Jo Vasey, 36, of Beville, will take on the 26.2-mile course on April 13 to help send five-year-old Zane to Chicago for another specialist brain scan to help him cope with a rare condition. Jo pictured with Zane said: I know Zane as his dad plays football with my boyfriend. Zane inspired me to run this marathon, and is what makes me get out of bed on a cold, horrible, miserable rainy morning to put in the legwork for my training. Zane, of Essex Road, Huntingdon, suffers from CCMS, a genetic mutation of blood vessels in the brain which form lesions, called cavernomas that can haemorrhage at any time and cause a seizure, stroke or death. To help him live with his condition, Zane must visit Dr Issam Awad at the University of Chicago once a year for a unique MRI scan which shows how his brain is affected.
