As a coaching staff, we strive to provide guidance, instruction, and motivation for our swimmers. You are encouraged to talk to your on-deck coach about your personal goals with training in the pool. Please fill out this swimmer goal sheet and bring it to your regular coach to help facilitate that discussion. Read our training plan document to understand how our workouts help fitness swimmers, competitive swimmers, and triathletes/open water swimmers.
