What is Ruth Jefferson's strike rate?

Ruth Jefferson has won 87 of 618 runners since 2008, a strike rate of 14.1% (as at 5 November 2026). Figures are computed from our own results archive.

Which course does Ruth Jefferson do best at?

Sedgefield by strike rate: 7 wins from 32 runners (21.9%) 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 Ruth Jefferson?

Jamie Hamilton, with 211 runners since 2008 — 34% of the total. That pairing has won 28 (13.3%).

Is Ruth Jefferson in form?

Too few runners in the last 14 days to read — 4 runners, which is not a sample we will draw a conclusion from.

What is Ruth Jefferson's Fair A/E?

1.14, from 617 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.

KTB Yard Profile

Sends out around 30 runners a season, almost all over hurdles and fences, winning with 14% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.14). Debutants are a strength: 17% on first career starts (47 runs).

The read

The record is strongest at Kelso (21.3%, n=61) and Sedgefield (21.9%, n=32) — all clear of the yard's 14.1% baseline. It is weakest at Southwell (6.3% over 32 runners) — the widest gap in the record. Runners with a claiming rider up have been a poor signal at 6.7% (n=75, Fair A/E 0.71). Jamie Hamilton rides 34% of the entries and matches the yard's average almost exactly (13.3%, A/E 1.16) — the partnership beats the margin-free market read. 6 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Betfair Ascot Chase at Ascot (Feb 2018, £85,827). The stable star of the record: Autumn Return (IRE) — 8 wins from 20 runs for the yard. Seasonally, the yard fires Nov–Jan.

Each tile is the record in that situation vs the 14.1% 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.

Showing the 60 most-raced of the 97 horses sent out in this window — each ran at least 4 times. Horses with fewer runs aren't listed; search finds any horse since 2005. 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.

Where they came from · where they went next

Of the 60 horses listed, 27 arrived from another yard in our archive, most often from Malcolm Jefferson (15) and Michael Dods (2); 33 had their first archived run for this yard.

15 have since run for another yard, most often for Mark Walford (2) and Rebecca Menzies (2); 45 have no later run for another yard in our archive.

Read from each listed horse's whole archived career (2005 onwards), not only this window, and counted over the horses listed above, not the whole string. “First archived run” means our archive holds nothing earlier, not that the horse was unraced. A horse with no later run elsewhere may still be here, be off the track, or have run somewhere our archive does not cover — none of that is asserted.
