Many of you will know that Arlo was honoured to win the Allergy UK Child Allergy Hero Award in 2018. Arlo was presented his award by the inspirational Dr William Frankland, 100 years Arlo's senior. Dr Frankland sadly died this month, and Arlo wants to complete his marathon walk in memory of Dr Frankland and the wonderful things he did to make the lives of allergy sufferers safer.

Arlo only has 12 days to complete his challenge, and will be walking every day in a different fancy dress outfit!
