Ross Bentley is doing a virtual track walk for VIR on April 12th. I went to his one on Sebring, and I am going to Sebring this weekend so I can report back on whether I get any faster
I don't know if I will ever make it to VIR (plus it looks scary fast) but if you do this might be a good resource for you:
