From running in the shoe-melting heat of Death Valley to the lung-freezing cold of the South Pole, Dean Karnazes has pushed his body and soul to unimaginable limits. He has raced and competed worldwide and once ran 50 marathons in 50 days across all 50 states.
In A Runner's High, Karnazes chronicles his return to the Western States in his mid-fifties after first completing the race a decade earlier, taking on the 100-Mile Endurance Run. The Western States, famed for its challenging terrain and extreme temperatures, becomes the toughest competition of his life, a physical and emotional reckoning, and a battle to stay true to one's purpose. Confronting his age, his battered body, his career path, and his life choices, we see Karnazes as we never have before. A Runner's High is both an endorphin-fueled page-turner and a love letter to the sport from one of its most celebrated ambassadors.
