KTB Profile

Dr Hackenbush is a colt by Ulysses out of a Green Desert mare who was yet to win from four starts. He raced twice on turf and twice on all-weather without placing, contesting races over 1m to 1m4f on ground ranging from good to firm to soft and standard. His last run, at Wolverhampton in Nov 2023, was his first in first-time headgear when he finished fifth of nine in a Class 5 nursery off an official rating of 70, which was also his highest ever mark.

KTB Speed and Rating

KTB Speed

Best recent Speed 89 the best of the last 2 graded (A or B) runs · Chelmsford City (AW), 11 Nov 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 71A the best of the last 3 rated runs · Chelmsford City (AW), 11 Nov 2023 Official rating 70 at the last run, 23 Nov 2023

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.

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