In a week, or so, you'll find out how this is very different from an internal training program. We're going to make this very external, a learning experience for whoever wants to be involved.
My goal, at the time i started my company, was to build a really hard-core team. I am sure that is one of your goals too, aside from providing a really intensive training program for your participants.
I would suggest focusing on good habits and good attitude to learning and problem-solving and having fun in the process. Don't allow them to burn out short-term.
