His preferred distance also matters. Over middle distances from a mile and six furlongs to two miles, he has won seven of eighteen races, nearly 39%, compared to a much weaker return elsewhere. Pair Wolverhampton with normal ground conditions and you have a horse worth paying attention to. He has won seven races from nineteen on standard conditions, a 37% win rate that stands well above his overall average. The artificial surface at Wolverhampton plays into this — it is consistent, predictable, and suits his running style.
Billy Loughnane, the trainer's son, has partnered with Haku for nine races and won four of them, a 44% win rate that suggests genuine understanding between horse and jockey. Their last success came in a Class 2 race at Southwell on 28 November 2025, a significant win that showed Haku could still compete at a decent level. His recent form has been mixed — a win, then places, then further back finishes — typical of a seven-year-old finding the going tougher as his career progresses. But at Wolverhampton, on normal ground, over his preferred distance, and with Loughnane in the saddle, Haku remains a horse to respect.
