KTB Rider Profile

Rides around 80 times a season, almost all on the flat, winning on 7% of them — beating the margin-free market read across five seasons (Fair A/E 1.10).

The read

The record is strongest at Chantilly (FR) (12.2%, n=41), clear of the rider's 6.7% baseline. It is weakest at Deauville (AW) (2.9% over 137 rides) — the largest sample in the record, and the widest gap. Horses returning fresh after 61+ days are the standout value angle: 7.6% strikes only just above baseline, but Fair A/E 1.75 and +70.90 to a £1 stake over 105 rides — a record the market has persistently underpriced. T Poche supplies 15% of the rides and matches the rider's average almost exactly (4.8%, A/E 1.11) — the partnership beats the margin-free market read. The rider also reads well on Soft going (10.5%, n=95) and in Class 4 (10.4%, n=48). 6 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Grand Handicap de Chantilly at Chantilly (FR) (Jun 2022, £29,412).

Each tile is the record in that situation vs the 6.7% 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.

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 Christopher Grosbois's strike rate?
Christopher Grosbois has won 27 of 401 rides since 2022, a strike rate of 6.7% (as at 12 November 2026). Figures are computed from our own results archive.
Which course does Christopher Grosbois do best at?
Chantilly (FR) by strike rate: 5 wins from 41 rides (12.2%) 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 Christopher Grosbois ride most for?
T Poche, with 62 rides since 2022 — 15% of the total. That pairing has won 3 (4.8%).
Is Christopher Grosbois in form?
In the last 14 days: 27 rides, 2 winners, a strike rate of 7.4%. That is in line with the baseline of 6.7% since 2022.
What is Christopher Grosbois's Fair A/E?
1.10, from 399 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 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
