For eight-year-old Emi Valo, riding a bicycle is about more than fresh air and fun.

It is a chance to give something back.Just a few years ago, Emi was spending her days in hospital undergoing treatment for leukaemia.

Today, cancer-free and full of energy, she is helping to raise thousands of dollars for paediatric cancer research, the very field that helped save her life.Alongside her family, classmates and local supporters in Ohio, Emi has already raised more than $5,000 through a fundraising campaign linked to Pelotonia Kids, an initiative that supports childhood cancer research.

What began as one family's way of showing gratitude has grown into a wider effort to help children who are still facing the challenges she once knew all too well.It is a reminder of something often overlooked.

Behind every improvement in childhood cancer survival rates lies years of research, clinical trials and scientific work that most patients never see.
