KTB Rider Profile

Rides around 40 times a season, almost all on the flat, winning on 3% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.74).

The read

The record is strongest at Saint-Cloud (FR) (6.7%, n=45), clear of the rider's 2.9% baseline. The market has consistently overbet claiming rides: 2.6% strike, Fair A/E 0.68 and −105.20 to a £1 stake over 151 rides — those runners underperform what the price implies. S Kobayashi supplies 26% of the rides and edges the rider's average (7.4% vs 2.9%, A/E 1.29) — the partnership beats the margin-free market read.

Written from the figures on this page — every claim carries its sample. Descriptive, not a tip.

Each tile is the record in that situation vs the 2.9% baseline — descriptive splits with the sample always shown, not tips. 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.

Showing the 60 most-raced of the 108 horses ridden in this window — each ran at least 1 time. Horses with fewer runs aren't listed; search finds any horse since 2005. 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 20 Oct 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 Mme Laura Grosso's strike rate?
Mme Laura Grosso has won 6 of 205 rides since 2022, a strike rate of 2.9% (as at 20 October 2026). Figures are computed from our own results archive.
Which course does Mme Laura Grosso do best at?
Saint-Cloud (FR) by strike rate: 3 wins from 45 rides (6.7%) 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 Mme Laura Grosso ride most for?
S Kobayashi, with 54 rides since 2022 — 26% of the total. That pairing has won 4 (7.4%).
Is Mme Laura Grosso in form?
Too few rides in the last 14 days to read — 5 rides, which is not a sample we will draw a conclusion from.
What is Mme Laura Grosso's Fair A/E?
0.74, from 205 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 20 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
