I'd like to introduce you to my little 3 year old HERO........Sienna.

My name is Allan Murray, and as a 74 year old cyclist I'm promising to ride 300 kilometres in the month of October as I take part in the Great Cycle Challenge which raises funds to fight against that mongrel disease, CHILDHOOD CANCER.

In those hours in the saddle I'll have Sienna's heart rending story that began on 20th March of this year after being diagnosed with Melanoma at the front and centre of my thoughts.

Her bravery and resilience as she underwent multiple invasive surgeries and now to undergo a year of fortnightly infusions deserves to be recognised.

(Her story is on the Great Cycle Challenge website)

That's why I'm am riding and raising funds to support the Children's Medical Research Institute to continue their work into the prevention, diagnosis, treatment and finding a cure for childhood cancer.

Please support my challenge by making a donation through my fundraising page to give these kids the brighter futures they deserve.

Together, we can save children's lives.

Thank you for your support.
