David Williams, seventy-four years old and a long-time resident of Flinders Island, Tasmania, tells the story of his lifelong running adventure. An Unstoppable Runner describes the physical and mental challenges he has encountered in such diverse locations as the blister-making Simpson Desert, muddy New Zealand forests, fun runs, and many international marathons and ultra marathons. It also reflects on the life and running lessons he has learned along the way. His stories will not only inspire men and women of all ages to get off their couches and bring adventure back into their lives, but are also designed to promote health and well-being to the wider community. One of the motivating forces behind writing An Unstoppable Runner was to use it to raise funds for Cancer Council Tasmania, so all profits and royalties from the book will go towards helping cancer sufferers. David has had bowel cancer and he and his wife lost their daughter Allison to this dreadful disease at the too young an age of twenty-eight. The foreword to An Unstoppable Runner has been written by the world-famous runner, Australia's very own Pat Farmer AM. Pat's enthusiasm for us all getting fit and healthy is well known. Apart from running as often and as far as possible, David has lived with his wife Dale on remote Flinders Island in Bass Strait for the past twenty years. When he is not running, David is deputy mayor of the local council and has served the community as a councillor for over fifteen years.
