David Clark is a formerly obese alcoholic and fast food junkie who found a new life in running. Now, 13 years after his transformation, he shares his inspiring story of taking running to the extreme edge of his physical and spiritual breaking points. Having run more than a hundred races, including the Leadville 100-Mile Trail Run and the Hardrock 100, David has achieved unimaginable success in the ultramarathon world, considering his humble start.

Part narrative, part practical, this adventure takes you to the foothills of Ethiopia and the ‘town of runners’; to the training grounds of world-record-holding marathon runners in Kenya; racing across the Arctic Circle and the mountains of Europe, through the sweltering sands of the Sahara and the hostility of a winter traverse of the Pennine Way, to witness the incredible natural movement of runners in these environments.

Growing up in the Canadian Rockies, the mountains have always been home for Jenny Tough. Travelling the world, she's always discovered commonalities with mountains—and mountain people. Her major project is to run solo and unsupported across a mountain range on every continent where indigenous mountain people live isolated from the outside, urban world. Running solo and unsupported comes with obvious logistical as well as physical challenges, but running is also a common language.

In It for the Long Run is ultrarunner Damian Hall’s story of running a first marathon aged 36, dressed as a toilet, and representing Great Britain four years later. His midlife-crisis running problem escalated to 100-mile ultramarathons and record-breaking bimbles, culminating in his 261-mile Pennine Way run in July 2020.

In 2017, world-class ultrarunner Hillary Allen was at the top of her sport - and it felt like she was running on top of the world as she competed in Norway's Tromsø Skyrace. Allen was nearly halfway through the 50-kilometer race when she fell 150 feet off an exposed ridge, fracturing her back and breaking multiple ribs, both feet, and both of her lower arms. Beginning with the dramatic story of her accident and rescue, Out and Back: A Runner's Story of Survival Against All Odds recounts Allen's fight to return to the life she loves.
