KTB Speed and Rating

KTB Speed

Best recent Speed 84 the best of the last 3 graded (A or B) runs · Wexford, 10 Apr 2026

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 (jumps) 122A the best of the last 3 rated runs · Wexford, 10 Apr 2026 Official rating 94 at the last jumps run, 4 Nov 2026

Best recent KTB Rating (flat) 53A the best of the last 1 rated run · Navan, 22 Jan 2022

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.

The forward record. KTB’s figures on this horse since 4 Nov 2026: top-rated on KTB Rating in 1 run (won 0) · to 4 Nov 2026. Each pick was the figure’s choice before the off, settled against the result the next morning; “did not run” is counted apart. GB and Irish races since 5 Oct 2026.
