What is a swim team?
The quick answer is that a swim team is a group of swimmers that train and compete together in swim meets.  But a swim team is more than just swimmers - being on a swim team teaches dedication, support, and mentorship.
Why join a swim team?
Some swimmers find greater motivation and encouragement when training with other swimmers.  A swim team is a way to improve on skills in the water while building friendships with teammates.
Isn't swimming an individual sport?
Yes and no.  While each individual swimmer works hard all season to improve times individually, these improvements come together to help in team relays and overall team scores.
