Lizzy Hawker is one of the greatest ultra-distance runners this country has ever produced. She is the first woman to finish on the overall podium of the Spartathlon, one of the world's toughest footraces, and has won the legendary The North Face Ultra Trail du Mont Blanc five times in its ten year history, the only person, man or woman, to achieve this. 'Runner' is the story of her journey and will get inside the head of the physical, mental, and emotional challenges that runners go through at the edge of human endurance.
