This autumn I walked 100km in six days across the Peaks of the Balkans, through Kosovo, Montenegro and Albania, with nearly 100 current and former McKinsey colleagues. We crossed borders more than ten times and got each other through some very rocky days.

The trek was organised by Treks for Charity, a grassroots initiative run by colleagues for colleagues. Everyone paid their own way, so what you give goes to the charity, not the trip.

I'm raising money for the Mental Health Foundation of New Zealand. New Zealand is where I studied and started my career. Since 1977 the Foundation has been the country's independent voice for better mental health, providing free support for people going through a tough time and running campaigns such as Mental Health Awareness Week.

Any amount helps. Thank you for reading, and for giving if you can.
