Zilfee won both her starts at Class 5 level in 2024 and 2025. She took a maiden at Kempton on standard AW in June 2024 and followed up at Ffos Las on good ground over 1m2f-1m4f in July 2025. Each win came on a first visit to the course. The filly, aged 4 at her last run in Sep 2025, finished 7 of 11 in the Group 2 Park Hill at Doncaster on good to soft.

KTB Speed and Rating

KTB Speed

Best recent Speed 117 the best of the last 2 graded (A or B) runs · Doncaster, 11 Sep 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.

KTB Rating

Best recent KTB Rating 86A the best of the last 3 rated runs · Doncaster, 11 Sep 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. A, B or C on a run is how much known form was in that race.

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.
