KTB Rider Profile

Rides around 30 times a season, almost all over hurdles and fences, winning on 5% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.88).

The read

Ms M Flynn supplies 29% of the rides and sits below the rider's average (0% vs 4.7%, A/E 0.00). The rider also reads well off a 15-30-day break (10%, n=50). The market has consistently overbet the rider in Hurdle races: Fair A/E 0.71 across 147 rides (3.4% strike, −90.50 to a £1 stake) — runners there underperform what the price implies.

Each tile is the record in that situation vs the 4.7% 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.

Showing the 60 most-raced of the 88 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.

KTB’s figures on this rider’s mounts since 17 Oct 2026: fastest on KTB Speed in 1 run (won 0) · to 17 Oct 2026.

Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.

Quick answers

What is Ethan O'Sullivan's strike rate?
Ethan O'Sullivan has won 8 of 172 rides since 2022, a strike rate of 4.7% (as at 5 November 2026). Figures are computed from our own results archive.
Which yard does Ethan O'Sullivan ride most for?
Ms M Flynn, with 50 rides since 2022 — 29% of the total. That pairing has won 0 (0%).
Is Ethan O'Sullivan in form?
Too few rides in the last 14 days to read — 4 rides, which is not a sample we will draw a conclusion from.
What is Ethan O'Sullivan's Fair A/E?
0.88, from 172 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 5 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
