Do all individual competitors and teams have to be based out of a CrossFit affiliate?
No, you do not have to train at an affiliate to compete as an individual or as a team. The only prerequisites for athletes on an Official Team are: (a) all athletes must train at the same gym and use the same equipment, and (b) the team must have at least three men and three women. An Official Team in the Affiliate Cup could be composed of people from a non-affiliate such as a fire house, neighborhood garage gym collective, etc. Teams wishing to register who are not CrossFit Affiliates must contact games@crossfit.com to be manually entered. Alternatively, anyone can form an Other Team and compete in the Open, but these teams are not eligible for Regional competition. See “Complete Team Rules” for the full details.
