2.5 day event, and it is very good. I did it 2 years ago, had a blast, and learned a ton. It starts out Friday night with a classroom session, then you go back and forth between track and classroom all day Saturday and Sunday. As a semi-newbie, you will be given an instructor for the day Saturday. You then may or may not be signed off for solo on Sunday. Even if you are signed off for solo, you can request an instructor for day 2 as well.
