Mercurius Power

The most striking number in its record is this: 1 win from 20 races at Class 5 level, which is the entry-level tier of British racing. That's a 5% win rate — roughly 1 in 20 — which tells you that even at the sport's least demanding level, Mercurius Power finds winners hard to come by. Its last victory came at Southwell on 30 August 2024, which is now 21 months ago, and recent form reads 8-7-6-6-3-3 — a sequence that shows some improvement at the back end but no real sign of a win coming soon.

Jessica Macey trains the horse from her yard in Doncaster, South Yorkshire, and her team has had a productive season, sending out 13 winners. Mercurius Power has not been among them. Lewis Edmunds is the jockey most associated with the horse, riding it 18 times and winning twice together — a win rate of around 11%, or just over 1 in every 9 rides, which is actually a touch better than the horse's overall record and suggests a decent working partnership, even if results have dried up.

The first career win came at Sandown Park back in July 2022, which feels like a long time ago now. What keeps the profile interesting is simply the volume of racing this horse has done — 55 races is a substantial career, and the fact it raced as recently as yesterday suggests it remains fit, willing, and still being aimed at targets. Whether another win is coming is hard to say, but Mercurius Power is the kind of honest, durable horse that makes up the backbone of everyday British racing.
