Ross Edgley famously ran a marathon pulling a 1.4-tonne car and climbed a rope the height of Everest (8,848m). On his epic 1,780-mile journey around Great Britain, which lasted 157 days, Ross swam through giant jellyfish, arctic storms, ‘haunted’ whirlpools and polluted shipping lanes, going so hard, and so fast, his tongue fell apart. Ross uses his swim experience and other amazing endurance feats, where he managed to overcome seemingly insurmountable pain, hardship and adversity, to study the performance of extreme athletes, military and fitness specialists and psychologists to uncover the secrets of mental fitness and explore the concept of resilience, persistence, valour and a disciplined mindset in overcoming adversity. This ground-breaking book represents a paradigm shift in what we thought the human body and mind were capable of and will give you a blueprint to become a tougher, more resilient and ultimately better human.
