Dark Island (GB)
Dark Island won once from 14 starts, the success coming in a Class 5 handicap at Kempton over 1m2f – 1m4f on Standard going in Sep 2022. All four places also came on the all-weather, where he ran nine times in total. He finished 5 of 10 at Newcastle in Sep 2023 off an official rating of 75, his last run. The gelding, by Night Of Thunder out of a High Chaparral mare, raced on turf without success.

A/E compares actual wins with what starting prices implied. "Fair" strips the bookmaker margin from the expectation, so favourites and longshots are judged on the same footing — figures near 1.00 mean the market priced this horse about right.
KTB Speed and Rating
Best recent Speed 119
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 →

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.
