Walker had decided he was going to change his career path and become an endurance athlete (an endurance swimmer) a few years before that. He didn’t want to sell toasters forever and was hoping to accomplish better things than that, so he started a pretty tough training in order to one day reach his goals.
He actually went all the way with his training and schedule, following a pretty strict program and going to his limit. He also studied quite a lot, reading a lot of books and getting ready for the very first challenge he would have to face. But he would never have expected what actually happened. It was a real surprise.
