UK mountaineer Valerie Parkinson has climbed Manaslu without using oxygen. Valerie was part of the Altitude Junkies Manaslu Expedition, and was climbing with Phil Crampton and Tarki Sherpa of Nepal.
"I have done trekking peaks up to 6400m before... I am not a climber and Manaslu was my first 8000m peak. I was with Phil Crampton and his company Altitude Junkies. Phil taught me how to climb on the mountain."
