where are you? Lincolnshire Police (used to, at least) subsidise track-based road riding instruction. Spent a day at Cadwell Park, half day in classroom half day on track practising various exercises before finishing with half a dozen uninterrupted laps of the full circuit. It absolutely chucked it down (standing water in places) which from a learning perspective was ideal. At that point I’d been riding for ~20 years, year-round, but still had stuff to learn (past tense only because I’ve lost my moto mojo and don’t ride, not because I now know everything….). I heard about it through a mate and rode up from Oxford to do it and stayed in a B+B, well worth the effort.
It was with Hopp Rider Training.
