If you’ve got a place via the event organisers, we’d love you to join our team and raise money for young people with cancer.
How we'll support you
The difference you'll make
Today in the UK, seven young people aged 13-24 will hear the words: “you have cancer.”
It’s most likely the toughest and scariest thing they’ve ever faced – and it takes an unstoppable team to get them through it.
By taking on a challenge for Teenage Cancer Trust, you become part of the team – because the money you raise helps fund our specialist hospital units, nurses and youth workers.
Your support means young people don’t face cancer alone. You’re helping make sure they have the best expert care from a friendly, dedicated team, alongside others their age they can relate to.
We’re the only UK charity providing specialised nursing care and support for young people with cancer – and we receive no government funding, so we couldn’t do it without you.
