KTB Profile

Gatsby Blue is a gelding by Blue Bresil out of a Malinas mare and has yet to win from five starts on turf. He has raced once at each of Thurles, Listowel, Carlisle and Ayr, with three runs over 1m5f to 2m, one over 2m1f to 2m4f and one over 2m5f to 3m, all on good or good to soft going. His last run came at Thurles in Oct 2025 in a maiden hurdle when he raced off an official rating of 83, which was his career-high mark, and headgear returned.

KTB Speed and Rating

KTB Speed

Best recent Speed — no A or B graded figure in the last 3 runs; the figures below carry grade C

How fast the horse ran, as points against the day-corrected standard time for its course and distance: 100 is the median GB Class 4 handicap winner on that code; one point is 0.1% of the standard time. A, B or C is how much the day's card could tell us, not how good the run was. What this means →

KTB Rating

Best recent KTB Rating 78C the best of the last 2 rated runs · Ayr, 28 Oct 2024 Official rating 83 at the last run, 16 Oct 2025

What the horse achieved in each race, in pounds on the official-rating scale, from the weight carried, the lengths beaten and the race's own level solved across the archive — never the market, never the official rating as a starting point. The headline is the best of the horse's last three rated runs on that code — its best recent day. The KTB Rating on a racecard is a different reading of the same figures: the level the horse has been running to, an average of up to its last six runs with the latest counting most, so the two can differ. A, B or C on a run is how much known form was in that race. What this means →

Both figures are KTB's own, computed from the archive; no vendor rating enters either. Every run's figure is on its form line below with its grade. Grades measure how much the archive could see, never the merit of the run.
