Yuichiro Miura scaled Mount Everest at age 70 and 75, but even he didn't think he could do it now.
When he reached the 29,035-foot peak Thursday morning, the Japanese mountaineer called his Tokyo-based support team with the news.
"I made it!" Miura said over the phone, according to the Associated Press. "I never imagined I could make it to the top of Mt. Everest at age 80. This is the world's best feeling, although I'm totally exhausted. Even at 80, I can still do quite well."
Also a daredevil skier, Miura has had four heart operations since 2007, his daughter told the AP. He fractured his pelvis and left thigh bone in a 2009 skiing accident. On his website, he wrote that he wanted to climb Everest “to challenge (my) own ultimate limit. It is to honor the great Mother Nature,” according to the AP.
"And if the limit of age 80 is at the summit of Mt. Everest, the highest place on earth, one can never be happier."
Miura skied down Everest's South Col in 1970, according to the AP. The feat is the subject of the Oscar-winning 1975 documentary, “The Man Who Skied Down Everest.”
Miura's status as the oldest person to scale Everest could end next week, however, when an 81-year-old Nepalese man, Min Bahadur Sherchan, attempts the feat. Sherchan also did it at age 76.
