KTB Speed and Rating

KTB Speed

Best recent Speed 124 the best of the last 3 graded (A or B) runs · Uttoxeter, 28 Jul 2024

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) 118A the best of the last 3 rated runs · Uttoxeter, 28 Jul 2024 Official rating 122 at the last jumps run, 26 Sep 2024

Best recent KTB Rating (flat) 43C the best of the last 1 rated run · Newcastle (AW), 28 Feb 2020

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 →
