At the age of 31, Doug Wilson underwent a 14-hour operation to remove a life-threatening brain tumour. Just over a year later, he set a Guinness World Record by becoming the first person to run 7 competitive marathons on 7 continents in under 7 days. In this gripping and fast-paced memoir, he shares the story of his struggles with drug and alcohol addiction, mental illness and physical disability - and the extraordinary journey of healing that helped him to turn his life around.
