On 23rd December Spanish mountain runner Kilian Jornet set a remarkable record for climbing and descending 22,841-foot Aconcagua in Argentina. Kilian ran up and down the Normal Route, beginning at the peak's Horcones trailhead on the south side, in 12 hours 49 minutes.
The route ascends 13,327 vertical feet in about 25 miles to reach the summit. Starting at about 6 a.m., Jornet ran 15 miles to the Plaza de Mules base camp at 14,108 feet (normally a two-day approach from the trailhead), and then started the much steeper ascent of the mountain. He reached the summit about 9 hours later—slower than desired—and made up some time on the descent, completing it in under 4 hours.
A time faster than 13 hours 46 minutes had never before been reported for this route.
Kilian also holds the records for running up and down Denali, Mont Blanc and the Matterhorn. In 2015 he plans to attempt speed ascents of Mt. Everest and Mt. Elbrus, the high points of Asia and Europe.
