A 13-year-old boy from California, the United States, is set to make an attempt on the world's tallest peak, Mt. Qomolangma, local media reported on Saturday.

Jordan Romero, who is embarking on the Qomolangma expedition on Sunday, will be the youngest mountaineer to scale the peak, if he is successful in his attempt.

"I am hoping to change that by doing what I do -- climbing and motivational speaking. I want to motivate children and inspire them to get outdoors," nepalnews.com quoted the boy as saying. "I am doing this a little for myself too, to do something big," he further said.

"I have been exercising hard, concentrating on cardio training and endurance training," Jordan said, "I have been sleeping in an altitude simulator tent for the past month to get my lungs ready."
