Yes, of course! We love when Members join more than one team. :)
You might be wondering, well, how will my miles save to multiple teams? Your miles will distribute on each team you're a part of evenly. Note, this doesn't change how much money is earned for charity. However, it allows you to engage a variety of different communities you may want to be a part of.
For example, you can be on a variety of teams for your running club, family, college friends and work colleagues.
