One adult in five cannot swim, and the classes are not full of children
What the class is like
Six to eight adults, a closed pool, and nobody watching from the side. The shallow end is one point two metres throughout.
How long it takes
Most people are swimming a width within four sessions and a length within about twelve. That is the ordinary rate, not the fast one.
What to wear
Whatever you would wear on a beach. Nobody looks and the whole class is in the water within two minutes of arriving.
