In the next three years, Australian, Allie Pepper has her sights set on climbing 14 of the world's highest mountains without supplementary oxygen.
She has already completed two in the last couple of months.
Allie Pepper says doing a technical mountaineering course in New Zealand over 20 years ago changed the direction of her life and firmed up her addiction to thin air.
She experienced a set back to her guiding business and mountain climbing a couple of years ago.
The debilitating symptoms of early onset menopause had her fearing her career in the mountains could be over, but treatment has her back on track.
