What is Ana O'Brien's strike rate?

Ana O'Brien has won 66 of 782 rides since 2008, a strike rate of 8.4% (as at 6 November 2026). Figures are computed from our own results archive.

Which course does Ana O'Brien do best at?

Limerick by strike rate: 5 wins from 33 rides (15.2%) 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 Ana O'Brien ride most for?

A P O'Brien, with 407 rides since 2008 — 52% of the total. That pairing has won 41 (10.1%).

What is Ana O'Brien's Fair A/E?

0.90, from 781 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.

The read

The record is strongest at Limerick (15.2%, n=33), clear of the rider's 8.4% baseline. It is weakest at Curragh (3.2% over 95 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 12.1% (n=66, Fair A/E 0.85), but in Group and Graded company the record reads poorly at 2.4% (n=42, Fair A/E 0.42). The market has consistently overbet rides in big fields of 14 or more: 4.8% strike, Fair A/E 0.70 and −205.95 to a £1 stake over 315 rides — those runners underperformed what the price implied. A P O'Brien supplied 52% of the rides and matches the rider's average almost exactly (10.1%, A/E 0.93). The rider also read well on Heavy going (18.4%, n=38) and on Good to Firm going (15%, n=133). The record read poorly in Class 1 — 2.4% over 42 rides, 6pts below the baseline. One Group or Graded win sits in the archive record — the biggest prize the rider has landed: the Irish Stallion Farms European Breeders Fund Stanerra Stakes at Leopardstown (IRE) (Jul 2016, £32,450). Seasonally, the rider fired Jun–Jul.

Each tile is the record in that situation vs the 8.4% 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.
