KTB Speed and Rating
KTB Speed
No KTB Speed figures for this horse. The engine scores GB and Irish racing from Oct 2016; runs elsewhere, or earlier, have no figure.
KTB Speed v1 · batch 15 Sep 2026 · GB & Irish racing only · 0 figures from 0 runs · a record, not a forecast
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.
