KTB Profile

Jubilee Girl won once from 12 starts, the success coming in a Class 5 handicap at Southwell over 1m2f – 1m4f on Standard going in Jan 2023. She has not won since. The mare, by Nathaniel out of a Daylami mare, raced six times on turf without success and six times on all-weather with that one win. Her last run, at Stratford in May 2025, saw her finish sixth of eight in a Class 4 novices hurdle after being held.

KTB Speed and Rating

KTB Speed

Best recent Speed 105 the best of the last 3 graded (A or B) runs · Southwell (AW), 7 Mar 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 (flat) 81A the best of the last 3 rated runs · Southwell (AW), 7 Mar 2023 Official rating 71 at the last flat run, 31 Mar 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 — 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 →

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.
