Like most people –– breast stroke is my strongest stroke. But I’ve joined the flipper-wearing fast laners recently, and so I’m doing a lot more crawl. I’m tempted to take a lesson or two to improve my stroke. When it’s something you’ve done all your life, it feels strange to take a lesson in it. One woman I swim with, moves with such strength, grace and fluidity up and down the pool that she makes her 50-odd laps of crawl look like a cinch. Maybe, I’ll ask her for a few tips. Take a look at this series of images by Maria Svarbova. They’re so striking and crisp. Don’t they make you want to dive right in?
