Twenty One Twelve: A Human Powered Adventure Across Australia. In 2019, in pursuit of a life-long dream, American ultrarunner, Katie Visco, sets off on foot across Australia with her husband, Henley Phillips, as support on a bicycle. Starting out on the coast in Darwin, Northern Territory, the couple runs and bicycles 2,112 miles through some of the most formidable and harsh environments on the planet to reach the coast in Adelaide, South Australia. What begins as a way for Visco to push her own limits ultimately becomes a story of togetherness as the two support each other through thick and thin, sand and wind, flies and heat under the unrelenting Outback sun. The journey is one that highlights the absolute best of the human spirit.
