Ronald Harris
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%".
Sends out around 310 runners a season, almost all on the flat, winning with 8% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.93).
The record is strongest at Sandown (17.5%, n=63), clear of the yard's 8.4% baseline. Debutants struggle at 2.5% (n=161, Fair A/E 0.54). The market has consistently overbet a horse having headgear put back on after a bare run: 3.3% strike, Fair A/E 0.37 and −133.25 to a £1 stake over 180 runners — those runners underperform what the price implies. Luke Morris rides 19% of the entries and matches the yard's average almost exactly (8.9%, A/E 0.87). 3 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Cisco Hong Kong Sprint Heritage Handicap at Ascot (Jul 2008, £43,617). The stable star of the record: Misaro (GER) — 18 wins from 113 runs for the yard. Seasonally, the yard fires Jan–Mar.
Yard patterns
the angles behind the record · vs 8.4% baselineEach tile is the record in that situation vs the 8.4% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races. The same beliefs, tested across every yard and every GB and Irish race since 2005: Racing myths.

Quick answers
- What is Ronald Harris's strike rate?
- Ronald Harris has won 496 of 5,930 runners since 2008, a strike rate of 8.4% (as at 7 November 2026). Figures are computed from our own results archive.
- Which course does Ronald Harris do best at?
- Brighton by strike rate: 22 wins from 206 runners (10.7%) since 2008. Read from the 15 courses with the most runners 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.
- Who rides most for Ronald Harris?
- Luke Morris, with 1,140 runners since 2008 — 19% of the total. That pairing has won 101 (8.9%).
- Is Ronald Harris in form?
- Too few runners in the last 14 days to read — 1 runner, which is not a sample we will draw a conclusion from.
- What is Ronald Harris's Fair A/E?
- 0.93, from 5,891 runners 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.
