KTB Rider Profile

Rides around 20 times a season, almost all on the flat, winning on 9% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.96). Riding last-time-out winners the record reads 15% (40 rides).

The read

It is weakest at Saint-Cloud (FR) (2.5% over 40 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 15% (n=40, Fair A/E 1.26), but rides in big fields of 14 or more have been a poor signal at 4.7% (n=235, Fair A/E 0.81). The market has consistently overbet horses returning fresh after 61+ days: 6.7% strike, Fair A/E 0.74 and −17.30 to a £1 stake over 163 rides — those runners underperform what the price implies. F Rohaut supplies 12% of the rides and matches the rider's average almost exactly (9.4%, A/E 0.62). The rider also reads well off a 15-30-day break (12.5%, n=88). 6 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Criterium de Maisons-Laffitte at Chantilly (FR) (Oct 2020, £70,622). Seasonally, the rider fires Oct–Nov.

Each tile is the record in that situation vs the 8.7% 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.

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.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 12 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 Valentin Seguy's strike rate?
Valentin Seguy has won 39 of 450 rides since 2008, a strike rate of 8.7% (as at 12 November 2026). Figures are computed from our own results archive.
Which course does Valentin Seguy do best at?
Chantilly (FR) by strike rate: 7 wins from 74 rides (9.5%) 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 Valentin Seguy ride most for?
F Rohaut, with 53 rides since 2008 — 12% of the total. That pairing has won 5 (9.4%).
What is Valentin Seguy's Fair A/E?
0.96, from 425 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. Figures as at 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
