Jain Kim is an experienced climber.
In 2006, she became the first woman from Korea to climb all five 8,000 meters (24,064 ft) peaks in the Swiss alpine ski run Alps in 24 hours. In 2009, she made history again by setting the record for the fastest time to climb an 8,000 meter peak with a team from China and South Korea.
She made the first ascent of 8,832-meter K2 in China, the second highest mountain in the world, in 2009 and the third highest mountain in Europe. She also is the first female Korean to summit a world-class peak.
During her two years as a mountaineering professor at Sogang University in Korea, she established two new routes in the Yalu River area. The first of these routes is a 3,547-meter peak named K2 on Mount Long in China. Her second route is on the same mountain, called the Lomonosov Ridge, at 3,632 meters.
