Prerequisites

To join Great Bay Masters, swimmers should be able to:
    • Swim repeat 100s freestyle at a steady pace
    • Comfortably swim 25/50 of at least two other strokes
    • Show willingness to learn additional strokes
    • Follow the lane etiquette and the written workout at an appropriate pace

Registration & Attendance Notes
This program is popular and will sell out! To ensure fairness and space, please choose the option that best matches your schedule. We kindly ask swimmers not to register for full-session passes if they expect to attend only a handful of practices. This helps keep spots open for those committed to the full winter session—and may save you money!

Please Note:
  • Monday passes cannot be used for Wednesday practices, and vice-versa.
  • No “at-desk” registrations are available before practice. All participants must pre-register.
  • If you’re unsure about your schedule, consider other great programs at the Indoor Pool or GBM opportunities in Dover or Exeter.

Season Pass - Every practice
NEW This Session: Lane Registration To improve comfort and safety during practices, swimmers now choose a specific set of lanes when registering. Please select one group for the session: • Lanes 1–2: 50m @ :40–:50 • Lanes 3–4: 50m @ :50–1:00 • Lanes 5–6: 50m @ 1:00–1:15 The workout content remains the same regardless of lane—this system simply helps prevent overcrowding. Thank you for your patience as we fine-tune lane management!
