The broader numbers are equally hard to ignore. Five wins from nine races is a 56% win rate — more than one in every two races entered ends in victory. That is an extraordinary return at any level of the sport. The recent run of form makes it even more striking: four wins from the last six races, with a second and a third filling the gaps. There has been barely a bad day at the office. Most recently, Tenability won at Goodwood just this week, so this is a horse operating right at the peak of its powers in real time.
One of those wins came at Class 2 level at Ascot in September 2025 — one of the better races in Britain, the kind of event that separates horses who are merely good at their level from those who can compete with the best. Tenability passed that test. The first career win came at Windsor in June 2025, and since then the horse has barely looked back, accumulating wins at a pace that catches the eye even among seasoned followers of the sport.
Behind all of this is William Haggas, one of the most respected trainers in the country, based out of Newmarket in Suffolk. His yard has sent out 170 winners already this season — that is not a lucky streak, that is a training operation firing on all cylinders. Horses from his stable are prepared with care and placed intelligently, and Tenability looks like a prime example of that approach: a horse given the right races, on the right tracks, at the right moments. At just four years old, with a Goodwood win this week and Ascot already conquered, there is every reason to think the best may still be ahead.
