the partnership beats the margin-free market read. 4 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix d'Aumale at Chantilly (FR) (Sep 2012, £33,333). Seasonally, the yard fired Jul–Aug.

Each tile is the record in that situation vs the 7.3% baseline — descriptive splits with the sample always shown, not tips. 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 60 most-raced of 177 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 60 horses listed, 11 arrived from another yard in our archive, most often from J-L Pelletan (2); 49 had their first archived run for this yard.

35 have since run for another yard, most often for M Boutin (3) and P Chatelain (3); 25 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 15 Oct 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.
