Dark Side Thunder

The seven-year-old has built a solid career across 47 races, winning 9 of them and finishing in the places a further 20 times, meaning it has given its supporters something to cheer in more than 6 out of every 10 races it has entered. That overall record of 9 wins from 47 races — roughly 1 in every 5 — tells the story of a consistent, reliable performer at Class 5 level, which is the everyday bread-and-butter tier of British racing. At that level specifically, Dark Side Thunder wins 6 from 22, or just over 1 in 4, which is genuinely impressive.

The horse has also become something of a specialist at Kempton Park, winning 3 of its 5 races there. Three wins from five visits at a specific track is the kind of record that makes trainers smile — it suggests the horse simply suits the circuit, probably its flat, right-handed layout. Jessica Macey's yard in Doncaster has had a productive season with 13 winners already, and Dark Side Thunder is a reliable contributor to that tally.

The partnership with jockey Lewis Edmunds is one of the most interesting threads in this horse's story. In 34 races together, they have won 8 times — a win rate of roughly 1 in every 4 — which is meaningfully better than the horse's overall average. That kind of consistent improvement with one rider usually means they have developed a real understanding. Edmunds clearly knows how to get the best from this horse.

The last win came at Chelmsford in December 2025, and the most recent six runs have produced a second place but no wins. Racing just yesterday, Dark Side Thunder is very much active and still competitive — a second place in those recent outings suggests the spark is still there. With summer fading and wetter weather on the horizon, the horse that wins half its races on soft ground may be about to become very interesting again.
