KTB Rider Profile

Rode around 80 times a season, almost all over hurdles and fences, winning on 6% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.80). Rode mostly for Nick Gifford — 43% of rides in the window.

The read

The record is strongest at Fontwell (13.1%, n=61), clear of the rider's 6.4% baseline. Rides in big fields of 14 or more have been a poor signal at 1.6% (n=64, Fair A/E 0.30). The market has consistently overbet claiming rides: 6.6% strike, Fair A/E 0.82 and −64.38 to a £1 stake over 229 rides — those runners underperformed what the price implied. Nick Gifford supplied 43% of the rides and beats the rider's average (11.9% vs 6.4%, A/E 1.07) — the partnership beats the margin-free market read. The rider also read well in NH Flat races (19.4%, n=31) and on Soft going (11.1%, n=45). The record read poorly over 2m5f – 3m — 0% over 50 rides, 6.4pts below the baseline. The market has consistently overbet the rider in Hurdle races: Fair A/E 0.39 across 130 rides (3.1% strike, −51.50 to a £1 stake) — runners there underperformed what the price implied.

Each tile is the record in that situation vs the 6.4% 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.

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.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 28 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 Jay Pemberton's strike rate?
Jay Pemberton has won 15 of 234 rides since 2008, a strike rate of 6.4% (as at 28 October 2026). Figures are computed from our own results archive.
Which course does Jay Pemberton do best at?
Fontwell by strike rate: 8 wins from 61 rides (13.1%) 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 Jay Pemberton ride most for?
Nick Gifford, with 101 rides since 2008 — 43% of the total. That pairing has won 12 (11.9%).
What is Jay Pemberton's Fair A/E?
0.80, from 234 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.
