My name is Thalia, I am 13 yrs old. Three years ago I was diagnosed with an aggressive brain tumour. The past three years have been very hard. I had three surgeries, chemotherapy and radiotherapy.

The tumour made it difficult for me to walk and do many of my activities but I fought to regain them. I love being outside and walking with my family. I feel blessed that my tumour is currently stable. However, many kids die from this disease because there are no treatments.

That is why we are walking the Nine Edges Challenge so we can raise awareness and money for OSCARs.

OSCAR's Paediatric Brain Tumour Charity are walking the Nine Edges Challenge in The Peak District to raise money to support children with brain tumours and their families, raise awareness of signs and symptoms of this terrible disease, and fund research into better and kinder treatments.

We will be walking twelve years to the day that Oscar Hughes died of a brain tumour aged just 9. The charity that bears his name has helped so many other children in the same situation and the team taking on the walk are doing so to help even more.

To learn about OSCAR's - past, present and future- head to oscarscharity.org or follow @oscarscharity on social media.

And if you choose to donate, don't forget to add GiftAid!
