Sam Lyon, accompanied by friends Matthew, Tom, Elliott and Rob took on the 12km Nuclear Races Fallout course in Essex on Saturday 7 November.

The challenge began when Matthew suggested the group run for charity after hearing that Sam’s mum Janet had died. Sam chose Friends of Roxburghe House Grampian, as Janet spent her final week at the specialist palliative care unit in Aberdeen.

Sam grew up in Aberdeen and now lives in London and had never run a muddy obstacle course, but says his mum was a brilliant athlete and a member of Aberdeen Amateur Athletic Club - and that she “would have been cursing” him if he had taken it at a casual pace.
