Good morning. I'm Renee Montagne. Five years ago, at the age of 75, a Japanese mountaineer raced a 76-year-old Nepalese climber to the top of Mount Everest. Japan's Yuichiro Miura lost. This morning, in an epic rematch, the now 80-year-old Miura won, becoming the oldest person ever to reach the summit. But that record may not last. Next week, his Nepalese rival, at 81, plans to make the ascent again. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
