The Great North Run is a huge challenge but one of this year's participants is no stranger to those.
Ewan Bowlby from Hexham in Northumberland was diagnosed with a brain tumour in his early 20s and has spent the last few months training for the half-marathon. Despite the knowledge that his life may be cut short, Ewan has packed a number of life events into the last few years and he says that having things to look forward to and to work for that have really kept him going.
Between Ewan's multiple cancer treatments and four major operations, he has been in the process of completing a PHD, becoming a published academic and a Maggie's Centre Ambassador. He got married to wife Karlee, an artist and illustrator, in May and described it as "the best day of his life."
