Jay Pemberton
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%".
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 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.
Riding patterns
the angles behind the record · vs 6.4% baselineEach 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.

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.
