Jornet is widely considered the world’s fastest mountain runner and one of the most exciting endurance athletes today. Stephen Kurczy documents one of his recent climbs:
At 6 A.M., he started running from the park entrance. He covered the first fourteen miles to base camp in three and a quarter hours. The next four and a half miles to the summit took five and a quarter hours, during which he climbed nearly nine thousand feet in elevation and the terrain changed from sandy and rocky to snow-covered and icy. The altitude made him disoriented, and wobbly legs and a loss of balance caused him to fall repeatedly, he later told me.
