The read

In Group and Graded company the record reads well at 13.7% (n=387, Fair A/E 1.38). Right now the rider is firing: 4 winners from 30 rides in the last 14 days (13.3%, 3.9pts above the 9.4% baseline). Christopher Head supplies 10% of the rides and beats the rider's average (21.6% vs 9.4%, A/E 1.23) — the partnership beats the margin-free market read. The rider also reads well in Class 2 (19.4%, n=31). The record reads poorly in Class 3 — 1.6% over 61 rides, 7.8pts below the baseline. 100 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Queen Elizabeth II Stakes at Ascot (Oct 2023, £655,709). The standout partner of the record: Hooking (GB) — 7 wins from 25 rides together.

Each tile is the record in that situation vs the 9.4% 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.

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.

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 1 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 Aurelien Lemaitre's strike rate?
Aurelien Lemaitre has won 271 of 2,878 rides since 2022, a strike rate of 9.4% (as at 1 November 2026). Figures are computed from our own results archive.
Which course does Aurelien Lemaitre do best at?
Dieppe (FR) by strike rate: 4 wins from 31 rides (12.9%) since 2022. 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 Aurelien Lemaitre ride most for?
Christopher Head, with 283 rides since 2022 — 10% of the total. That pairing has won 61 (21.6%).
Is Aurelien Lemaitre in form?
In the last 14 days: 30 rides, 4 winners, a strike rate of 13.3%. That is above the baseline of 9.4% since 2022.
What is Aurelien Lemaitre's Fair A/E?
1.10, from 2,875 rides with a computed fair probability since 2022. 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 1 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
