UK Woman Runs 100 Marathons in 100 Days Tracing India's 'Great Hedge'
Imagine a giant, prickly wall that the British built long ago in India to collect a tax on salt.
It was so long and hidden that most people have forgotten about it.
A woman from the UK named Hannah Cox is now running 100 marathons in 100 days across India to follow where this old wall used to be.
She's doing this partly because her family was part of the British system back then, and she wants to learn about that history.
She also wants to remind everyone about this forgotten wall, not as a barrier, but as a path to connect with history and the land.
While running, she is also trying to raise a lot of money for charities that help the planet and people.
UK entrepreneur Hannah Cox is running 100 marathons in 100 days across India, starting October 26.
Her 'Project Salt Run' traces the route of the historical 'Great Hedge of India', a British-era boundary built to enforce a salt tax.
The 4,200 km journey spans nine Indian states, from the Pakistan border to Bangladesh.
Cox, whose ancestors worked for the British East India Company, aims to acknowledge colonial history and transform the symbol of division into one of connection.
The project also seeks to raise £1 million for four charities: 1% for the Planet, Frank Water, Big Change, and ClientEarth.
