Khanacross Highclere - North West Car Club

I don't have the original event description to rewrite. You've only provided the rules and a single sentence ("See the supplementary regulations for further details") which appears to be a closing line rather than the full event details. Could you please share the complete original description for "Khanacross Highclere - North West Car Club"? I'll need the dates, times, prices, venue details, and event activities in order to rewrite it properly.
