Marianne Fatton is a world-class ski mountaineer and trail runner who brings both strength and elegance to the mountains she calls home.

Representing Switzerland, Marianne has established herself among the elite in ski mountaineering, with multiple podium finishes at the ISMF World Cup and World Championships. Her versatility allows her to excel across disciplines—from explosive vertical races to demanding individual formats—always combining endurance, technique, and determination. In recent years, she has also made a strong transition into trail running, proving her ability to compete at the highest level year-round.

Marianne’s approach to sport reflects a deep connection to the mountains and a commitment to continuous progress. Her training often begins before sunrise or stretches into the evening hours, where changing light and unpredictable conditions demand full focus and reliable gear.

As a Suprabeam ambassador, Marianne depends on powerful and precise lighting to support her performance in all conditions. Whether navigating technical terrain in the dark or preparing for competition, having the right equipment allows her to train with confidence and stay fully immersed in her environment.
