The anticipation for the 2026 TCS London Marathon is reaching fever pitch, with a record-shattering 1.1 million people applying for a coveted spot in the world-renowned race scheduled for April 26, 2026. That’s nearly double the number of hopefuls from just two years ago, underscoring the marathon’s status as the globe’s most popular 26.2-mile event. As the start line draws near, the stories behind the runners—especially those lacing up for charity—are as inspiring as the race itself.
Organizers are expecting around 60,000 runners to set off through the streets of London this year, a testament to the marathon’s ever-growing appeal. The 2025 event set a new benchmark, boasting a world record 56,640 finishers and raising an eye-watering £87.3 million (about $117 million) for a diverse array of charities. Since its inception in 1981, the London Marathon has generated over £1.4 billion for good causes, cementing its place as a cornerstone of the global charity fundraising calendar.
Yet, with such surging popularity comes fierce competition for entry. Only about 5% of the 1.1 million applicants secured a standard place through the official ballot this year. For the vast majority, running for charity has become the primary route into the race. This shift has brought both opportunities and challenges, as fundraising targets climb and the cost of living rises, making the marathon journey both a physical and financial commitment.
Jo Wood from Saltash, Cornwall, embodies the spirit of the charity runner. In 2012, Jo began her marathon journey after the heartbreaking loss of her baby, Jack, at just six days old. Supported by the baby loss charity Sands and mental health charity Mind, Jo found solace in running—and a way to give back. This year, she’s set to complete her eighth marathon, with a picture of Jack on her shirt as she runs to raise funds and awareness for Sands and Mind. "Running a marathon for charity isn't just about raising money, it's about raising awareness—that's why I am running for Sands and for Jack," Jo explains. "I want women to feel they can talk about their babies. I want people to stop shying away from their names, their stories, their existence."
Jo’s dedication has translated into more than £10,000 raised for various charities over eight marathons. Her journey, however, has not been without its hurdles. "Fundraising is hard and has become harder. It's a lot on top of the training, especially when you are raising £2,000 to £3,000," she admits. Creativity has been key—Jo has organized events and reached out to her community to meet her targets, all while balancing the demands of marathon training.
For many, like Kirsty Barker from Ivybridge, Devon, the London Marathon is a bucket-list achievement. After a decade of unsuccessful ballot attempts, Kirsty landed her spot by running for Mind, a charity that has been a lifeline for her. But the fundraising target—£2,500—proved daunting. "At first I thought, oh, that's a breeze, I've got loads of time to do that," Kirsty reflects. "But you definitely underestimate how difficult fundraising is alongside training for a marathon." She’s taken on everything from organizing quizzes to wrapping Christmas presents and doing odd jobs. "It is hard to fundraise when money's tight for everyone—the cost of living is astronomical," she says. "It is really difficult to ask people so it's why I've wanted to do the jobs."
Age is no barrier to marathon dreams. Sue Jackson, aged 70 and hailing from Bradninch, Devon, will be running her first marathon in London for Victa, a charity supporting young people with sight loss. Sue has already met her £2,500 target, motivated by a family history of vision problems. "We have sight loss problems in our family," she shares. "My mother, who's now 101, has macular degeneration but that can start much earlier in life. My grandfather had glaucoma which meant he lost his sight, and I've got cousins who've also got glaucoma or macular degeneration." Sue recognizes, though, that not everyone finds fundraising easy. "I've got a friend who is running for charity and I don't think she is finding it so easy," she adds.
Sarah Jones, a marathon coach and charity adviser known as Good Thinking Jones, has run the London Marathon eight times and helps others make the most of the experience. She’s well aware of the mounting pressures on charity runners. "Most people have full-time jobs and families, they are training for a marathon and raising a couple of grand for charity in a few months. Either of those things could be a full-time job in themselves," Sarah explains. She emphasizes that, while the challenge is real, the value and memories last a lifetime. Sarah also highlights the four main reasons people donate to marathon runners: personal connection, a link to the cause, the challenge itself, and creative fundraising trends—this year, it’s personalized hair bows sold for charity.
Charities, too, are stepping up their support. Marie Curie, the official charity partner for the 2026 TCS London Marathon, has over 700 runners and aims to raise a minimum of £2 million. Each runner is tasked with raising at least £2,500, but they’re not left to fend for themselves. Marie Curie provides a comprehensive support pack, access to training apps and plans, a post-race reception, and even a training day with a GB running coach. Meanwhile, smaller charities like Remap, which designs equipment for disabled people, offer personalized coaching and milestone tracking for their runners, ensuring that every effort counts.
The marathon’s broad appeal is reflected in its participants, from first-timers to celebrities like fitness expert Joe Wicks, who is running to raise money and awareness for the National Deaf Children's Society. The event’s organizers work with over 2,000 charities, and the impact is felt far beyond the finish line—helping causes large and small, and bringing communities together in support of runners’ personal stories.
Looking ahead, the appetite for marathon running shows no signs of slowing. Organizers are exploring the bold idea of splitting the 2027 TCS London Marathon across two days, potentially allowing up to 100,000 runners to take part and raising as much as £130 million for charity. This would see the elite men's and women's races possibly staged on separate days, marking another evolution in the event’s storied history. While no final decision has been made, London’s mayor is keen to work with marathon partners to explore the possibility, highlighting the city’s status as a global sporting capital.
For now, as thousands prepare to take on the 2026 London Marathon, the streets of the capital are set to be filled with determination, hope, and the power of community spirit. Whether running for a loved one, a cause, or the thrill of the challenge, each stride taken on April 26 will carry the weight of countless stories—and the promise of millions raised for those in need.
