So Must I

That sole win arrived at Dundalk on 20 February 2026, and the distance tells an interesting story. So Must I has raced three times at a mile and three to a mile and four furlongs, winning once from those three attempts — a 33% win rate at those trips, or roughly 1 in every 3 races. Compare that to the blanks at other distances and it becomes pretty clear where this horse is most comfortable. Getting a thorough test of stamina seems to bring out the best in it, and the yard will almost certainly lean into that going forward.

The trainer is Joseph Patrick O'Brien, operating out of Owning Hill in Co Kilkenny — one of the most respected yards in Irish racing. The numbers back that up: 160 winners sent out already this season alone. That is the kind of operation where horses are placed carefully and given time to develop, and So Must I, having raced just six times at three years old, is still relatively lightly raced with presumably more improvement to come. Racing just one day ago, this is a horse very much in the middle of its season, and with the right trip and conditions, another win looks well within reach.
