I suggest contacting SVRA for clarification. A few years ago I asked about registering for 'only' the Collier Cup (the traditional MG only race). The Collier-only fee was just that: one race. (I had hoped I would be able to run in the appropriate practice & qualifying sessions but, no, the entry fee for the Collier Cup was for only that one ~30 minute race.)My assumption is you only need to pay the “sprint race “Alfa” fee. $295.
Anyway, we'll be there this year - but with our MGA. Please come say hello!
