KTB Speed and Rating
Best recent Speed 75
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 →

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.
Run style is derived from in-running commentary, which our data provider does not supply for this horse's races.
