Because a cure can't wait 🩵

Every day, 36 people in the UK hear the words, "You have a brain tumour." For many families, life changes in an instant.

By taking on the Tokyo Marathon 2027, you can help The Brain Tumour Charity move further, faster towards a world where people with brain tumours live longer and better lives. As the world's largest dedicated funder of brain tumour research, the charity is driving pioneering research, providing life-changing support and campaigning for better care, because a cure really can't wait.

Take on one of the world's most iconic marathons and experience the unforgettable atmosphere of the Tokyo Marathon 2027. From the electric start to the incredible crowds lining the streets, every mile is an opportunity to achieve something extraordinary while making a life-changing difference.

Thanks to supporters like you, in 2025/26 we provided life-changing support to more than 12,500 people and invested £6 million into pioneering research for kinder, more effective treatments. But there's still so much more to do. Brain tumours remain the biggest cancer killer of children, teenagers and adults under 40 in the UK.

"Running a marathon is a roller coaster, full of joy and fear in equal measures. But The Brain Tumour Charity made it an easier ride as they guided me through it all, from the moment I said 'yes' to standing on the start line."

When you join Team Brain Tumour Charity, you'll receive dedicated fundraising support every step of the way, all while helping fund vital research and ensuring no one faces a brain tumour diagnosis alone.
