A global movement for local impact.

Challenge for Change is a worldwide movement fueled by a shared commitment to children’s futures.

In 2025 we achieved over 46,000 kilometers, the distance around the globe, to raise funds for local charities that provide life-changing support to children in need. In 2026 the target is to collectively achieve 133,000 kilometres by covering Part 1 of the perimeters of the 7 continents of the world.

This is more than a physical challenge. It’s a powerful network of friends, colleagues, and communities uniting to create change that transcends borders. Millions of children face barriers to education, healthcare, and safety every day. But global challenges require collective solutions.

Every step, every kilometre, every effort contributes to a brighter future, transforming the lives of children through emotional, educational, and financial support.

Be part of something extraordinary.
