Thundering On

The win came at Navan on 25 April 2026, and it capped a sequence of form — fourth, second, second, then first — that tells a clear story: a young horse finding its feet, improving with every run, and finally getting its head in front at the right moment. The trainer Joseph Patrick O'Brien had already flagged her as one to watch, noting her strong pedigree and describing her as exciting. He had also pointed out that her previous run, where she finished second, came in a highly competitive race against a filly he rated as top class — so that placed effort was worth considerably more than it might look on paper.

O'Brien, based at Owning Hill in Co Kilkenny, is having a serious season — 154 winners sent out so far, which is the kind of output that marks out a yard operating at the very top of its game. Horses from that stable tend to be well placed and well prepared, and the plan for Thundering On is to step her up into stakes company, the higher-tier races where the best horses in her age group compete. Exactly where and when is still to be decided, but the fact that she is being aimed there at all says something about the expectations around her.

Four races is a small sample, but everything in those four races points the same way. A horse that finishes second to a high-class rival, then wins at her next opportunity, trained by one of the most prolific yards in Ireland and earmarked for better company — that is a profile worth paying attention to.
