KTB Yard Profile

Sends out around 20 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 0.93).

Deterministic profile computed from 465 archived runs (lifetime window) · updated 30 Oct 2026
KTB at a glance Marc-Olivier Belley: 16.9% from 83
The read

It is weakest at Auteuil (FR) (5% over 200 runners) — the largest sample in the record, and the widest gap. A horse in first-time headgear has been a poor signal at 4.1% (n=49, Fair A/E 0.83). Runners with a claiming rider up are the standout value angle: 7.8% strikes only just below baseline, but Fair A/E 1.37 and +13.40 to a £1 stake over 102 runners — a record the market has persistently underpriced. The market has consistently overbet horses returning fresh after 61+ days: 7% strike, Fair A/E 0.64 and −58.70 to a £1 stake over 157 runners — those runners underperform what the price implies. Marc-Olivier Belley rides 18% of the entries and beats the yard's average (16.9% vs 8.2%, A/E 1.58) — the partnership beats the margin-free market read. 6 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Prix Romati at Compiegne (FR) (May 2023, £60,133). The stable star of the record: Rusquela (FR) — 5 wins from 9 runs for the yard.

Each tile is the record in that situation vs the 8.2% 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.

Showing the 60 most-raced of the 122 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, 3 arrived from another yard in our archive; 57 had their first archived run for this yard.

10 have since run for another yard, most often for M Seror (2); 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 B Lefevre's strike rate?
B Lefevre has won 38 of 465 runners since 2008, a strike rate of 8.2% (as at 30 October 2026). Figures are computed from our own results archive.
Which course does B Lefevre do best at?
Enghien (FR) by strike rate: 7 wins from 67 runners (10.4%) 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 B Lefevre?
Marc-Olivier Belley, with 83 runners since 2008 — 18% of the total. That pairing has won 14 (16.9%).
What is B Lefevre's Fair A/E?
0.93, from 418 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 30 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
