Beyond Endurance by Kilian Jornet, the Catalan professional long-distance trail runner and ski mountaineer widely considered one of the greatest mountain athletes of all time, is a first-person visual and written account of an extraordinary Alpine undertaking. In 2024, Jornet made international headlines by summiting eighty-two peaks over thirteen thousand feet in just nineteen days, smashing the previous record by three days and traversing the Alps at a pace never before achieved.

Set against glaciers and ridgelines undergoing rapid change, Beyond Endurance also serves as a powerful act of witness to the accelerating impact of climate change in the Alpine world. Including more than two hundred full-color illustrations featuring the formidable Alpine peaks and Jornet's journey through them, this book bears witness to the transcendent beauty of the mountain environment. The result is a remarkable, seemingly unimaginable, human feat and a book that has been praised in publications around the world including El País, which says "Jornet captures the ethereal, the human, and the philosophical aspects of [. . .] his Homeric ride between glaciers and peaks, and offers reflections that no measured figure can resolve."
