Andrew Mok and Simon Whitmarsh are both keen walkers, covering over 2000km a year. They have walked extensively in Britain and Europe and more recently they have enjoyed treks in the US (including many parts of the Appalachian trail), Australia, New Zealand, Andrew's native Hong Kong and Nepal (Everest Base Camp). They are both doctors, a General Practitioner and a Consultant Paediatrician. When not travelling, they enjoy finding new routes near their village in Snowdonia.
