Jane Du Berlais (GB)
Jane Du Berlais won her only race from ten starts in the Class 4 Sky Sports Racing HD Virgin 535 Mares Novices Hurdle at Lingfield in Dec 2022 over 1m5f to 2m on good to soft. All three turf runs on good to soft produced her win and both placed efforts while she failed to win in five starts on soft. The mare last ran at Taunton in Mar 2024 in a Class 5 mares handicap chase off an official rating of 100 which was 11 lb below her 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 118
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.
