KTB Rider Profile

Rode around 520 times a season, almost all over hurdles and fences, winning on 19% of them — beating the margin-free market read across the lifetime window (Fair A/E 1.05). Riding last-time-out winners the record reads 27% (722 rides). Rode mostly for Donald McCain — 59% of rides in the window.

The read

It is weakest at Cheltenham (5.8% over 139 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 27% (n=722, Fair A/E 1.05), but in Group and Graded company the record reads poorly at 6.6% (n=151, Fair A/E 0.64). Donald McCain supplied 59% of the rides and matches the rider's average almost exactly (20.7%, A/E 1.01) — the market has that partnership priced right. The record read poorly in Class 1 — 8.5% over 317 rides, 10.3pts below the baseline. 11 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the John Smith's Grand National Chase at Aintree (Apr 2011, £535,135). The standout partner of the record was Peddlers Cross (IRE) — 9 wins from 15 rides together. Seasonally, the rider fired Nov–Dec.

Each tile is the record in that situation vs the 18.8% baseline — descriptive splits with the sample always shown, not tips. 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.

In our archive from its very first year (2005), so this career almost certainly began earlier than our record does. The figures above count 2005 onwards only — what the archive holds, not a full-career total. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.

Beneath it: every run by that sire's progeny in our archive since 2008, as at 15 Oct 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 Jason Maguire's strike rate?
Jason Maguire has won 783 of 4,171 rides since 2008, a strike rate of 18.8% (as at 15 October 2026). Figures are computed from our own results archive.
Which course does Jason Maguire do best at?
Sedgefield by strike rate: 46 wins from 167 rides (27.5%) 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 Jason Maguire ride most for?
Donald McCain, with 2,468 rides since 2008 — 59% of the total. That pairing has won 512 (20.7%).
What is Jason Maguire's Fair A/E?
1.05, from 4,163 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 15 October 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
