Captain Wierzba (GB)
Captain Wierzba won one of eight starts, the success coming in a Class 5 novice at Ffos Las over 6f-7f on good ground in Aug 2022. The gelding, by Night Of Thunder out of a Zamindar mare, has not won since. He raced seven times on turf and once on all-weather. Aged 4 at his last run in May 2024, he finished eighth of eight in a Class 2 handicap at Goodwood off an official rating of 90, 12lb below his highest ever mark.

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 84
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.
