In 2015, extreme endurance adventurer Sean Conway became the first and only man in history to cycle, swim and run the length of Britain. This year, Sean raised the bar once more by taking on the greatest challenge of his life - a self-supported, 4000+ mile, continuous Ultra Triathlon circumnavigating the entire coast of mainland Britain. The results of his herculean effort are seen in the exclusive three-part series Sean Conway: On the Edge.
