At the end of 2012 McCarron crossed 1000 miles of the Empty Quarter desert with Alastair Humphreys, roughly following the route of explorer Wilfred Thesiger and pulling a cart loaded with supplies.
Other journeys include: 14,000 miles by bicycle from New York to Hong Kong; a folding bike trip around the British Isles to climb the Six Peaks; a human-powered descent of the longest river in Iran, the Karun; and a crossing of Argentine Patagonia on horseback.
[1] In 2017 he was the recipient of the Royal Geographical Society's Neville Shulman Challenge Award, and spent a month with the Israelite Samaritans documenting the way of life of perhaps the world's smallest and oldest ethno-religious group.
Most recently McCarron has walked on and written about trails in the Balkans and the Caucasus, and has been working in Iraqi Kurdistan and on the Indian Ocean island of Socotra.
Most recently, McCarron presented a documentary about the Samaritans, with whom he spent time in their village of Kiryat Luza on the West Bank in the Holy Land.
