KTB Rider Profile

Rides around 90 times a season, almost all over hurdles and fences, winning on 11% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.90). Riding last-time-out winners the record reads 19% (57 rides). Rides mostly for Evan Williams — 95% of rides in the window.

The read

It is weakest at Chepstow (7.2% over 69 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 19.3% (n=57, Fair A/E 1.22), but rides in big fields of 14 or more have been a poor signal at 4.2% (n=48, Fair A/E 0.75). Evan Williams supplies 95% of the rides and matches the rider's average almost exactly (11.1%, A/E 0.91). The rider also reads well off a 8-14-day break (16.7%, n=42) and in Class 4 (14.3%, n=161). The record reads poorly beyond 3m — 5.3% over 38 rides, 5.5pts below the baseline. The market has consistently overbet the rider on Soft going: Fair A/E 0.62 across 123 rides (6.5% strike, −69.50 to a £1 stake) — runners there underperform what the price implies. One Group or Graded win sits in the archive record — the biggest prize the rider has landed: the Betfair Exchange Stayers' Handicap Hurdle at Haydock (Nov 2021, £56,950). The standout partner of the record: Tour Ovalie (FR) — 6 wins from 23 rides together. Seasonally, the rider fires Mar–Apr.

Each tile is the record in that situation vs the 10.8% 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 5 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 Isabel Williams's strike rate?
Isabel Williams has won 50 of 463 rides since 2022, a strike rate of 10.8% (as at 5 November 2026). Figures are computed from our own results archive.
Which course does Isabel Williams do best at?
Newton Abbot by strike rate: 5 wins from 40 rides (12.5%) 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 Isabel Williams ride most for?
Evan Williams, with 441 rides since 2022 — 95% of the total. That pairing has won 49 (11.1%).
What is Isabel Williams's Fair A/E?
0.90, from 462 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 5 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
