Thunderstorm Katie

The horse is trained by Jim Goldie at his yard in Uplawmoor, Lanarkshire, and that context matters. Goldie's operation has sent out 88 winners this season alone, which is a serious number — this is a busy, productive yard that knows how to get horses ready to perform. Most of Thunderstorm Katie's racing has come at the level where she is genuinely competitive: Class 6, the entry-level tier of British racing, and that is where all five of her wins have come. In those races specifically, she has won 5 from 20 — one in every four — which is a markedly better ratio than her overall record and shows she is at home when the competition suits her.

Ground conditions appear to make a real difference. On normal ground — not too wet, not too dry — she has won 3 of her 10 races on that surface, or roughly 1 in 3. That is her sweet spot, and it is the kind of stat a trainer watches closely when deciding when to run.

Her regular partner in the saddle is jockey Amie Waugh, who has ridden her in 12 of her races and partnered her to 2 wins, winning at a rate of about 1 in 6 together. That is a partnership with meaningful experience behind it. The last win the pair can point to came at Newcastle on 27 October 2025 — nine months ago now — which means there is a victory in this horse worth chasing again. Her very first win came at Ayr back in July 2025, which is where the story really started.

She raced just yesterday and remains in active training, which suggests Goldie sees more to come. Three placed finishes in her last six runs on a horse that tends to fire on normal ground is not a horse in trouble — it is a horse waiting for things to click.
