From doggy paddle to 2,000m in a week? It’s true. An amazing week on the last crash course. The Sawyer sisters started the week as beginners, only able to doggy paddle. Working their way through the breathing technique and the strokes, they learned that swimming is easy- if you stay flat and breathe out in the water. To prove it, on the final day Olivia swam 100m using basic front crawl and backstroke, Isabelle swam an amazing 2,000m. Thats 80 lengths. Wow! Fast learners and the weeks star swimming sisters!
