KTB Profile

Assailant won two of six starts. Both wins came on a first visit to the course, at Goodwood in a Class 3 handicap over 1m2f – 1m4f on good to firm in Aug 2024 and at Wolverhampton over 1m – 1m1f on standard in Dec 2023. The gelding, by Dubawi out of a King’s Best mare, was held up when taking the Goodwood race last time out off an official rating of 83, which was also his career-high mark.

KTB Speed and Rating

KTB Speed

Best recent Speed 70 the best of the last 3 graded (A or B) runs · Wolverhampton (AW), 9 Dec 2023

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 87A the best of the last 3 rated runs · Goodwood, 2 Aug 2024 Official rating 83 at the last run, 2 Aug 2024

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 →

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.
