Running 100 marathons in 100 days, having never run 18 months before
Title: From Zero to 100 Marathons: The Unlikely Journey of a First-Time Runner
The worn soles of Hannah Cox’s running shoes bear witness to an extraordinary feat, patched with fragments of car tires and coated in the orange dust of the Indian landscape. These trainers have traversed far more than a single 26.2-mile distance. While most marathon runners experience debilitating pain the following day and swear off the sport forever, Cox faced the prospect of running another 26.2 miles, and then another, and another, for 100 consecutive days across India. The magnitude of this undertaking is particularly striking given that just 18 months prior, she had never run a step. This epic, emotional odyssey is literally stamped into the fabric of her footwear.
For years, Cox, now 41, had envisioned an ambitious route but remained undecided on the mode of travel. Following the death of her father in 2011, she developed a deep interest in her Indian heritage, specifically focusing on a 4,200km path historically used by the British during the 19th century to enforce a controversial salt tax. This route, which included the Great Hedge of India—a customs barrier established during British rule—became the focal point of her planning. In the summer of 2024, a chance reunion with a friend reignited her passion. When the friend asked if she was "still obsessed with that hedge," Cox resolved to undertake the journey. However, the friend’s suggestion that she should run the entire distance took her by surprise. This comment planted a seed of determination, leading Cox to join a local running club in Manchester.
Her training regimen began modestly, with 30-minute runs three times a week. As her stamina improved, she transitioned from 5Ks to 10Ks, eventually incorporating consecutive running days to prepare for the physical demands of the Indian expedition. To test her endurance, she tackled rigorous challenges such as "20 20 20"—running 20km every weekday for 20 days—and completed seven marathons in seven days spanning the UK from coast to coast. These achievements bolstered her confidence that "Project Salt Run" was viable. She subsequently assembled a support crew, secured a van, and set a fundraising goal of £1 million for environmental charities.
Despite her physical and logistical preparation, Cox was unprepared for the chaos of Indian roads and the severe illness that would plague her. "Everyone tried to put me off at first - people just didn't believe I would actually do it," Cox recalls. Nevertheless, on October 26 of last year, she launched from the Attari-Wagah border between Pakistan and India, heading toward Kolkata, located just miles from where her father, Deric, was born.
Adhering strictly to the historical route, Cox endured varying terrains. Some days involved running 42km along monotonous highways, which she described as "boring as hell," while others took her through nature reserves, alongside canals, and across agricultural fields. The roads were fraught with hazards, including cows, snakes, and goats, as well as drivers frequently using the wrong side of the highway. The dangers were real; Cox sustained a scar on her right leg from a collision with a motorbike. In certain regions notorious for fatal tiger attacks, she even required a police escort. The environmental conditions were harsh, characterized by intense heat, dust, and smog. Although she spent two weeks in a heat chamber to acclimatize beforehand, the reality proved unlike anything she had previously experienced.
Compounding the physical strain was a bout of sickness that contributed to her losing over 10kg during the challenge. One severe episode coincided with a surreal encounter at the Taj Mahal on day 24. "We met Richard Branson at the Taj Mahal," she explains. Branson was in India to host a charity cycling event. The previous evening, he had invited Cox to dinner at a high-end hotel. "I had one sniff of an Old Fashioned cocktail and I was like: 'oh my god, I'm going to be sick'. I had to run to these really fancy toilets and I was sick everywhere."
The following day, she faced the daunting task of completing a marathon while battling illness. Five participants from Branson’s charity event joined her, but Cox remained sick by the roadside throughout the day. "I just knew I had to finish," she says. To manage the grueling schedule, Cox would rise early each day to complete some miles before the
