Dermot P O'Brien has been training racehorses for four years, building his yard since 2021. Over the last twelve months, he has sent out seven runners without a winner — a frustrating stretch that any trainer would find difficult. His most notable partnership has been with the horse Annie Hope Harriet, but that pairing has also struggled, combining for seven races with no wins.Based on TrackLab's analysis

TrackLab's trainer breakdown
For a trainer still relatively early in his career, blank runs happen. What matters now is whether O'Brien can get his team firing. Four years in, he has time to turn things around and find the horses and the formula that work.
