Dark Side Thunder

There's a horse in Jessica Macey's Doncaster yard that has quietly built one of the more impressive course records you'll find at this level. Dark Side Thunder, a seven-year-old with nine career wins from 50 races — that's roughly 1 in every 5 or 6 outings — has become something of a nightmare for rivals at Kempton Park, winning 3 of just 5 races there. That kind of record at a specific track isn't luck; it's a horse that genuinely suits the place, whether that's the shape of the circuit, the surface, or simply the atmosphere.Based on TrackLab's AI analysis

What makes Dark Side Thunder particularly interesting is what happens when the weather turns. On wet or muddy ground, this horse transforms: 4 wins from 8 races, meaning it wins exactly half the time conditions get soft. At the level it competes — mostly Class 5, which is bread-and-butter racing rather than the glamour end of the sport — a 50% win rate on wet ground is the kind of number that would make any trainer's eyes light up. For context, winning 27% of Class 5 races overall (6 from 22) is already a solid return, but the wet-ground figure is genuinely exceptional.

The partnership with jockey Lewis Edmunds has been central to the horse's success. Together they've won 8 of 35 races — around 1 in every 4 — which is meaningfully better than Dark Side Thunder's overall record and suggests Edmunds has learned exactly how to get the best out of this horse. Macey's yard is in decent form more broadly, having sent out 13 winners already this season.

The honest part of the picture is that Dark Side Thunder hasn't won in its last six races, with recent finishes of 2nd, 9th, 5th, 3rd, 8th, and 2nd — plenty of placed efforts in there, but no visit to the winner's enclosure since Chelmsford in December 2025, now seven months ago. Still, the horse raced just yesterday, so it's clearly fit, active, and still finding its way into the frame. Keep an eye on the forecast. If the ground comes up soft and the track is Kempton, Dark Side Thunder becomes one of the first names you'd want on your radar.
