What is M J P O'Brien's strike rate?

M J P O'Brien has won 18 of 225 runners since 2008, a strike rate of 8% (as at 22 October 2026). Figures are computed from our own results archive.

Which course does M J P O'Brien do best at?

Dundalk (AW) by strike rate: 7 wins from 32 runners (21.9%) since 2008. Read from the 15 courses with the most runners 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.

What is M J P O'Brien's Fair A/E?

0.90, from 225 runners 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 Dundalk (AW) (21.9%, n=32), clear of the yard's 8% baseline. The yard also read well on Standard (AW) going (21.9%, n=32) and off a 31-60-day break (14.3%, n=35). The record read poorly over 2m1f – 2m4f — 0% over 41 runners, 8pts below the baseline. 14 Group and Graded wins sit in the archive record — the biggest prize the yard has landed: the Pierse Hurdle at Leopardstown (Jan 2005, £78,650). The stable star of the record was Forget The Past (GB) — 6 wins from 23 runs for the yard.

Each tile is the record in that situation vs the 8% baseline — descriptive splits with the sample always shown, not tips. Tiles under 30 runs render muted. Headgear figures use the true-first definition (first gear appearance in the captured career); returns are gear back on after a bare run. Claiming riders are runs where the booked rider carried a weight claim. Group / Graded covers pattern and listed races.

All 48 horses sent out in this window. 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.

Where they came from · where they went next

Of the 48 horses listed, 11 arrived from another yard in our archive; 37 had their first archived run for this yard.

31 have since run for another yard, most often for Denis W Cullen (14) and F Oakes (2); 17 have no later run for another yard in our archive.

Read from each listed horse's whole archived career (2005 onwards), not only this window, and counted over the horses listed above, not the whole string. “First archived run” means our archive holds nothing earlier, not that the horse was unraced. A horse with no later run elsewhere may still be here, be off the track, or have run somewhere our archive does not cover — none of that is asserted.

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.
