KTB Rider Profile

Rode around 120 times a season, almost all on the flat, winning on 7% of them — a touch below the margin-free market read across the lifetime window (Fair A/E 0.87). Riding last-time-out winners the record reads 12% (49 rides).

The read

The record is strongest at Catterick (13.3%, n=30), clear of the rider's 7.2% baseline. Rides on last-time-out winners have been a positive signal at 12.2% (n=49, Fair A/E 0.72). David Barron supplied 34% of the rides and matches the rider's average almost exactly (8.6%, A/E 0.85). The rider also read well on Soft going (11.8%, n=51). The record read poorly off a 61-180-day break — 2% over 49 rides, 5.2pts below the baseline. The market has consistently overbet the rider in Class 4: Fair A/E 0.31 across 80 rides (2.5% strike, −64.50 to a £1 stake) — runners there underperformed what the price implied. Seasonally, the rider fired Dec–Feb.

Each tile is the record in that situation vs the 7.2% 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.

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.

Quick answers

What is Dean Heslop's strike rate?
Dean Heslop has won 42 of 580 rides since 2008, a strike rate of 7.2% (as at 6 November 2026). Figures are computed from our own results archive.
Which course does Dean Heslop do best at?
Catterick by strike rate: 4 wins from 30 rides (13.3%) 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 Dean Heslop ride most for?
David Barron, with 198 rides since 2008 — 34% of the total. That pairing has won 17 (8.6%).
What is Dean Heslop's Fair A/E?
0.87, from 575 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 6 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
