Fortunately it is a book that does not rewrite the litany of basic material for beginners (2 glasses for swimming, 2 wheels for a bicycle, running shoes 2 ...) but is for those who have lived (even slight) of the sport. Very good quality concrete analysis: no medical theses on topics such as nutrition, health, the work of muscles. It is a strongly oriented document on the practice of training with a map included (70 pages / 35 weeks) to prepare long triathlons. And that's good. I hope his next book about swimming is also good. Sportingly.
