Sounds great man, I also just had my first MB race.
I competed in beginner so 3 laps as oposed to sport (5) and expert (7).
My beat to **** 10 year old bike and I had an amazing time. I thought I was going to die durring the first lap but fell into stride durring the last two and almost wished I had done more. There another series this august which I am definatley doing. Can't wait.
