It is September 2009, and Adrian finds himself alone in Switzerland on a work assignment.He decides to use his time there to the fullest by embarking on a rigorous running regime; something he has not done for over a quarter of a century.Adrian's determination to get fitter, faster and stronger shows no sign of abating. On 22 May 2010, his run that day starts as uneventful as most of the others have done. But this particular day is different - this is no ordinary run. It will, without doubt, go down in Adrian's life as the Run to End All Runs.
