Running 100 marathons to Raise £1mn for the Planet

Building a Legacy of Business Led Environmental Action

Project Salt Run is teaming up with 1% for the Planet to raise £1 million and create a legacy that redefines what business leadership for the planet can look like.

Join us in building a lasting legacy for business, for people, and for the future.

What is Project Salt Run?

Project Salt Run is a bold endurance challenge built around a simple but powerful truth: action speaks louder than intention.

In October 2025, sustainability advocate Hannah Cox will run 4,200 km across India — one marathon every day for 100 days — following a forgotten colonial boundary known as the Inland Customs Line.
Through this journey, she aims to raise £1 million to power climate action and environmental giving.

Funds raised will be shared between:

40% → 1% for the Planet
20% → Frank Water
20% → ClientEarth
20% → Big Change
