Chamonix-based Dutch mountain guide, Roeland Van Oss, set out to climb all 4000m peaks in the Alps in a summer, without using any powered transport to travel between them.

In a year where the effects of climate change were felt across Europe more than ever, Roeland wanted to set an example of how we can all do small things to impact change.

Just a few weeks into Roeland’s challenge tragic news broke of a colossal Glacier collapse on the Marmolada, in the Dolomites.

By foot and by bike, Roeland ticked off all 82 peaks in just over 10 weeks.
