KTB Rider Profile

Rode around 30 times a season, almost all on the flat, winning on 16% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.41). The edge shows sharpest with horses returning fresh: 21% off breaks of two months or more (38 runs).

The read

It is weakest at Deauville (12% over 75 rides) — the largest sample in the record, and the widest gap. Horses returning fresh after 61+ days have been a positive signal at 21.1% (n=38, Fair A/E 1.17), but rides in big fields of 14 or more have been a poor signal at 11% (n=91, Fair A/E 1.71). N Clement supplied 35% of the rides and edges the rider's average (21% vs 16.4%, A/E 0.82). The rider also read well over 1m2f – 1m4f (21.7%, n=46) and off a 61-180-day break (21.9%, n=32). The market has also underrated the rider off a 15-30-day break: Fair A/E 1.77 across 58 rides (20.7% strike, +82.20 to a £1 stake). The record read poorly on Standard (AW) going — 11.8% over 76 rides, 4.6pts below the baseline. 3 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Prix Du Muguet at Saint-Cloud (FR) (May 2012, £61,750).

Each tile is the record in that situation vs the 16.4% 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.

In our archive from its very first year (2005), so this career almost certainly began earlier than our record does. The figures above count 2005 onwards only — what the archive holds, not a full-career total. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.

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 6 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 Yannick Letondeur's strike rate?
Yannick Letondeur has won 29 of 177 rides since 2008, a strike rate of 16.4% (as at 6 November 2026). Figures are computed from our own results archive.
Which course does Yannick Letondeur do best at?
Deauville by strike rate: 9 wins from 75 rides (12%) 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 Yannick Letondeur ride most for?
N Clement, with 62 rides since 2008 — 35% of the total. That pairing has won 13 (21%).
What is Yannick Letondeur's Fair A/E?
1.41, from 140 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 6 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
