This is an interesting book on the challenges of open water endurance swimming. Author Ryan Stamrood from South Africa started out at the age of 27 as a typical, not particularly fit adult. He then decided to devote himself seriously to swimming training. His first objective was the Robben Island swim (7.5 km or 4.7 miles) from the coast near Cape Town to the island where Nelson Mandela was a political prisoner for many years. Having accomplished this, he continued to swim increasingly difficult open water challenges, culminating in a successful crossing of the English Channel.
Things really took a serious turn when he realized that he and some friends had a knack for swimming in cold water, and together they formed the International Ice Swimming Association. He went on to do some stunning swims, including in a freezing lake in Siberia and swimming a mile in Antarctica.
He began his career in advertising, working for his father, whose business he eventually took over and continued to grow successfully. But after those years of serious adventures, he pivoted to becoming a motivational speaker.
The book itself was very motivating. I drew a strong conclusion. What you consider your “impossible” now can later become the starting point for building greater things. For example, Ryan started to think that the Robben Island swim was impossible, but now he has to do a double swim to get a good workout workout.
