Kilian Jornet has conquered some of the toughest physical tests on the planet. He has run up and down Mt. Kilimanjaro faster than any other human being, and struck down world records in every challenge that has been proposed, all before the age of 25. Redefining what is possible, Jornet continually pushes the limits of human ability, astonishing competitors with his near-superhuman fitness and ability.
In turns inspiring, insightful, candid, and deeply personal, this is a book written from the heart of the world’s greatest endurance runner, for whom life presents one simple choice: Run. Or die.
