KTB Speed and Rating

KTB Speed

Best recent Speed 128 the best of the last 3 graded (A or B) runs · Sandown, 29 Aug 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 93A the best of the last 3 rated runs · Sandown, 29 Aug 2026 Official rating 89 at the last run, 19 Sep 2026

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. A, B or C on a run is how much known form was in that race. What this means →
