What is Joanna Mason's strike rate?

Joanna Mason has won 279 of 2,775 rides since 2022, a strike rate of 10.1% (as at 12 November 2026). Figures are computed from our own results archive.

Which course does Joanna Mason do best at?

Pontefract by strike rate: 20 wins from 132 rides (15.2%) since 2022. 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 Joanna Mason ride most for?

Michael & David Easterby, with 994 rides since 2022 — 36% of the total. That pairing has won 106 (10.7%).

Is Joanna Mason in form?

In the last 14 days: 18 rides, 3 winners, a strike rate of 16.7%. That is above the baseline of 10.1% since 2022.

What is Joanna Mason's Fair A/E?

1.00, from 2,764 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.

KTB Rider Profile

Rides around 560 times a season, almost all on the flat, winning on 10% of them — level with the margin-free market read across five seasons (Fair A/E 1.00). Riding last-time-out winners the record reads 17% (285 rides). The rider is in form now — 3 winners in the last fortnight, above their own baseline.

The read

The record is strongest at Pontefract (15.2%, n=132), clear of the rider's 10.1% baseline. It is weakest at Chelmsford City (AW) (2.5% over 40 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 16.8% (n=285, Fair A/E 1.08), but horses returning fresh after 61+ days have been a poor signal at 6.9% (n=361, Fair A/E 0.98). Rides in big fields of 14 or more are the standout value angle: 8.9% strikes only just below baseline, but Fair A/E 1.39 and +21.57 to a £1 stake over 326 rides — a record the market has persistently underpriced. Right now the rider is firing: 3 winners from 18 rides in the last 14 days (16.7%, 6.6pts above the 10.1% baseline). Michael & David Easterby supplies 36% of the rides and matches the rider's average almost exactly (10.7%, A/E 0.99) — the market has that partnership priced right. The rider also reads well off a 0-7-day break (15%, n=187). The record reads poorly off a 61-180-day break — 5.4% over 204 rides, 4.7pts below the baseline. 3 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Sky Bet Constantine Handicap Stakes at York (Aug 2026, £69,579). The standout partner of the record: Tapis Libre (GB) — 10 wins from 34 rides together. Seasonally, the rider fires Dec–Jan.

Each tile is the record in that situation vs the 10.1% 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.

KTB’s figures on this rider’s mounts since 5 Oct 2026: the KTB Selection in 4 runs (won 2) · top-rated on KTB Rating in 9 runs (won 4) · fastest on KTB Speed in 6 runs (won 1, 1 did not run) · to 7 Nov 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.
