Dest and Rosoa travelled 150 miles through rough terrain and rivers to reach our mission in Madagascar, so that their daughters Vaviroa and Nambina could receive the life-changing surgery they so desperately needed to live happy and healthy lives.

How far could we go to help a child smile?

Walk, run or cycle 15, 50 or 150 miles this October - whichever distance you choose, your challenge will recognise the incredible journeys many families endure to access treatment and end their child's pain and isolation.

Let's make our miles count! Go team AS Watson!
