Nepal’s government honored record-holding climbers Monday during celebrations of the first ascent of Mount Everest 70 years ago.
The celebrations come amid a growing concern about temperatures rising, glaciers and snow melting, and weather being harsh and unpredictable on the world’s tallest mountain.
Hundreds of people from the mountaineering community, Sherpa guides and officials attended a rally in Kathmandu to mark the anniversary. Participants waved celebratory banners and walked in the center of Kathmandu to tunes played by military bands.
Among those honored were Sherpa guides Kami Rita, who climbed Everest twice this season for a record 28 times overall, and Sanu Sherpa, who has climbed all of the world’s 14 highest peaks twice.
In the spring and summer, he trained two to four hours a day, six days a week, running daily and carrying 60 pounds of water up a 4,000-foot peak near his home in Seattle twice a week. “All the research has shown that 80 percent of training for alpine ascents needs to be long duration and low intensity, to build a huge foundation of endurance,” Swenson says. “There are no shortcuts to this. There’s no thirty-minute-a-day gym workout. You have to have the discipline to put the time in.”
