Nima Rinji Sherpa, 18, climbed the world's eighth-highest mountain shortly after his high school exams

Nima Rinji Sherpa, 18, stood atop Tibet’s Mount Shishapangma at about 06:05 local time on Wednesday.

In doing so, he became the latest of just a few dozen people to have scaled all of the world’s “eight-thousanders” - the 14 mountains that the International Mountaineering and Climbing Federation (UIAA) recognises as more than 8,000 metres above sea level.

Sherpa, who started climbing high-altitude mountains at the age of 16, summited all eight-thousanders in 740 days.

He reached the peak of Nepal’s Manaslu, the world's eighth-highest mountain, on 30 September, 2022 - shortly after finishing his 10th-grade high school exams.

On each trek the young athlete was accompanied by his climbing partner, Pasang Nurbu Sherpa.

The record-shattering ascent on Wednesday marked the latest in a long list of accolades for Nima Rinji, who is also the world's youngest climber to have scaled Himalayan mountains G1 and G2; the youngest climber to have scaled Kashmir’s Nanga Parbat; and the youngest climber to have scaled both Mount Everest and nearby Lhotse within 10 hours.

Standing atop Mount Shishapangma on Wednesday morning, though, another life ambition was front of mind for the 18-year-old: to subvert the stereotype of Sherpas as mere helpers who assist foreign climbers on their ascents.

"This summit is not just the culmination of my personal journey, but a tribute to every Sherpa who has ever dared to dream beyond the traditional boundaries set for us," Nima Rinji said shortly after scaling Mount Shishapangma.

"Mountaineering is more than labour, it is a testament to our strength, resilience and passion."
