Our swimmers nurture their swimming abilities while also learning the importance of hard work, teamwork and sportsmanship. Participants are divided into groups based on age, skill performance and endurance. Kids are encouraged to come to every practice and will compete in meets throughout the summer. There will be a league championship meet in the Boulder Valley area at the end of the season. Registration includes t-shirt and swim cap.

All pre-team swimmers must be able to swim 25 meters of freestyle and backstroke unaided. This program does not replace the need for swim lessons. Pre-team does not participate in swim meets. Registration includes swim cap.
