This is a story about what’s possible.

One woman. 100 marathons. 100 days.

4,200km across Pakistan & India — retracing a colonial line and asking one powerful question:

Can she do it?

Project Salt Run is a live, unfiltered experiment in what becomes possible when one person chooses to act with purpose.

In October 2025, Hannah Cox — a first-time ultrarunner and purpose-led entrepreneur — will run 100 marathons in 100 days, following the Inland Customs Line: a 4,200km colonial boundary built to enforce a devastating salt tax.

She’s not doing this because it’s safe or certain.
She’s doing it because it matters.

This is not a finished story.
It’s the beginning and here’s your invitation to get involved.

The Route

Hannah’s journey follows the Inland Customs Line — a hedge once built to extract profit and enforce suffering.

Starting in Pakistan, she’ll cross into India and run west to east through 9 states, over 100 days, passing her father’s childhood doorstep in Kolkata, before finishing at the India–Bangladesh border.

This isn’t just a route.

It’s a reimagining — from control to conviction, from history to hope.

We live in a world that tells us to wait. To be more ready. More qualified. More certain. Project Salt Run disrupts that — with one radical idea:

You don’t have to be ready. You just have to begin.

This run isn’t about heroism. It’s about showing up.

Not with answers but with action.
Not with guarantees but with purpose.

We’re here to prove what becomes possible when we:

  • Reclaim history with intention

  • Act on what matters

Build belief, one step at a time

Why this matters

Meet Hannah

“I’m not an athlete. I’m terrified of failure. But this is about trying. This is my something.”
— Hannah Cox

Hannah is 41, lives on a houseboat, runs two businesses, and until last year had never run a marathon.

But when she discovered the story of the Inland Customs Line, something clicked.

She didn’t wait to be ready. She chose to begin.

Project Salt Run is her way of turning personal intention into collective movement and inviting others to do the same.

  • Sharing the story with your friends, family and people you work with by sharing our Podcast or engaging with us on Social Media.

  • Our aim is to fundraise £1 Million pounds on Givestar for Climate Action. This money will go to 1% For the Planet and local partners to have real impact in India and beyond.

  • Sponsor a day of the run or donate to help us fund the Expedition via Crowdfunder

 FAQs

  • Hannah’s got a track record of taking on bold challenges and following through. She travelled overland from the UK to Bhutan in 2017, and has travelled extensively. As the Director of The Better Business Network and betternotstop, she has demonstrated leadership and resilience in driving businesses toward positive environmental and social impact

    She completed her first ultramarathon in just five months, has been injury-free throughout her training so far, and has been building up physically and mentally for this for over a year. This isn’t a solo effort. There’s a brilliant team around her focused on logistics, safety, and storytelling to help make this happen.

  • Funds raised on Crowdfunder are going directly towards expedition planning, logistics, and delivery, much of which is spent in advance. As such, they are non-refundable, but we are committed to full transparency and accountability, and any unspent funds would be reserved exclusively for the rescheduled expedition or related impact work.Any money donated to Givestar goes directly to the Charities listed.

  • Many people that fundraise for fundraising expeditions raise on one platform. However we wanted to be clear what money was being raised so we could take on the challenge, and what money the Charities will receive. 

    By fundraising for the expedition on one platform and the charities on another platform we can be fully transparent with everyone who is generous enough to donate to Project Salt Run. 

  • Funds raised on Crowdfunder are going directly towards expedition planning, logistics, and delivery, much of which is spent in advance. As such, they are non-refundable, but we are committed to full transparency and accountability, and any unspent funds would be reserved exclusively for the rescheduled expedition or related impact work.Any money donated to Givestar goes directly to the Charities listed. 

  • Running is more than a physical challenge. She sees it as a powerful way to connect with place, people, and purpose. By running the 4,200km inland customs line, Hannah is retracing a hidden piece of history while opening up conversations about identity, borders, and climate justice. description

  • We’re aiming to run 100 marathons in 100 days — ideally consecutively. But if illness or injury happens, we’ll adapt. We’ve built in medical partnerships, ground support, and flexible planning to allow for a rest or recovery day if needed. The mission is to complete the run safely and meaningfully, not at all costs. We will be honest and transparent about this on our social media, and will be posting daily updates onto Instagram and Tik Tok.

    The Project Salt Run expedition is designed to be a collective effort carried out by a committed team.

    While Hannah Cox is the expedition leader and central to the execution and storytelling of the Project, in the event that Hannah is injured, becomes unwell, or is otherwise unable to complete the run, the expedition will continue with the remaining members of the team unless it is deemed unsafe, unviable, or logistically impossible to proceed.

    Any such decision will be made with full consideration of safety, environmental conditions, and the core purpose of the expedition. The Project will pivot where needed (e.g. changing the route, pacing, or storytelling approach), but will remain committed to delivering the agreed-upon impact and funder deliverables to the best of the team's ability.

  • We have contingency plans in place. These include alternate routes and transport to emergency accommodations and back-up communication systems.

    If we’re stopped short, we’ll document the journey honestly and transparently and seek ways to complete or revisit the route in phases. We are tracing the route of a 1874 map so expect there to be many challenges and changes in the landscape to contend with.

  • We’ve budgeted carefully, built in a funding buffer, and will be fundraising continuously throughout the journey. We’re also building partnerships and applying for grants that can help cover unexpected costs if needed.

    We are also planning to release a plan and strategy for if we are successful in fundraising more than we need for the expedition, with a view that additional financial resources can be funneled into impactful projects.

  • We’ve asked ourselves the same. But the impact of this expedition goes far beyond the flight. We’re using our platform to highlight climate resilience, spotlight nature-based solutions, and amplify Indian voices. We’re also offsetting and reducing wherever we can, and ensuring our footprint leads to long-term, positive change.

    We had researched travelling overland for the team, but the costs and time it would take were prohibitive to what was possible. 

  • It’s about confronting privilege, telling untold stories, and listening to communities on the ground.

    We’re collaborating with local experts, historians, artists, and change-makers to ensure this is a shared platform.

    Hannah’s initial interest in the story was from researching colonial history as her Father is from India.

    We will in fact be running past her Dad’s Childhood home as part of the journey, and visiting places her relatives have been to in the past on the way. 

  • Our plan is to use filtered and purified water systems on the move working with trusted partners. We’re also working with sustainability and health experts to manage hydration safely in high-heat environments.

  • Item descriptionHer training includes heat acclimatisation (sauna work, layered runs), strength conditioning, and nutrition planning with experts. We’ll also be adjusting run times around local climate conditions and building in support stops to keep things safe.

    In the two weeks before she leaves she will spend ten sessions in a heat chamber to help with acclimatisation, which trains the body to better regulate temperature, reduce heart rate and perceived exertion in hot conditions, and improve overall performance and safety during endurance efforts in extreme heat.

  • Funds raised are going towards:

    • Expedition costs: travel, team logistics, safety, documentation

    • Content & storytelling: filming, photography, sharing the journey in real time

    • Community partnerships: supporting Indian-based organisations and grassroots initiatives

    • Creating a blueprint for future climate resilience storytelling and engagement work
