Janey Mackers

There's something quietly compelling about a horse that wins on debut at one of Britain's most respected tracks, then goes on to land a top-level race at the very same venue. Janey Mackers did exactly that — her first career win came at Doncaster in October 2024, in a Class 2 race that her trainer David Menuisier described as "really eyecatching." That's not throwaway praise from a man who had previously used the same race to introduce Wonderful Tonight, a horse that went on to far bigger things.Based on TrackLab's AI analysis

At four years old, Janey Mackers has raced eight times, winning 2 and finishing in the placings on four other occasions — a record that translates to winning roughly 1 in every 4 races she enters, which is a solid return at this level. Her recent run of form reads 3-12-1-17-6-6 going back from her most recent outing, with that "1" representing her second career win at Newbury in September 2025. The 17th-place finish stands out as an outlier, and it's worth noting that her three attempts at the very top level — Class 1 races — haven't yielded a win yet. That's not unusual; Class 1 is where the very best compete, and getting placed at that level is no small thing.

What makes this horse genuinely interesting is what her trainer believes lies ahead. After Doncaster, Menuisier was already talking about entries in the Oaks and the Prix de Diane — two of the most prestigious middle-distance races for fillies in Europe. That's not something trainers do lightly, and it tells you exactly how the yard rates her. He's also had considerable success with horses by sire New Bay, which adds another layer of quiet confidence to the picture. By the summer of 2025 he was pointing her at a race he'd won before at Goodwood, with the straightforward assessment that there was "more to come" from her this season.

David Menuisier's yard in Pulborough, West Sussex, has sent out 20 winners this season, so this isn't a trainer clutching at straws — he knows what a good horse feels like. Janey Mackers raced just one day ago and remains very much in active campaigning. Whether she can bridge the gap to the very top races remains the question, but the team around her clearly believe the answer is yes.
