KTB Rider Profile

Rides around 10 times a season, almost all on the flat, winning on 4% of them.

Deterministic profile computed from 103 archived runs (lifetime window) · updated 5 Nov 2026
KTB at a glance Fresh horses: 5.3%
The read

The record is strongest at Chantilly (FR) (7%, n=43), clear of the rider's 3.9% baseline. The record reads poorly over 1m – 1m1f — 0% over 39 rides, 3.9pts below the baseline. The market has consistently overbet the rider on Standard (AW) going: Fair A/E 0.52 across 50 rides (2% strike, −41.90 to a £1 stake) — runners there underperform what the price implies.

Each tile is the record in that situation vs the 3.9% 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.

Showing the 60 most-raced of the 64 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 5 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 Stephen Hellyn's strike rate?
Stephen Hellyn has won 4 of 103 rides since 2008, a strike rate of 3.9% (as at 5 November 2026). Figures are computed from our own results archive.
Which course does Stephen Hellyn do best at?
Chantilly (FR) by strike rate: 3 wins from 43 rides (7%) 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.
What is Stephen Hellyn's Fair A/E?
1.03, from 99 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 5 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
