The key is Thirsk. At that North Yorkshire track, Miss Rainbow has won 2 of her 4 races, which is the kind of record that makes a trainer think twice before sending her anywhere else. Her most recent win came there on 25 July 2025, and her first career win was also at Thirsk, back on 6 June 2025 — two wins from the same venue within seven weeks tells you she belongs there. She is trained by Tracy Waggott at Spennymoor in County Durham, a yard that has sent out 10 winners already this season, and the journey down the A19 to Thirsk clearly suits her.
What also suits her is the ground. On normal conditions she has won 3 of her 10 races — a 30% win rate, or roughly 1 in every 3 starts. That is a striking number for a horse whose overall record is considerably more modest. Her trainer has been candid about this: she actually wants really soft, wet ground, and has barely seen those conditions since a promising run at Catterick early in her career. Getting the right surface has been the puzzle, and when Thirsk came up recently but the conditions were not right, the yard held her back rather than waste a run. That kind of patience suggests they know exactly what they have.
Her most trusted partner in the saddle is William Pyle, who has ridden her in 18 of her 34 races and won 3 of them — a 17% win rate together, which is meaningfully better than her overall average. She races most often at the lowest level of competition, Class 6, where she has won 3 of 22 races. That is the bread-and-butter level of British racing, which keeps her busy and competitive without overfacing her. She raced just yesterday, finishing second and third in her last two runs, so the form is clearly there. When the ground softens and Thirsk comes around again, Miss Rainbow will be well worth watching.
