Jamie and Dave are taking on the Great North Run in September and Manchester Half Marathon in October for Derian House Children's Hospice in Chorley. They provide care and respite for children with life limiting or life shortening conditions. To provide their services to the children and families of the NW of England it costs them over £5m per year - with less than 12% of this provided by any statutory funding.  Each half marathon is a 13.1 mile journey through the city centres and surrounding areas.
