Mercury Day
Mercury Day is a consistent performer who knows what it takes to win, even if those victories have dried up over the past couple of years. The five-year-old has managed 2 wins and 6 places from 17 races—a win rate of roughly 1 in every 8 starts—and was last in the winner's circle at Newmarket on 29 June 2024, more than two years ago. Trained by
Conrad Allen's Newmarket yard, which has had a productive season sending out 13 winners, Mercury Day remains active and was last racing just a day ago, but has now gone 15 races without breaking through.

🔍 Full Analysis
TrackLab's AI-generated assessment based on career data and recent form
The horse shows real promise over one mile one furlong to one mile two furlongs, distances where it has won 2 of its 6 races (a 33 per cent win rate). That kind of form at those specific distances suggests the horse does have the tactical scope to compete and win when conditions suit. Mercury Day has also proven itself capable at the higher Class 4 level, though with only 1 win from 6 attempts there, it has found that tier challenging. Recent form paints a picture of a hard-trying runner that is still mixing in placings—third place five races back, fifth most recently—but cannot quite find the form to get back in the winner's enclosure. With two victories behind it and clear evidence that it can perform at distance and level, there is still a horse that knows how to race. Finding that winning formula again is now the task ahead.
