Aye, aaron, it’s an example of the rebranding of Banded races as Classified races, and the dispersing thereof throughout racecards of otherwise higher quality races (rather than having entire cards consisting of nothing but class 7s).
Not that Classified races didn’t exist beforehand, of course – there are plenty of other, better and longer-established Classified contests dotted throughout the calendar. I’m bound to trot out the jumps examples, as it’s my greater area of knowledge, but from memory during the course of the year Ayr, Newcastle, Hexham, Hereford, Newton Abbot, Fontwell, Plumpton and maybe a few others will all host Classified hurdles and chases, typically limited to horses rated 0-90 or 0-95.
The patron saint of lower-grade fare. A gently critical friend of point-to-pointing. Kindness is a political act.
