What is Jamie Spencer's strike rate?

Jamie Spencer has won 122 of 1,115 rides since 2022, a strike rate of 10.9% (as at 11 November 2026). Figures are computed from our own results archive.

Which course does Jamie Spencer do best at?

Lingfield (AW) by strike rate: 12 wins from 47 rides (25.5%) 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 Jamie Spencer ride most for?

David Simcock, with 218 rides since 2022 — 20% of the total. That pairing has won 25 (11.5%).

What is Jamie Spencer's Fair A/E?

0.86, from 1,109 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.

The read

The record is strongest at Lingfield (AW) (25.5%, n=47), clear of the rider's 10.9% baseline. Rides on last-time-out winners have been a positive signal at 14.6% (n=157, Fair A/E 0.91), but rides in big fields of 14 or more have been a poor signal at 6% (n=251, Fair A/E 1.03). The market has consistently overbet horses returning fresh after 61+ days: 7.7% strike, Fair A/E 0.58 and −106.61 to a £1 stake over 222 rides — those runners underperform what the price implies. David Simcock supplies 20% of the rides and matches the rider's average almost exactly (11.5%, A/E 0.82). The rider also reads well in Class 5 (16.1%, n=211). The record reads poorly over 1m5f – 2m — 4.7% over 64 rides, 6.2pts below the baseline. 193 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Queen Elizabeth II Jubilee Stakes at Ascot (Jun 2023, £567,100). The standout partner of the record: Boz (GB) — 8 wins from 15 rides together. Seasonally, the rider fires Jan–Mar.

Each tile is the record in that situation vs the 10.9% 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.
