It’s commonly known that swimming requires a body of water to practice in. Somewhere near you there will be one, hopefully heated and with cheap entry fees and few rules. Your average swimming pool is 25m in length with a deep end and a shallow end, contains chlorine to kill bugs and hair (but not in the CSS way see Ch1) and is rectangular in shape. Outdoor 50m pools are less common and just a challenge to ingrained swimmer maths and cold but require less turns and are pleasantly empty once summer finishes. And yes the ocean is wide and beautiful and free but also dark with shadows imagined or real,lonely and bumpy and generally without hot showers unless it’s mid winter and the cold water you just exited makes the cold shower you’ve just entered seem warm, its relative.
‘The Swimnerds Guide to Moving through Water‘ takes one of its basic ideas from the linear universe and with unashamed simplification fits everyone into the body shape of a rectangle, a square or a triangle.
