This man just climbed the 72 highest mountains in the U.S. in 31 days

KEY POINTS

Kilian Jornet climbed all 72 of the highest mountains in the continental U.S. in a month.

In 31 days, he traveled nearly 4,000 miles and climbed the equivalent of 14 Mt. Everests.

Jornet started at Long's Peak in Colorado and ended at Mt. Rainier in Washington.

This past weekend, a Spanish endurance athlete Kilian Jornet finished a 31-day effort to climb all 72 of the 14,000-foot high peaks in the continental United States.

Not only did he manage such an awe-inspiring feat, Jornet, 37, did so without the use of planes, trains or automobiles. He used only his “human power” to cover the vast western landscapes between each of the mountains in Colorado, California and Washington.
