Running 100 marathons in 100 days, having never run 18 months before
Title: From Zero to 100 Marathons: The Unlikely Journey of Hannah Cox
The battered soles of Hannah Cox’s running shoes narrate a tale far more grueling than a single marathon. Scuffed by dust and reinforced with patches of car tire, these trainers have logged distances that defy conventional limits. While the average marathon runner might collapse in exhaustion the day after their first 26.2-mile race, swearing off the sport forever, Cox faced a far more daunting prospect: running that distance for 100 consecutive days across India. The most shocking aspect of this feat? Just 18 months prior, she had never run a step.
This extraordinary and emotionally charged endeavor is etched into her footwear. For years, Cox, now 41, had envisioned a specific path but remained undecided on the mode of travel. The inspiration struck following the death of her father in 2011, which deepened her connection to her Indian heritage. She became fixated on a 4,200km route established by the British in the 19th century to enforce a contentious salt tax, a border marked by the infamous "Great Hedge of India."
The catalyst for action arrived in the summer of 2024 when a friend asked if she was "still obsessed with that hedge." Realizing it was time to act, she did not anticipate his suggestion: "I think you should run it." That comment planted a seed. Cox joined a running club in Manchester, starting with just 30-minute sessions three times a week. As her stamina grew, her distances expanded from 5Ks to 10Ks, and she began training for back-to-back running days, essential for her survival in India.
To test her resolve, Cox tackled rigorous challenges, including the "20 20 20" drill (running 20km daily for 20 days) and completing seven marathons in seven days across the UK. These tests convinced her that 'Project Salt Run' was viable. She assembled a support crew, secured a van, and set a fundraising goal of ÂŁ1 million for environmental charities.
Despite her physical and logistical preparation, Cox was unready for the chaotic reality 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.
On October 26 of last year, she departed from the Attari-Wagah border between Pakistan and India, heading toward Kolkata, located just miles from where her father, Deric, was born. Sticking to the historical route, her days varied wildly. Some stretches involved running 42km along monotonous highways, which she described as "boring as hell," while others took her through nature reserves, canals, and agricultural fields.
The environment was hostile and unpredictable. The roads were shared with cows, snakes, and goats, and drivers frequently switched to the wrong side of the highway. Cox sustained a scar on her right leg after a collision with a motorbike. In areas notorious for fatal tiger attacks, she even required police escorts. The weather was oppressive—hot, dusty, and smoggy. Although she spent two weeks in a heat chamber to acclimatize, nothing could have prepared her for the actual conditions.
The physical toll was severe, exacerbated by sickness that caused her to lose over 10kg. One particularly difficult episode occurred on day 24, coinciding with a surreal meeting with Richard Branson at the Taj Mahal. Branson was in India hosting a charity cycling event.
"We were walking around the Taj, and I was feeling progressively worse," Cox explains. The night before, Branson had invited her to dinner at a luxury hotel. "I took one sniff of an Old Fashioned cocktail and thought, 'Oh my god, I’m going to be sick.' I had to rush to the fancy toilets and vomited everywhere."
Despite her condition, the next day required her to run a marathon. Five participants from Branson’s event joined her. "I was sick all day, sitting by the side of the road, but I knew I had to finish," she says. To manage the distance, Cox would rise early to complete some miles before the sun fully rose, pushing through the pain and exhaustion to complete her epic quest.
