Registration is going on right now, with prices going up on 1 August. They have divisions for Rx, Scaled, and Masters individuals, as well 2-person team divisions of: MM Rx, FF Rx, MM Scaled, FF Scaled, MM Masters, FF Masters.
Even if you don't participate as an athlete, I highly encourage you to volunteer or just go as a spectator. If you've never been to a CrossFit competition in person, it is an awesome experience. We all know how supportive the CrossFit community is as a whole, and this attitude of camaraderie extends to competitions, as well.
