In 2008 and 2009, Simpson took part in a BBC programme called "Top Dogs: Adventures in War, Sea and Ice". It saw Simpson unite with fellow Britons Sir Ranulph Fiennes, the adventurer, and Sir Robin Knox-Johnston, the round-the-world yachtsman. The team went on three trips, each experiencing each other's adventure field. The first episode, aired on 27 March 2009, saw Simpson, Fiennes and Knox-Johnston go on a news-gathering trip to Afghanistan. The team reported from the Khyber Pass and the Tora Bora mountain complex. The three also undertook a voyage around Cape Horn and an expedition hauling sledges across the deep-frozen Frobisher Bay in the far north of Canada.
