KTB Rider Profile

Rides around 20 times a season, almost all on the flat, winning on 11% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.23). Riding last-time-out winners the record reads 38% (32 rides).

The read

Rides on last-time-out winners have been a positive signal at 37.5% (n=32, Fair A/E 2.05), but rides in big fields of 14 or more have been a poor signal at 6.6% (n=121, Fair A/E 1.35). Roger Varian supplies 12% of the rides and matches the rider's average almost exactly (12.5%, A/E 1.01) — the market has that partnership priced right. Seasonally, the rider fires Jul–Aug.

Each tile is the record in that situation vs the 11.4% 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.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 14 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.

Quick answers

What is Jefferson Smith's strike rate?
Jefferson Smith has won 54 of 473 rides since 2008, a strike rate of 11.4% (as at 14 November 2026). Figures are computed from our own results archive.
Which course does Jefferson Smith do best at?
Deauville (FR) by strike rate: 15 wins from 92 rides (16.3%) 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 Jefferson Smith ride most for?
Roger Varian, with 56 rides since 2008 — 12% of the total. That pairing has won 7 (12.5%).
What is Jefferson Smith's Fair A/E?
1.23, from 454 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.
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 14 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
