KTB Rider Profile

Rides around 920 times a season, almost all on the flat, winning on 13% of them — level with the margin-free market read across five seasons (Fair A/E 1.01). Riding last-time-out winners the record reads 18% (476 rides). The rider is in form now — 5 winners in the last fortnight, above their own baseline.

The read

It is weakest at Leicester (2.6% over 38 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 18.1% (n=476, Fair A/E 1.04), but rides in big fields of 14 or more have been a poor signal at 7.2% (n=539, Fair A/E 1.08). Right now the rider is firing: 5 winners from 30 rides in the last 14 days (16.7%, 4.2pts above the 12.5% baseline). John & Sean Quinn supplies 14% of the rides and matches the rider's average almost exactly (11.2%, A/E 0.91). The rider also reads well off a 0-7-day break (21.7%, n=267). 36 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Coolmore Wootton Bassett Nunthorpe Stakes at York (Aug 2022, £302,690). The standout partner of the record: Highfield Princess (FR) — 13 wins from 30 rides together. Seasonally, the rider fires Mar–Apr.

Each tile is the record in that situation vs the 12.5% 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.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 12 Nov 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.

KTB’s figures

the forward record · since 5 Oct 2026

KTB’s figures on this rider’s mounts since 5 Oct 2026: the KTB Selection in 16 runs (won 3) · top-rated on KTB Rating in 8 runs (won 0) · fastest on KTB Speed in 9 runs (won 2) · to 6 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. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.

Quick answers

What is Jason Hart's strike rate?
Jason Hart has won 577 of 4,622 rides since 2022, a strike rate of 12.5% (as at 12 November 2026). Figures are computed from our own results archive.
Which course does Jason Hart do best at?
Musselburgh by strike rate: 26 wins from 158 rides (16.5%) 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 Jason Hart ride most for?
John & Sean Quinn, with 643 rides since 2022 — 14% of the total. That pairing has won 72 (11.2%).
Is Jason Hart in form?
In the last 14 days: 30 rides, 5 winners, a strike rate of 16.7%. That is above the baseline of 12.5% since 2022.
What is Jason Hart's Fair A/E?
1.01, from 4,594 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.
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. Figures as at 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
