As someone newer to racing, I was curious who here living in Colorado were planning on racing the Louisville or Groove-Subaru crits?

I am planning on racing both, but was curious if others racing or have raced in the past could tell me:

A) What is each course like?
B) Which is more difficult?
C) What are some keys on each course?
D) Do early breaks usually get rounded up, or is it essentially respond to each attack because if you lose it, you are not getting it back?

Thanks,
