Yes, a captain must register individually and create a team with a user code and password, which he or she will then give to his or her teammates, who will then be able to register by choosing the team they have created. A drop-down menu on the registration page (JOIN A TEAM) will appear. The team time will be the 4 best times of your team added together. It is a team effort to help your best teammates get through the obstacles. You don't have to be on the same starting wave. You can run by helping your teammates or by running individually.
