The 14 Peaks Project

I’m climbing to the true summits of all fourteen of the world’s 8000-metre peaks without supplemental oxygen. This is a long-term commitment, built one expedition at a time.

This project is about more than summits. It is a test of endurance, decision-making, self-leadership, and what becomes possible when we commit fully to a vision that feels bigger than us.

Each expedition is a step deeper into uncertainty, responsibility, and trust in experience, preparation and mindset.

Partner with me in 2027

I’m inviting partners to be part of my 2027 expeditions as I work towards climbing all fourteen of the world’s 8,000-metre peaks without supplemental oxygen.

If there’s a mountain that speaks to you, or you’d love to be part of the full journey, I’d love to hear from you.
