Should I bet on Pierre Bonnard?

Yes — back him to win if you trust O’Brien’s placement; otherwise take an each-way if the market is short and you want insurance.

What makes Aidan O’Brien dangerous in the St Leger?

O’Brien’s record and skill at targeting classic distance races mean his runners are rarely out of the tactic and placement battle; experience matters here.

Bonnard for the Leger: The Guru Backs O'Brien’s Bid to Make History

Hollie Doyle’s blog headline is not idle theatre — her public backing of Pierre Bonnard to secure a Leger for Aidan O’Brien reframes this race as a test of stamina and old-school judgment. St Leger week always distils a season into a single trip; Doyle’s endorsement adds a layer of inside confidence that punters should not dismiss lightly.

Pierre Bonnard’s profile ticks the essential boxes for the Doncaster classic: route pedigree, a compact turn of foot that can grind, and racecraft sharpened over longer trips. He does not need to frighten the market to be dangerous; what matters is how O’Brien places him and whether the pace setup plays to his strengths.

Doyle’s view carries extra weight because jockeys feel the animal, not just the formbook — when a rider speaks up before a Group 1 they usually see readiness others miss. O’Brien hunting a milestone Leger only intensifies the planning; nine triumphs whisper experience, and experience at this level often decides tight finishes.

The Guru’s call is clear: back Pierre Bonnard to win, or take an each-way ticket if the price is guarded — this is a race where profile and training beat hype. Stake sensibly; if the market underestimates the trip and O’Brien’s placement, Bonnard is the value play. I expect him to be in the frame and to take the race if conditions and pace fall kindly.
