KTB Profile

Llangynin Lass is a filly by Havana Gold out of a Mount Nelson mare who has yet to win from five starts.

Her last run, at Kempton in Nov 2025, was her first for Tony Carroll and she finished 10 of 10 in a Class 6 handicap off an official rating of 57.

KTB Speed and Rating

KTB Speed

Best recent Speed 113 the best of the last 2 graded (A or B) runs · Chepstow, 30 May 2025

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 63A the best of the last 3 rated runs · Chepstow, 30 May 2025 Official rating 57 at the last run, 3 Nov 2025

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.
