Emperor Zen (IRE)
Emperor Zen won once from 10 starts, the success coming in a Class 5 handicap at Kempton over 1m to 1m1f on standard going in Dec 2022. The gelding, by Holy Roman Emperor out of a daughter of Iffraaj, placed five times overall and showed his best form on all-weather surfaces. He last ran at Windsor in Jun 2023 when finishing second of three in a Class 5 handicap off a mark of 73.

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 79
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.
