Sian Pritchard-Jones and Bob Gibbons met in 1983, on a trek from Kashmir to Ladakh. By then Bob had already driven an ancient Land Rover from England to Kathmandu (in 1974), and overland trucks across Asia, Africa and South America. He had also lived in Kathmandu for two years, employed as a trekking company manager. Before they met, Sian worked in computer programming and systems analysis, but was drawn to the Himalaya en route from working in New Zealand. Since they met they have been leading and organising treks in the Alps, Nepal and the Sahara, as well as driving a bus overland to Nepal.
