No rides from 1 Jan 2008, where our aggregate statistics normally begin — showing the full archive record instead, 28 May 2005 to 11 Jun 2006. Figures that need a horse's earlier runs (debuts, time since a run, first-time headgear, new connections, last-time-out winners) are left out: for runs this early our archive cannot see what came before.

Each tile is the record in that situation vs the 0% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. Claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races. Tiles that depend on a horse's earlier runs (debuts, time off, first-time headgear, new connections, last-time-out winners) are not shown on an archive-era record: for runs this early our archive cannot see what came before.

Fair A/E per band is the tell: near 1.00 the market had it priced right; well above, the wins came where the market didn't expect them.

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 2005, 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.

The record

all 5 archived runs · newest first

Every one of J-R Dubosc's 5 archived rides, from 28 May 2005 to 11 June 2006, newest first — no winners among them.

Best finish: 4th of 8 — Olaya (USA), Marseille Borely (FR), 28 May 2005.

Drawn from the whole archive (2005 onwards), so it can include runs outside the window the header statistics cover. Non-runners are not listed. A finish shown in letters is a non-completion (F fell · UR unseated · PU pulled up · BD brought down).

Quick answers

What is J-R Dubosc's strike rate?
J-R Dubosc has won 0 of 5 rides between 2005 and 2006, a strike rate of 0% (as at 6 November 2026). Figures are computed from our own results archive. A small sample — fewer than 30 rides, so read the count before the percentage. Our archive begins in 2005, so anything earlier is not counted.
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). This profile has no runs from 2008, so every figure on this page counts from the start of the archive instead.
