My friend and I are planning on participating in this event, and
possibly others.

We just have a few questions.

1. Do we need to register in advance, or can we register the day of?
2. Do we choose our class (A,B,C) at first?
3. Is it okay to ride our mountain bikes at first instead of bona-
fide cross bikes?

4. Are we able to go out to the site and ride the course in advance
to get a feel for it and practice a little?

5. Any other newbie things we need to know, like stuff we have to
bring, etc that people often overlook thier first time?

Thanks!
