What it means

Class indicates the competitive level of a race. Flat racing commonly uses Classes 1 through 6, with Class 1 the highest.

Race class groups contests by quality or conditions; it is not a direct ranking of every individual runner.

A worked example

A horse moving from a Class 5 race into Class 3 faces a different level of opposition.

A runner dropping from a stronger race can be interesting, but a class drop alone is not evidence of a profitable price.

How to apply this to a racecard

Check the specific race date, course, distance, going, class, carried weight and available runner history. Prefer comparable recent evidence to isolated flags.

Common mistakes and limitations

National Hunt race classification and individual race conditions require separate interpretation.

Past performance can be informative without being predictive on its own; conditions and opposition change from race to race.
