Good plan to have bun after swimming - unless you really need to lose weight.
As children, swimming meant a 30 miles round trip to nearest indoor pool in Tewkesbury. Then Mum would concentrate on one child, usually my younger sister, and try to chat up a lifeguard to lend us floats and keep an eye on me. Then, out of pool to walk through market to baker's shop to buy a doughnut each to eat beside River Severn and watch swans and ducks at weir. So, no surprise that we could both swim pretty well before we started school, and still love swimming, water sports, marine biology (last one me only) etc.
