A woman from Greater Manchester, UK, has run 100 marathons in several South Asian countries in 100 days in memory of her late father.
This woman’s name is Hannah Cox, she is 41 years old. After her father’s death, she decided to visit her father’s birthplace, India. For this, she chose the 4,200 kilometer long ‘Inland Customs Line’.
However, Hana initially planned to cover the route by car, not by running. But after starting the race in May 2025, she decided to run the entire route. For this, she had to run 100 marathons in a row over 100 days.
Hana reached her final destination through Bangladesh along the historic ‘Inland Customs Line’, a line once used by the British East India Company to transport goods.
“Running through India is always stressful,” says Hana. “It puts extra pressure on the senses. You have to be aware every moment of every day.”
The woman from the UK added, “The scenery is different, the traffic is different. I tried to follow a certain route, but my body felt different every day.”
Hana said she finished the race despite suffering from scoliosis and an autoimmune disease. She ran for a week while suffering from acute gastroenteritis.
He also said that Hana had to go through terrible pain for the last three days.
“My left leg is pretty badly injured, I’m going to the hospital. But yeah, I’m fine, I’m glad I don’t have to run today,” Hana said.
Hannah’s inspiration for this journey was her late father, Derrick Cox. Derrick was born in Kolkata, India. He moved to the UK in 1953. He died in 2011.
Hannah’s ancestors were Anglo-Indian, some of whom worked for the British East India Company.
“I wanted to create some connection with that country, so that I could follow my family’s history back to 1799,” Hanna said. “I heard about something called the Inland Customs Line. It was a big customs line that ran through India during the British Empire.”
Hana started searching the internet for the ‘Inland Customs Line’. But she couldn’t find much information. She started researching the route in 2014. Now, 12 years later, she believes she is the first person to have walked the entire route.
So far, Hannah’s ‘Project Salt Run’ has raised more than £75,000 for various environmental organizations.
