Challenge Yourself in the Chilterns – And Walk for Young People Facing Cancer
Take on the Chiltern 50 Ultra Challenge – a stunning looped route through some of the finest countryside in the Chiltern Hills. With rolling trails, nature reserves, historic paths, and sweeping views, it’s an unforgettable day out – and every step helps Teenage Cancer Trust support young people with cancer.
Starting and finishing at basecamp in Henley-on-Thames, you’ll join up to 2,000 adventurers walking, jogging, or running at their own pace – with options for the full 50km, a 25km, or a 10km route. Go solo or take on the challenge with friends or colleagues.
You’ll be fully supported from start to finish – with rest stops, snacks, meals, drinks, medical teams, and optional camping & transfers. Cross the finish line to a celebration with a special medal, T-shirt, and a huge sense of achievement.
Just a short trip from London, this is the perfect end-of-summer challenge in a truly scenic setting.
Go further in 2026 – sign up for the Chiltern 50 Ultra Challenge and help change young lives with every kilometre.

Why support Teenage Cancer Trust
We create world class cancer services for young people in the UK, providing life-changing care and support so young people don’t have to face cancer alone.
