I'm not a very good swimmer. Only their swim times. C and D swim on alternate mornings, with additional optional swims available. See the current schedule for details.
All groups have swimmers with a wide range of swimming abilities and ages.
A larger portion of the competitive swimmers are in group A, only because competitive swimmers usually like to get as much pool time as possible. We strongly advise everyone to see their doctor prior to starting a swim program, but cannot require a medical certificate. We will require you to sign a waiver as part of the registration process. Again, you should see your doctor. We have had several members continue to swim right through their pregnancies and they all report that swimming did help them.
