KTB Rider Profile

Rides around 280 times a season, almost all on the flat, winning on 6% of them — a touch below the margin-free market read across five seasons (Fair A/E 0.88). In Group and Graded company the record reads 8% (231 runs). The rider is quiet just now — 1 winner in the last fortnight, below their own baseline.

The read

The market has consistently overbet rides in big fields of 14 or more: 3.5% strike, Fair A/E 0.68 and −287.60 to a £1 stake over 592 rides — those runners underperform what the price implies. Right now the rider is in a quiet spell: 1 from 30 rides in the last 14 days (3.3%, 3pts below the 6.3% baseline). F Chappet supplies 8% of the rides and beats the rider's average (11.6% vs 6.3%, A/E 1.41) — the partnership beats the margin-free market read. The record reads poorly off a 8-14-day break — 1.5% over 68 rides, 4.8pts below the baseline. The market has consistently overbet the rider off a break of 180+ days: Fair A/E 0.46 across 126 rides (3.2% strike, −59.00 to a £1 stake) — runners there underperform what the price implies. 164 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Qatar Prix du Jockey Club at Chantilly (FR) (Jun 2021, £765,268). The standout partner of the record: Taareef (USA) — 5 wins from 7 rides together. Seasonally, the rider fires Apr–May.

Each tile is the record in that situation vs the 6.3% 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.

This filter uses derived form angles computed for 8.1% of the archive so far (as at 8 Nov 2026); the sample will grow as sequencing completes.
Descriptive splits ranked by divergence × sample — insight, not instruction. Every angle carries its N; nothing under 30 runs qualifies. Rows within 2pts of the baseline appear only when the market-relative read (Fair A/E) diverges, and show it.

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.

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 8 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 Ioritz Mendizabal's strike rate?
Ioritz Mendizabal has won 88 of 1,390 rides since 2022, a strike rate of 6.3% (as at 8 November 2026). Figures are computed from our own results archive.
Which course does Ioritz Mendizabal do best at?
Toulouse (FR) by strike rate: 4 wins from 51 rides (7.8%) 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 Ioritz Mendizabal ride most for?
F Chappet, with 112 rides since 2022 — 8% of the total. That pairing has won 13 (11.6%).
Is Ioritz Mendizabal in form?
In the last 14 days: 30 rides, 1 winner, a strike rate of 3.3%. That is below the baseline of 6.3% since 2022.
What is Ioritz Mendizabal's Fair A/E?
0.88, from 1,388 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 8 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
