“The most dominating endurance athlete of his generation.” — New York Times

An exceptional athlete. A dominating force. An extraordinary person.

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.

Jornet adores the mountains with the same ferocity with which he runs them. In Run or Die he shares his passion, inviting readers into a fascinating world rich with the beauty of rugged trails and mountain vistas, the pulse-pounding drama of racing, and an intense love for sport and the landscapes that surround him.

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.

 Praise for this book

The most dominating endurance athlete of his generation.

New York Times

Rarely has a top-of-the-world athlete offered such candor, honesty and wisdom while still in his or her prime as Kilian Jornet does in Run or Die…His time in the mountains has made him a wise old soul and a great storyteller…An intriguing read.

Competitor magazine

Kilian Jornet is poised to be trail running’s first true breakout star, an ever-smiling, seemingly tireless 23-year-old Spaniard who’s yet to find a record he can’t shatter.

Runner’s World magazine

Kilian Jornet is the world’s best.


Jornet unspools a dream-like narrative of his thoughts on running in present-tense storytelling that brings the reader along on such romps as an eight-day crossing of the Pyrenees, a 165-km passage of the Tahoe Rim Trail, and a couple of record-breaking mountain climbs…Readers hungering to find meaning in their own running experiences will find poetry to savor here.

Canadian Running magazine

We are brought into the heart and soul of who many consider the fastest ultrarunner to hit this planet. The story is raw. It is rough, and it is emotional. [The casual runner] may not feel the pain, the anguish, the push and pull of the emotions, but I can guarantee the mountaineer, adventurer, ultrarunner, or long distance athlete who ponders what sport and adventure truly mean to them will appreciate and take in what it means to be Kilian Jornet.


An engaging read…Kilian is…the best mountain runner of any distance from one vertical kilometer to 100 miles, having won most every big race and set fastest known times on the biggest of peaks around the world.
