KTB Rider Profile

Rode around 60 times a season, almost all over hurdles and fences, winning on 2% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.49).

The read

Helen Nelmes supplied 37% of the rides and matches the rider's average almost exactly (2.1%, A/E 0.45). The market has consistently overbet the rider in Chase races: Fair A/E 0.00 across 68 rides (0% strike, −68.00 to a £1 stake) — runners there underperformed what the price implied.

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 2.3% 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.

In our archive from its very first year (2005), so this career almost certainly began earlier than our record does. The figures above count 2005 onwards only — what the archive holds, not a full-career total. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.

Quick answers

What is Owyn Nelmes's strike rate?
Owyn Nelmes has won 6 of 257 rides since 2008, a strike rate of 2.3% (as at 6 November 2026). Figures are computed from our own results archive.
Which course does Owyn Nelmes do best at?
Newton Abbot by strike rate: 1 wins from 38 rides (2.6%) 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.
Which yard does Owyn Nelmes ride most for?
Helen Nelmes, with 94 rides since 2008 — 37% of the total. That pairing has won 2 (2.1%).
What is Owyn Nelmes's Fair A/E?
0.49, from 257 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.
