Siempre Arturo

There is a horse in the Kubler yard at Lambourn who has quietly become one of the more reliable performers at his level — and at six years old, he may still be getting better. Siempre Arturo has won 8 of his 24 races, a win rate of 33%, or roughly 1 in every 3, which is a genuinely impressive number for a horse who races as often as he does. Eight career wins is not the total of a horse finding his feet — it is the record of a horse who knows how to win.Based on TrackLab's analysis

TrackLab's detailed breakdown

His best form comes at Kempton Park, where he has won 2 of his 6 visits. That might not sound dramatic, but Kempton is a tight, artificial track that suits specific types, and the fact that Siempre Arturo keeps going back and keeps performing tells you something about how well he travels around it. His most recent win came there in September 2025. The trainer, Daniel Kubler, has been candid that he felt the horse was unlucky on a recent return to the same track — not beaten on merit, but caught out by how the race unfolded. Crucially, Kubler noted his horse still posted a fast finishing time that day. In other words, the engine was running, the race just didn't suit him.

What makes this horse worth watching is where the team believe he is heading. Kubler has mentioned the John Smith's Cup — a competitive, big-field flat race — as a potential target, and the thinking is that a wide, galloping track could really bring the best out of him. He has progressed and matured with racing rather than peaking early, which is an encouraging sign. At Class 5, the level at which he most often competes, he has won 4 of 7 races — that is 57%, or more than 1 in every 2 — a dominant record that suggests he is well above the standard at that grade on his day.

Jim Crowley, one of the sharper jockeys in British flat racing, has been on board for 6 of his races and won 2 of them, a 33% win rate that matches the horse's overall average almost exactly. The yard itself has been in strong form, sending out 34 winners this season. Siempre Arturo raced just yesterday, so he is clearly in active training — and if the Kubler team are right about where this horse is going, his best days may not yet be behind him.
