KTB Rider Profile

Rides around 10 times a season, almost all over hurdles and fences, winning on 4% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.77). The edge shows sharpest with horses returning fresh: 7% off breaks of two months or more (73 runs).

The read

First rides on a horse are the standout value angle: 6% strikes only just above baseline, but Fair A/E 1.28 and +2.80 to a £1 stake over 150 rides — a record the market has persistently underpriced. Robert Collet supplies 38% of the rides and matches the rider's average almost exactly (4%, A/E 0.87). The rider also reads well off a 61-180-day break (7.4%, n=54). The record reads poorly in Chase races — 0% over 42 rides, 4.2pts below the baseline. The market has consistently overbet the rider on Soft going: Fair A/E 0.59 across 170 rides (2.9% strike, −119.70 to a £1 stake) — runners there underperform what the price implies. Seasonally, the rider fires Oct–Nov.

Written from the figures on this page — every claim carries its sample. Descriptive, not a tip.

Each tile is the record in that situation vs the 4.2% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

Descriptive splits ranked by divergence × sample — insight, not instruction. Every angle carries its N; nothing under 30 runs qualifies. Rows within 2pts of the baseline appear only when the market-relative read (Fair A/E) diverges, and show it.

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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 13 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 Alexandre Seigneul's strike rate?
Alexandre Seigneul has won 11 of 264 rides since 2008, a strike rate of 4.2% (as at 13 November 2026). Figures are computed from our own results archive.
Which course does Alexandre Seigneul do best at?
Auteuil (FR) by strike rate: 6 wins from 159 rides (3.8%) since 2008. Read from the 15 courses with the most rides 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.
Which yard does Alexandre Seigneul ride most for?
Robert Collet, with 99 rides since 2008 — 38% of the total. That pairing has won 4 (4%).
What is Alexandre Seigneul's Fair A/E?
0.77, from 258 rides 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.
