Becoming the All-Terrain Human

Kilian Jornet Burgada is the most dominating endurance athlete of his generation. In just eight years, Jornet has won more than 80 races, claimed some 16 titles and set at least a dozen speed records, many of them in distances that would require the rest of us to purchase an airplane ticket. He has run across entire landmasses­ (Corsica) and mountain ranges (the Pyrenees), nearly without pause. He regularly runs all day eating only wild berries and drinking only from streams. On summer mornings he will set off from his apartment door at the foot of Mont Blanc and run nearly two and a half vertical miles up to Europe’s roof — over cracked glaciers, past Gore-Tex’d climbers, into the thin air at 15,781 feet — and back home again in less than seven hours, a trip that mountaineers can spend days to complete. A few years ago Jornet ran the 165-mile Tahoe Rim Trail and stopped just twice to sleep on the ground for a total of about 90 minutes. In the middle of the night he took a wrong turn, which added perhaps six miles to his run. He still finished in 38 hours 32 minutes, beating the record of Tim Twietmeyer, a legend in the world of ultrarunning, by more than seven hours. When he reached the finish line, he looked as if he’d just won the local turkey trot.

Come winter, when most elite ultrarunners keep running, Jornet puts away his trail-running shoes for six months and takes up ski-mountaineering racing, which basically amounts to running up and around large mountains on alpine skis. In this sport too, Jornet reigns supreme: he has been the overall World Cup champion three of the last four winters. (...)

Jornet has won dozens of mountain footraces up to 100 miles in length and six world titles in Skyrunning, a series of races of varying distances­ held on billy-goat terrain. “Other Top 5 or 10 ultramarathoners can show up for a race, and he’ll just be jogging along, biding his time, enjoying their company until it’s time to go,” Bryon Powell, the editor in chief of the Web site iRunFar.com, told me. In the longest races, which can last 24 hours, he’s been known to best the competition by an hour or more. Lauri van Houten, executive director of the International Skyrunning Federation, calls Jornet “God on earth.”  (...)

Even among top athletes, Jornet is an outlier. Take his VO2 max, a measure of a person’s ability to consume oxygen and a factor in determining aerobic endurance. An average male’s VO2 max is 45 to 55 ml/kg/min. A college-level 10,000-meter runner’s max is typically 60 to 70. Jornet’s VO2 max is 89.5 — one of the highest recorded, according to Daniel Brotons Cuixart, a sports specialist at the University of Barcelona who tested Jornet last fall. Jornet simply has more men in the engine room, shoveling coal. “I’ve not seen any athletes higher than the low 80s, and we’ve tested some elite athletes,” says Edward Coyle, director of the Human Performance Laboratory at the University of Texas at Austin, who has studied the limits of human exercise performance for three decades.
