Mom and daughter, Kate and Hannah, will be running together in memory of their son and brother, Sam Polley. Travelling from South Africa to run, this year will be Kate's second London Half Marathon and Hannah's first. 

The duo will also be raising money for The Skye High Foundation and their Purple Butterfly campaign, which raises awareness of the loss of a baby in a multiple birth. Kate's book "My Purple Butterfly" was written exclusively for The Skye High Foundation.
